where to buy 16GB micro sdhc class 6 from?

amazon is too annoying, brings up anything and everything, don't trust ebay
mymemory has class 2 or class 10 for £80+
help

NM, found a thread on this forum and got one ordered. yay!

from? link?

Bought all my SD Cards from these guys http://www.mobymemory.com/micro-SD.asp

this thread isnt in the wrong section at all.............

Can I ask why people care about the class? I've just got a class 2 32gb card from Vodafone for £89. I've not noticed any problems or slowdown taking pictures or playing media...which are the only things my card is used for. Transfers are no slower than any other device I connect via USB.
What's the big fuss?

it's for running apps from in the (hopefully) near future.
class 6 means (i think) a minimum 6Mb/sec transfer rate
oh, got it from memory cow

Yes, but most people have suggested they see no difference when using apps2sd with the "slower" cards. It seems there's a lot of assumptions being made leading to actual sales decisions where it may not be needed.
See this fellow who thought a faster card would solve his issues: http://forum.xda-developers.com/showthread.php?t=708859

So where is no differences between class 2 and class 6 ?
Because i have dilemma now, i want to buy some high capacity microSD card, and if i take 32GB it will be class 2, and if i take at same cost 16GB card it will be class 6.
And does any body try to buy 32GB card from Ebay ? ( i am worrying that 32GB is not GB, its Gb, and that means just 4GB )
Thanks for help

i woul;dn't trust the cards off ebay tbh

I went ahead and bought the Transcend 16gb class 6 card through OFFTEK. It arrived with the adaptor, and was very prompt.
http://www.offtek.co.uk/item_detail....at=1&subcat=74
Pretty good price too. I just copied everything to my desktop, swapped cards and copied back.
The new card works great, but i did notice that the full card size is stated as "14.96gb" on the phone, rather than 16.

I also wonder if there is a difrence between a class 2 or class 6 card when playing movies, apps or taking pictures on your SD card.
because that would make the difrence between going for a 32gb or 16gb card.

well, i noticed a difference when copying files. both cards broke 10MB/sec on large files, but the old card dropped damn quick when copying loads of small files - e.g photos.
i'd imagine it would be like this when looking through an album or flicking from one image to the next. it's not about the max speed, but the minimum.

hi mate,
what do you think about this one

37 euro's for class 10/16GB seems waaay to cheap for me.
I also doubt it's a micro sd

THE CLASS OF AN SD CARD IS TO DO WITH ITS WRITE SPEED NOT ITS READ SPEED, YOU WONT NOTICE ANY DIFFENCE WHEN READING FROM IT

Perfectly normal not to get the quoted capacity, combination of space lost due to formatting and the tendency of hardware producers to size storage media in decimal (ie. 16 000 000 000 bytes) rather than the binary equivalent - which the OS displays (16 x 1024 x 1024 x 1024 bytes).
I've confused myself with that statement - in short the hardware manufaturers use a commonly accepted, flattering but actually incorrect notation to lead you to believe that you are getting more for your money - HTH

Kingston make a 16gb class10, but it's pretty expensive (~100€)

Oh, and by the way, up to what class num can the Desire actually handle ?

I picked up my SanDisk 16GB Class 6 from the Carphonewarehouse when i went and got my Desire,,, i beleive it was £42
IMO i have always used Class 6 cards, i think they are the business, i dont care for read and write speeds i just need something that works and is reliable, SanDisk have always had my back so there ya go

MicroSd Card Size Limit

Sorry if this has been answerd alread..I have search google and here with no luck...Just purchased the Gtab (currently charging) and I want to get an sd card 8 16 or 32 .. Would like to get a class 6 16gb but don't want to pay 70 to find out it will not support the full 16..

Gtab will support up to 32gb microsd. so yes 16gb will work just fine, this is what I am currently using as I don't want to pay around $100 for a 32gb card. I am using a 16gb class 4 (Patriot memory) and it works really well, I have also tested a 16gb class 2 (SanDisk) and I really don't see any difference in the feel or performance. I assume that higher class would be faster data transfer but haven't had any issues with a class 2 or 4 yet (I keep my music library on SD2).

I purchased a couple of those from NewEgg. That manufacturer has given me NOTHING but problems with their SDHC cards.
Just an FYI

What were the problems you were having with the a-data?
Sent from my T-Mobile myTouch 3G Slide using XDA App

I have an OEM 32GB Sandisk microSD, and it works just fine in the device (so far).
As for ADATA, I have a relationship with them now which I will pass on... in 2008, my wife had gotten me a Class 6 16GB SDHC by ADATA, it had a "lifetime limited" warranty. Last July, I started using it pretty heavily in my Pandgital Novel, a LOT of remove / reinserts as I was testing mods on it. It quickly disintegrated (literally, the outer case fell apart - I have never seen anything like it).
So, I called them. Several times. At first they weren't going to honor the warranty as they claimed it was unusual wear and tear. But, I was persistent and slightly irate at points ("I will never buy from you again, and neither will anyone in Slatedroid!") and they eventually caved and gave me an RMA. It was a long process but my replacement card is now on its way to my home. So, in the end, they did honor the warranty but "the squeaky wheel gets the oil", as the saying goes.

Very insightful..Thanks for the replies..Won't know till I am there.Might just get a 32gb and be done with it...At work and can't wait to get off so I can root this thing...

Just a reminder (its been pointed out in this forum and many others), but you're wasting your money on a "faster" class micro sdhc card for use in a g-tablet. The higher class cards are all with respect to WRITE speeds. You also need special hardware to take advantage of the faster write speeds. Usually fast writing hardware is only found in expensive digital SLR cameras. If your device doesn't mention the ability to make use of the faster write speeds then a class 2 card will perform identically to a class 6 card, etc.

I am 95% sure that Adata makes the cards that Micro Center sells cheap, under their name.
With that in mind, I have bought many MicroSD(HC), SD(HC), and USB flash drives over the years from them, and had a few fail. However, they have a lifetime warranty on them too, and all I have to do is take it to the store, and they replace it on the spot. No receipt, nothing.
They don't have a 32GB MicroSDHC card yet, but I am eagerly waiting for them to so I can get one. Best they got for now is a 16GB for $24.

Like roebeet mentioned... nothing but failure after failure on all of them. Lifetime warranty or not, it's not worth the hassle returning it, copying data, etc..etc..
I guess, it all depends on if your time is worth more to you then a few dollars more for a "name brand" SDHC card that won't fail after a few months.

Size of card.
I answered this 3 weeks ago. The limit is 32GB, and my Sandisk works well on my stock gTablet. I bought the micro card locally at a Verizon Wireless store. No other retailer in the Philadelphia area carried a 32GB micro card, not even on their Web sites. I have audio and video files on the card; no hiccups when playing same.

64GB microsd limt
According to the manual (gttp://w w w .viewsonic.com/assets/104/20736.pdf sorry can't post URLs yet) on p. 54:
"The G Tablet currently supports up to 64GB micro SD cards. It
is recommended that the G Tablet be used with at least a 32GB
micro SD card to ensure the best user experience."
I've been using a 32GB SanDisk class 2 which seems to be working well.

64GB microsd...

So has anyone taken the plunge and actually tested out a 64?

Try to find one. I did and failed completely. 64GB SD and CF, yes. But no micro I could find anywhere. I got a couple of 16s from Amazon, and almost filled them with media (left room for a backup folder on each) and I am going to rotate them.
Here's a 32GB Class 6 for only $56 http://www.mwave.com/mwave/SKUSearch_v3.asp?px=PW&scriteria=AB02429

It would be nice to know if the gtab supports SDXC as well as SDHC. What say you Viewsonic?

Supposedly there is no real distinction between SDHC and SDXC 3.0 specs. Hardware wise it is the same. Other OSes (Android?) should be able to support SDXC with support drivers. This would mean any current SDHC device can be SDXC with a software update. SDHC won't support SDXC 4.0 specs (which isn't final yet) which features higher data transfer rates. That is according to wikipedia at least...http://en.wikipedia.org/wiki/Secure_Digital
I don't believe micro SDXC cards exists just yet.
I still don't understand why manufacturers aren't using full size SD cards, they're cheaper and with tablets the size they are, a full size SD won't add much to it. It would save everyone a lot of money.

^ This. On an iphone sized device, sure uSD makes a decent savings size. On a 7+ inch tablet not so much. I wouldn't mind playing around with some USB SD readers and seeing if they work. If so you might be able to fit one somewhere in the chassis. There is the USB port, just need space to solder to the leads and add a hub and/or reader.

I think I have the same Patriot 16GB SDHC Class 4, and just like the reviews on NewEgg state it seems to run @ Class 6 speed. The price was good and so far I'm happy with it.

Shortly after I posted that, I went and looked around and couldn't find one either.
I also realized I am only running a 16GB SD card... thought I had a 32. Doh!

[Q] Micro SD suggestions?

Not sure if this is the right forum, but looked like accessories was the best bet.
Im looking at 32G cards, but open to 16 as well. Just switched to Android, so would be good to know others experiences, and whether there is something I cannot do with a Class 4, for example or whether you see any lags with other cards you have used etc, or if a specific class is needed for using some specific feature?. I did do a search, and didnt find anything, maybe I missed it. Might be useful to have a thread regarding people's experiences..
Any suggestions/recommendations for what I should be looking at?
I have read that the Partiot/Adata/Wintec cards are not too reliable, though their prices for a class 10 are much lower..But I dont want to go through the hassle of returning/copying data, so I am thinking Class 4 is enough.
Here is one option, Sandisk 32g, doesnt say class 4, but some reviewers mention it is actually class 4. At the same time, some mention they got Class 2. Cannot post a link since I don't have 8 posts yet
Search for SDSDQ-032G-A11M, US Retail Package on Amazon, maybe someone else can add the link! Its for ~62, shipped from Amazon.
Thanks for your help!

This is what I bought.
http://www.newegg.com/Product/Product.aspx?Item=N82E16820220546
The nice 32gb ones were to expensive for me. This is a good price for it. i have been using for about a month and half. No issues at all.

Thanks cableguychad!
Anyone else have suggestions?
Thanks in advance!

I'm rocking the Patriot LX series 16gb as well. Class 10 and with transfers(usually 3-5 gigs) I'm hovering around 8-9mb/s.
EDIT: If you live by a Frys Electronics, I picked mine up there for $32.

I have the Patriot 8 GB Class 10 from FRYS. I'm getting speeds of ~11 Mbps.
I think it would be better to go with a 16 GB class 10 (~30 for Patriot class 10), than a 32 GB that's close to three times the cost of a 16 GB.

I just got this one, so far it seems to perform well enough. It's only a class 6 and it was writing at about 8-9 megs. Not too bad IMO.

You can't go wrong with this one. Great deal.
Many of my buddies have had 32GB MicroSD cards and a lot have malfunctioned. Never really had issues with 2-16GB MicroSD

Dont get HP brand, I had a hell of a time making a gold card because it kept getting corrupted. Format took forever to do as well.

Thanks for all your suggestions!

I took the 16g card out of my Epic and it works great its a class 2 I formatted it 1st and no problems. So it seems Samsung cards are good.

i bought a Wintech 16GB class 10 off newegg for $28. Out of curiosity, will the format SD card function in clockwork recovery work to just format it so I can use it? Or should I do a full format on a pc, why do you need to format before use? Why cant you just pop it in and go? Does HTC format the sd card before they ship all these phones to the carriers/customers? Just curious, thanks for input.

I've recently been having a great experience using Kingston 8 gig class 4 cards to record hd video.
To check the card speeds on pc I use CrystalDiskMark 3.
There is also an android app called SDTools that will show card information.
I also use SD Formatter 3 from sdcard.org to format my cards.

Another tool to find out if your cards are what they claim to be is H2testw. It checks capacities, corruption and read/write speeds.

Just an update, got the card in the mail, so far so good, dont know any way to test the speeds but i tryed two apps, one said it maxed out at 20mbs and the other 14mbs, so i dunno how acurate thise numbers are but all seems well!

Just pop it into computer, and format it as FAT 32, and use it. Generally all cards are pre-formatted when manufacturer sends u out. But I reformat it before first use to make sure its in the FS as per my preferences .

I bought a cheap 16gb card on ebay
I'm sure it's a counterfeit Sandisk. I've had it at least a year. I only paid twenty bucks for it back when 16gb cards were 50 bucks. It's only class 2. I used it for a long time with my Tilt 2 without any problems, even though I store 10gb of music on it. Now I'm using it in my Inspire. I tested it using the SD tools app. The write speed is 11.6 and the read speed is 20.4. Sometimes those numbers fluctuate slightly, but that's what it tested just now. It does fine with HD video. About once a week I was getting a disk error on my phone in which the card was becoming unmounted, particularly when I would use google navigation. I used SDFormatter 3, the one mentioned in the post above, and I turned on "format size adjustment", and the error hasn't happened in a while. I appeciate the poster who mentioned the software. It seems to work better than the native Windows 7 formatter on my pc.
Here's a link to a 32gb class 4 for sell right now on ebay. http://cgi.ebay.com/32-GB-Micro-SD-...906?pt=LH_DefaultDomain_0&hash=item2564d3c83a
Cards with the exact same generic blue and white packaging are abundant on ebay today from 17 to 30 bucks. Most are receiving good reviews. I may take a gamble. You never know.
Update: Ha ha. I asked the above seller if the card had been tested for capacity and speed. The reply was "Card no is fake. It real." lol

i wanna 32
hi, i looking for a 32 gb, i saw a wintec 32 class 10 but heard alot of bad reviews. i bought a trancend 32gb online for $45, turned out it was a bad card. thank god for paypal, told them my problem, got a refund. now for father's day, i wanna 32gb any suggestions? thanks. btw, does the diff class speeds make a big diff? i mainly put music in it. thanks again.

32GB SD cards

Anyone using a 32GB SDHC card in their Fascinate? Just asking because there's one on sale on the Newegg Shell Shocker later today (check at 10AM pacific time). Wondering about speeds and such, and whether Class 10 is worth it (seems like if you want to fill such a big card, it'd be nice to have the faster write speeds of Class 10 but I've seen some reports of incompatibilities/problems with C10 devices).
I was just benchmarking the card that came in my Fascinate (which is supposedly Class 2) with SD Tools and I get 5-8MB/s writes and 16-18MB/s reads which is way better than the Class 2 minimums. The one on the shell shocker is a Class 4 so I'm just wondering whether it'll be a downgrade in terms of speed (just because it's rated for significantly lower speeds than what I'm getting with the internal one). I'll probably end up getting it anyway because I've got ~1GB free on my current one and I want to play with an Ubuntu chroot install.

i got the sandisk 32g class 10 it was worth it. Seems to R/W faster but that maybe due to the SD card boost read ahead cache hack. I think mine is set to 512K. Whether its faster or not the extra space is always a plus

Guess ill find out the hard way with ya, bought one as well. Was also wandering about the speed difference. Noticed the one that came with was class 2 and the 32 was class 4, hoped it at least wouldn't be any worse as i am content with the speed of the included sd. Was really surprised to see that it was a class 2.
Oh well just have to wait until it gets here and see.

DO NOT BUY THE Patriot LX Class 10 32GB CARD!!!
After a few months of light usage (i hardly ever connected it to transfer anything, just had HD seasons of breaking bad, chuck, human target and sparta that I never had time to finish watching) I finally hooked it up for maybe the 6th time since i purchased it, and after transferring some music and more shows, i got a "Damaged SD Card" error. For the last month since that occurrence, I have had to reformat the card at least once a week, and set up my music and just a few episodes at a time (because whats the point of putting seasons on if i'll just have to transfer them over again in a few days) consistently. Sure, it moves along at 12MB/s, but certainly not worth the hassle.
This is not an issue that I have heard of with Class 2 or Class 4 32GB micro SDHC cards, and Patriot says they are working with Microsoft and Google to determine the cause of the issue, but Newegg reviews indicate that this is not an isolated incident.
Good luck with the SanDisk card!!!

Mhm, I got the A-Data 32GB class 4 from Newegg. I benchmarked it and it's not as amazing as the built in card (around 5-6MB/s write and 12MB/s read) but it's not super slow. Yeah, I ended up avoiding the Class 10 cards for that reason actually. It's nice to have so much free space now; I think I'm going to try installing Ubuntu in a chroot jail again.

The new PNY class 10 for tablets is now in stock at Newegg, just ordered one with free shipping.

I got this exact card -- Just arrived yesterday.. I am getting AWFUL performance from it. I mean it performed like 3MB/s write and 8MB/s read.. It only fluxuated by about +-1MB with various SD read_ahead changes.. So disappointed. The worst thing is my phone is NOTICEABLY worse-off with the card in (weird stutters, etc).
Which leads me to something else altogether -- Has anyone noticed that with no SD card in the phone it just flies? I mean even the old SD card which didn't SEEM to give me any stutters was a matter of night and day with it in our out.

Patriot has a lifetime manufacturer warranty on most of their memory. You should contact them about getting a replacement. I run their RAM on my custom built personal pc. It is super stable. Just hoping to help.

i was just about to buy a larger card when stumbling onto this post.
Does the read/write speed slow down as the card gets bigger in size?

No, but I have found that cheaper/nonbranded cards tend to be slower. Read reviews before buying.

I've got a lexar 32gb class 10. It's absolutely terrible. It takes so long for pictures from the gallery to load after you take a picture for example. Anything using hte SD card is slow as molasses. Oddly every benchmark I throw at it shows high speeds, so I have no idea what is going on with it.

may be could try this (get rid the lba) could help the perfomance and compatibility ?
try read this thread (hope help), I'm not try it my self on my fasci, since my class 10 msd still on it's way send to me.

I'm using an adata 32gb class 10 card and it flies. Check on newegg for cards if you haven't already. The price seems to be dropping on these cards recently. What was once 120 dollars is down below the 100 mark or less!

I am running a 16 gig class 4 Sandisk card, and it runs well.
Played with the camera some, and recorded some video to test it out. Haven't had any problems there.
Also loaded some movies to the sdcard, and played them both on the device and through a video cable to a t.v., didn't see any issues so far - but I haven't had a lot of time to dig into it. Currently only tested .avi video using mobo player.
No problems transferring data back and forth through the device to the sdcard when plugging into the computer. Loads up right away as an external drive (windows machine), drag and drop, edit files on the device, etc... no problems.
I have a pny class 10 (8 gig) I could compare it to if you're interested, otherwise i'll get around to that eventually anyway.
Is there a god benchmark app to use on the device itself to compare memory cards?
(I know these card capacities are way below what you're asking, but I don't have any 32 gig cards to throw at the question yet - may be a while before I get any)

What's the cheapest place to buy cards? Usually I've bought from Amazon. I always have thought it was cheaper than Newegg. Thoughts?

I always trust Newegg with my SD cards. They have a good selection at good to very good prices and their customer service is Eggcellent! (sorry, I couldn't resist )
Everytime I've had an issue with any of their cards (only 2 times now), they promptly remedied the situation to my satisfaction.

I can most definitely say that the class 10 shows a significant speed difference on the phone then the class 2 and 4 cards i've been swapping in and out.
I'll be picking up some more class 10 cards from different manufacturers to do a speed comparison like I did with the Nook Color, but for the moment I feel completely safe in recommending a class 10 card over a lesser class.
On the Nook Color, we were running CM7 from the MicroSD card itself, and learned that the operating system depends on small-block read/write moreso then large-block read/write in order to run well.
It was hard, at first, to figure out what was making a difference, but after tons of people posted up test results using a specific benchmark software we narrowed it down to SanDisk brand cards, specifically the class 2/4 cards in the largest capacity you could find as the winners of quality.
All other manufacturers were focusing on large-block read/write speeds to use as their metric for quality, while SanDisk paid extra attention to small-block read/write to give a balanced card.
This made a lot of sense from a general manufacturing standpoint for the majority of businesses out there. Digital cameras/camcorders and file storage were the main usage of flash memory cards - and that kind of stuff is all large chunks of data. Streaming video, transferring large files or groups of pictures has little to nothing to do with small-block read/write.
When it became evident that SanDisk was the only manufacturer focusing on the actual specifications we needed to rely on to run an operating system from the flash memory card, the general recommendation became to say get a SanDisk over in the Nook Color forums here at XDA.
From the research i've done in that direction, carrying it forward here, i'm finding that small-block read/write has little impact on the proper running of this phone. We aren't running the operating system from the memory card, like we were there, and the information transferred back and forth is in greater chunks.
Generally speaking, and before I can conclusively state anything, PNY looks like they are going to be our recommendation here for this phone. I say this not to make that recommendation now, but to challenge people to prove that wrong.
PNY has built their business around speed based on large-block read/write capability for their flash memory. They were my general recommendation before my Nook Color experiences for that reason.
My class 10 PNY card (8 Gig) blows away everything else i've got in this phone so far. I've run a couple class 4 SanDisk (16 Gig) a class 2 SanDisk (16 Gig) and 5 different class 4 SanDisk (8 Gig) cards in this phone so far.
I don't have conclusive speed test data correlated from the phone yet, but it's coming. (There's a ton of stuff i'm testing all at once on this phone, I simply don't have time for it all even with the long days i'm putting into it)
Right now the new ROMS starting to filter out are getting put on my testing schedule, as well as constant video testing with as many televisions as I can come into contact with using several different cables. The GPS / A-GPS issue is my biggest front-and-center concern at the moment, and until that's hammered out to my satisfaction I won't be able to sit down and speed test the memory cards in the phone within a variable-controlled testing environment.
Give me a few weeks to get the rest of it worked out and i'll be able to sit down and make side-by-side speed test comparisons of all the cards I have, and that'll give me some time to get more cash together to get some decent class 10 cards to use in the testing.
Right now, my class 10 card seems to perform the best. Can anyone refute this, or substantiate it with their own results?

If you do get a 32GB, the Lexar 32GB Class 10 is an excellent choice. I've done extensive research before purchasing mine off of newegg ...
The card is solid and has impressive read/write speeds that can't be touched to date. If you google it, you should be able to find some comparisons as I did. (Note: It may not show up on the first page of results...I remember going through a lot and typing different words when researching...)
Advice: DO NOT BUY THE PIECE OF CRAP ONES OFF OF ?BAY. THOSE ARE PIECE OF JUNKS FROM CHINA AND MOST ALL FAKES. THEY ARE 2GB CARDS WITH A PROGRAM HACK TO HAVE IT READ AS 32GB. ANYTHING MADE IN CHINA, STAY AWAY. WE ALL KNOW THAT...
THE LEXAR IS REPUTABLE AND IS MADE IN KOREA, WHICH IS THE BEST OF THE BEST IN CHIP / MEMORY, PERIOD. WELL LCD'S TOO...
FYI: I'm not one to fall for second best when I could enjoy having the best of the best. Lexar 32GB Class 10 is the way to go.

don't get a 32g class 10 patriot card unless they fixed them
the one i got in january keeps corrupting data on my phones but no other devices.

Half the stuff in your home is prolly from China.
Anywayz, I know that the Class 10 cards actually do give better speeds. My question is does it matter for our phones? Is the SD card a bottleneck for the Doubleshot?

Yep, positively.
I had a PNY class 10 8-gig card, specifically advertised as "high speed data transfer" and it was.
I had a bunch of SanDisk class 4 - 8 gig cards, and some SanDisk class 4/2 - 16-gig cards laying around from the memory speed tests I did on the Nook Color.
Whereas the Nook Color requires manufacturing attention to small block read/write data paths, the MT4GS requires large block read/write data paths to be more robust on the physical circuitry of the card.
I restore half a dozen to a dozen CWM backups on my phone a day. There was a noticeable shortness in the time spent restoring a full backup from the class 10 PNY card.
What we learned last time, and the links are in the bottom line of my signature, is that SanDisk cards are ideal for the Nook Color, because that particular manufacturer makes a more balanced card. For the ( for now ) niche market of running an android installation from a MicroSD card, either you get a SanDisk card or you go home crying.
This phone, or any phone, is just the kind of device that the class 10 MicroSD cards are targeted at and made for. Large block read/write transfer applies to things like:
-Streaming media (movies, music)
-Playing media from the MicroSD card
-Playing most games, at least the higher-end graphics-wise ones.
-Transferring large chunks of data...like recovery images, folders of pictures, movies, etcetera and so on...
When the phone tries to grab stuff from the MicroSD card, it usually does so in large enough grabs where it falls into the category of large block file transfer.
I was trying to do memory tests on this phone with benchmarks that can be compared like the threads in my sig, but for the moment i'm too wrapped up in other stuff for this phone.
Until I can throw blocks of time at testing, and only testing in one sitting I can't control the variables I can influence enough to validate my results to myself, let alone to share here. Meanwhile, i'm keeping an eye on this thread, so keep asking questions and experimenting!

Nice, Blue! I'm going to pick up a class 10. I am specifically wondering about gallery rendering. I use my MT4GS for looooooooots of photos and videos. I open the gallery constantly and it takes a while to pull all of the content. I currently have a 32gb class 4. I'll report back my findings.

Yep, you'll notice a sizeable difference going from a class 4 to 10, even though you didn't mention the manufacturer.
I really, really wanted to use the stock gingerbread gallery from Google, but it's just not as good with loading pictures as the stock HTC gallery is.
I've compared them both using the same memory cards, and while the Google gallery is good using a class 10 card (PNY in my case, 8 gig) anything less and it won't load all the pictures the first, second, or even third time you kick it up.
I like the Google gallery better, because it means I can eliminate the sense frameworks altogether on the MT4GS, but it just can't compare to how well and correctly the sense gallery works.
Shame, looks like i'm stuck with sense, but i've not been loading anywhere near the number of pictures you are talking about.
I am eagerly awaiting whatever results you care to share moving up to a 32G class 10 card - let me know what manufacturer you end up going with.
I want one, but it's just so hard for me to justify the cost of it against other things I have to spend my money on, since I have about a dozen MicroSD cards here sitting in front of me.
I just broke my class 10 PNY card yesterday - pulled the cord from the pc before it said ready to eject, while it was trying to make it ready to eject. Now the card won't format in any device or compter I put it in - dammit.
Maybe I can convince myself to buy one if it seems like it made a drastic difference to you, since I don't have any class 10 cards left now.

It all depends on what card you get. I recommend both 32GB cards in my signature.

I have a pny 32gb class 10. $50 at bestbuy few weeks ago. So fare i have no lag or issue.

LEXAR 32GB class 10. My QuickPic gallery opens up instantly. Load times are negligible. The photos are just there! I moved up from a SanDisk 32gb class 4.
SD Tools measures it as writing at 10MB/sec.

I wanted a balanced card for everyday moderate use. Based on Blue6IX's comment in post # 14, I decided to go for SanDisk. Observing that the MT4GS came with a SanDisk Class 4 card and the speed was sufficient for my moderate use, I just upgraded the size with a 32GB SanDisk Class 4 card.

Since I changed my signature, I'm running a Wintec 32GB class 10 card in my Doubleshot and an ADATA 32GB class 4 card in my Vision. Both cards run pretty well, especially since I have the real A2SD running in the Vision.
I also recommend PNY's cards. Best Buy has those on the shelves if you don't want to wait for UPS to deliver it.

I just ordered a 64GB card from Sandisk. It's supposed to come in Tuesday. If it works I'll post back here.
