Hi. I recently purchased an Epic, upgrading from my EVO. I like that it has a 16GB card preinstalled. However, I notice that its only a class 2.
I'd like to properly store and run some apps off my card, and I'd like to get a faster card, say a class 6. What's a good brand for SD cards? If you know any sites with some great deals on class 6 16GB cards, please let me know. Thanks.
Usually newegg has some good deals
Don't pay attention to the class rating.The class 2 part means that it has a minimum speed of 2MB/s. Realistically, it should perform much faster than that. My read speeds (with my Epic in mass storage mode) are around 10 MB/s and my writes are between 3-7 MB/s.
Unless you really notice your apps are lagging when loading off the SD card, there's no need to buy a new card just for the class rating. If you do get a new MicroSD, be sure to get a bigger one, not just a theoretically faster one.
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

They also have the Patriot Class 4 might just go with that 30 cheaper....
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!

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.

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.
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.

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.

ordered the sensation today and wanna ask first how is the card that comes with the device? are people using it or most of you bought a new one?
2nd, which card would you recommend?
It's not a bad card, 8gb class 4 so it's fast enough for most everything. What is too bad is that the phones doesn't have more built in memory. I can fill 8gb fast so for me, a 16 GB card is minimum and the higher the class the better imho.
There are a lot of cards out there, I would recommend a name brand unit and at least class 6. I've got a 32gb class 10 from newegg and it works great (cant find link right now).

Newegg has the ADATA 16GB Class 10 card for $25 right now. I bought it for $35 when I got my phone last month & I thought even that price was worth it
Try not to buy anything that are related to storage on ebay or online in general, e.g. microsd card, external harddrive, usb stick...they tend to be always fake. Best to go to local stores with good reputation for these things.
I bought a Lexar 32GB class 10 microSDHC card.
17 MB/sec read
8 MB/sec write
this was using SD tool for android.
I am hoping that once S-OFF is achieved, and we get cyanogen running on this device, the speeds will improve. The card cost me about $90 shipped, and came with a USB to microSDHC adapter. At this point I am very disapointed in the card's performance. Even when using my computer to transfer the data to it, the best I got was about 8 MB/sec write.
Also after a full format on Windows 7, the card only shows 29.8 GB capacity
though the detailed figure was 32,005,685,248 Bytes
I am hoping this card is not a fake. Can anyone else confirm their benchmarks with a 32 GB lexar class 10?
locate a Lexar 16gb class 6 from a reputable dealer.
can be had for around $20.
I get around 7-9mb write and around 17-20mb read speed.
seems like about the same speed as the class 10 Lexar above.
32gb version is too expensive still. don't understand why they cost almost 5 times more when the capacity is only double.

Your capacity is correct. The difference is due to the fact that a properly calculated byte, kilobyte, megabyte, gigabyte, or terabyte is calculated in base-2. The manufacturers have long been in the habit of calculating in base-10, hence the difference in what's claimed and what you actually see.

I think it might be a bit much to imply that any online vendor should be avoided when purchasing flash memory. As long as it's from a reputable vendor (not a ebay seller or amazon seller), you should be OK and in the event that you end up with a fake you would be protected by the vendor's return policy.

Like white i purchased a lexar 32gb class 10 card. Although transferring to the card was slower than claimed from my hard drive but transferring from my old micro sd to the new one i recieved much higher speeds with a class 6 limit due to the old card.

why cant you transfer more than 4gb file onto the card?
sorry for not being specific. You cant transfer more than a 4gb file because that's the limit for a fat32 microsd.... i believe.. lol
Yep, fat32 has a file size limit of 4Gb.
now i doubt there will be any difference between sd cards. We need a2sd or d2sd in order to evaluate better. On the HD2 there was a major difference between class 2 and a class 6 card. On the sensation i have tried class 2 and class 6 the performance seems the same.
