micro sd memory card class

i know that there are different classes of cards: 2, 4, or 6 but what are the main idifferences and will it effect my phone in anyway if i get a 2 compaired to 6?

Heard that Class 4 is the optimum for the Nexus one...anything more than class 4 it wont make a lotta difference.

I can tell you I have an 8g Sandisk Class2 and an 8g Transcend Class6. The Sandisk blew it away in speed comparisons. Not all SDs are equal. I wouldn't have believed it but I tested it myself. Yo have to have root and adb but there is a speedtest on Cyanogen's forums. I tested each 3 times and averaged. The Sandisk was faster by a considerable amount. I also think the Class4 would be optimal and would spend a bit extra on the Sandisk.

I just got a 16gb Patriot Class 2 to replace the 4gb Class 2 stock sd card. My response the first time I opened Gallery "OMFG HOLY CRAP". Instead of the typical 3-5 second load I am at about .5-1 second. Write speed is amazing. This card is just fan-damn-tastic.
I can say I tried a Class 6 16gb off-brand prior to this (my dog ate it) and it had none of the characteristics of this current card.
So for my money, before you consider Class, consider Brand / Quality. The better quality cards will always outperform the lesser cards. If you are worried about the Class (transfer/write speed) then get a good brand and higher class...but for me, the Class 2 Patriot is amazeballs.

hhmm, never heard of Patriot.
I've used SanDisk and Transcend before.
My current one is the stock one that came with the phone.
However, with your "OMFG HOLY CRAP" emotional outburst I'm thinking of researching that brand

I really want a 32 gb microsd card for the n1. Yeah I know its kinda overkill but it would be my card for life really. I just wish there would be a day when I could walk into a best buy and pick one up.

i used patriot ram in my computers, good brand, didnt know they made sd cards, i think ill grab one, right now i have 4gb scandisk class6 seems fast and smooth

I have this one coming...

I have no idea if there will be anything worth forking out over for a class 10 card but since my wife has been belly-aching for speedier storage in her video camera I figure I got nothing to lose. Doesn't wow me in the phone it can find a home in her camera. Somebodies got to take one for the team....

They will come. In fact, a webshop here home has put it up for pre-sale allready and has a unconfirmed arrival date June 1st.
price will be here $180 dollars +/-. But will be way cheaper in the states.

(site is in Norwegian)

The thing that bothers me about Sandisk (besides the price) is even on their own website they don't list what speed class the cards are. On Amazon I can only find class 2 cards. What's up with that? Maybe class 2 would be enough but I'd be more comfortable with class 4 or 6. Do they even make them in that speed?

I want one too, but not at their current going rate of $200.
I'll probably end up picking up a 16gb one soon since the 32gb ones aren't in any hurry to get cheaper.

On amazons search I typed in 16 GB class 6 micro SD and it pulled some up along with a passel of other sd cards.

The class # classification has merit behind it. But unfortunately cheap manafacturers are abusing the system.
I bought a sandisk 16gb class 2 card not too many weeks after it appeared on the market as the first 16gb card. Never have i wanted for more speed. Songs load up instantly in the music player and the gallery has no lag at all. Don't fall victim to high class # claims. Just go with a manufacturer that you know and trust. For me that's sandisk.

im already sending back my first class 10 card.bought it from newegg but had to get kingston to replace.had problem with corrupt data and making my nexus go loopy.kingston replaced it without any hassles.

hey guys i stay in dubai and i have searched the computer vendors and they only have sandisk class 2 cards and nokia's class 4 cards so if i buy nokia's class 4 mu 44 will it function properly if i want to install app2sd?

Not sure why i cant find it on the bestbuy website but i know its still there at the store bc i seen them there again just a few days ago, i bought mine a few months ago but anyways i found a PNY 4 gig class 6 HC-->high capacity i think, its in the camera section and sells in the black and red pack, not the black and gold one they also have. I bought mine regular price $22.99 which isnt too bad for not buying it on the web. It made my G1 songs and pics load blazing fast and ive since replaced my stock nexus card and have noticed a night and day difference on certain things pertaining to sd. just thought id share what i thought was a good deal. Later, veritas
also wanted to add that ive prolly reformated with parted literally between 100-175 times and really no slower rates on anything and barely a smidge shaved off the top

Sandisk 16Gb MicroSD Class 2 - £20 delivered

Just bought one of these from 7dayshop. Decent speeds according to these gadgies.

BS...

Now... If they'd only ship to Finland.

for some reason that still seems expensive to me
i can find faster 16GB card for less

And they are sandisk, and not some cheap one's which won't do over 9MB/s?

the first 2 brands are actually better and faster for less than Sandisk
yes sandisk is sandisk, they are always expensive

Can someone please elaborate on this class thing? I noticed that Toshiba SD class has different ranks, but none of the sandisk cards I find says anything about read write speed. Thanks.

Depending on the class, that's how fast the write transfer is I think. Class 2 = 2mbps, Class 6 = 6mbps. I don't think that's the literal translation though, better wikipedia it up.
I personally will find it very difficult to use a 16GB Class 2 card since I do a lot of transferring between computer and phone. I transfer videos, music, comics, and very nice photos.

Is there any way to tell the class from the package of a sandisk micro SD card? I have read plenty of stories about how people ordered a class 6 SD card online, only to find that it is actually a class 2.

on real authentic ones it's printed on the package inside the sealed plastic, also in the card itself
specially any model that is Class 4 or better
if it's not marked on the SD card then it's a Class 2

ah I see. Thanks.

anywhere in particular, Im in brampton and would like a 16GB card for cheap, canadacomputer has one for 44$ but maybe you know somewhere for cheaper? Would it make sense to buy two faster 8GB cards and hide one under the back cover somehow? (im sure a card is thin enough to fit under there no problem?)

Better SD buy !!

megabitpersecond !!!! you mean megabytepersecond
mbps =megabit
mB =megabyte
Class 6 = 6 megabyte
So you are wrong 8 times

I have a 16 gb class 2 sandisk in my phone and i have seen white speeds up to at least 5 MB/s. So i am wery satisfied with card.

Does the class only affect speed when copying files, or does it matter when using apps and such, watching videos, viewing photos? I ask because Class 6 is really expensive in my country

Is it possible to get 32gb c4?

Yea i'm wondering about that two. I don't really care about speed regarding copying files from pc to phone, but i would be worried about watching videos and lags and and all.

As far as I know it is only write speed. Meaning when you copy data TO your card, read speed on my card is a lot faster then write speed.
But that also means that if you record 720p video to your sd card it matters if your card is fast enough...
But just get yourself a SANDISK CLASS 2. as I said I have no problems with speed of that card..

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..
Sent from my T-Mobile myTouch 3G Slide using XDA App

I am looking at getting the. A-Data micro SDHC 16gb Class 6..from compusa if that helps
Sent from my T-Mobile myTouch 3G Slide using XDA App

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...
/whistles

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.

which SD card to get?

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).

http://feedback.ebay.com/ws/eBayISA...sspagename=VIP:feedback&ftab=FeedbackAsSeller
good enough? or too much?

That's a link to the seller's feedback so I don't know what item you were looking at. Feedback seems good though.

You need a micro sd. That link is the wrong one.

ok i give up.. can anyone recommend me on a good and not expensive 16gb card?

I brought a 16gig pny card, its been very good so far.

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.

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?

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.

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 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. As for onlkne vendors i have purchased all my external/internal and sd cards from ebay. I have had 1 problem but that was my fault because the offered price was too good to be true

hmm i read an article on the main xda page about microsd cards.. it says the sandisk one has better i/o and random reads and writes.. so now im really lost..well in the end.. u still cant transfer more than 4gb file onto your microsd 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.
