I recently purchased several MicroSD cards from eBay, all of which came from places in Asia, for less than $10 each.
When they arrived, I began testing them to see how well they would perform. I wrote zeros to the MicroSD cards and found the performance to be that of a class 2 card. The card was supposed to be a class 10.
I got 3.7 MB/s writing speed, with around 6.5 MB/s reading speed.
The card is recognized by my computer as a 34 GB MicroSD, with nearly 32 GB available.
Unfortunately the sellers don't seem to be taking responsibility for selling slow cards, because when contacted, they all want to do a half refund, insist that I received a defective card, and it would cause them major losses to resend a class 10.
I put one card in my netbook so I could have 32 GB of swap, and I've managed to compile CyanogenMod, when I previously could not
I hope this sheds some light on the current status of the generic class 10 32 GB MicroSDs found on eBay
thanks for the info, i currently have a PNY 32gb class4. would it really be worth it to get a legitimate class 8 or higher. is android even capable of matching the possible speeds?

Most phones or tablets should be able to use the full speed, unless it's a very cheap phone or tablet.
If someone is trying to sell you a class 8, I'd be a bit skeptical, as there is no class 8.

Thanks for good news.
But the delivery needs a long time to my home if i buy it on ebay.
The local purchase may be faster.
I never pay attention to these problems, read this topic I know there are these problems.
works fine but sandisk ultra crashed after, card problem though
A mi me va muy bien.

Any recommendations for a microSDHC card? I'd like a 16GB. I've been reading up on Class 2, 4, 6, and 10 cards. The consensus seems to be that Class 2 is adequate for most phone usage, except perhaps for recording 720p video.
Any thoughts on this? Brands? I'd like to grab a SanDisk from Office Depot for about $32.
I got an 8gb class 6 for $20 (search newegg for item N82E16820208453 i cant post urls yet sorry).
I figure I may be able to use it in other gadgets in the future and it was only a few dollars difference from a class 4 or 2.
An 8 GB doesn't seem such a bad idea for a starter. I have an 8 GB iPhone 3G right now, and I'm trading it to my daughter for her iPod Touch 8 GB. I'll use it for podcasts and music I don't listen to much.
I'll probably trade up to a 32 GB when they come down in price, and maybe in the meantime I'll grab another 8 GB as a backup / extra "film roll" for trips.
Class 10 is meant for super fast write speeds needed for higher end video capture and the like. Usually DSLRs and such. You'll see a significant price difference for class 6 and class 10 cards. I doubt the Aria camera and system really needs, or even can take advantage of those speeds. Best bet is any basic card I suspect. I prefer going authentic Sandisk >=8Gb. I've been burned recently by DOA Polaroid labeled cards so I'm going back to Sandisk from here on out myself.
I ordered a Class 6 Transcend 8 GB card off of NewEgg. I wanted a Class 6 16 GB, but one comment in the reviews scared me away from the Transcend 16 GB card:
Pros: Reasonable price, good transfer rates.
Cons: When trying to partition ext2 anywhere besides partition slot 1 it returns:
"ERROR: input/output error during write on /dev/block/mmcblk0"
Makes it so you cannot use apps2sd for Android.

I wasn't sure if this would apply, but I didn't want to risk it. The 8 GB reviews all said it worked fine with Android phones.
The 8GB card was only $20, and I figured that I can probably deal with that until the 32 GB cards come down in price. Also, the 8 GB card was a 5x Customer Choice Award Winner, with 624 reviews. Since my iPhone was 8GB, I'm pretty sure I can live with that for awhile, maybe getting a second one to take on trips.
I personally like A-Data, Transcend, and Kingston. I've had compatibility problems with Sandisk before. I like these brands because they've never given me compatibility problems. I've bought a lot of cards from Transcend, but recently, I'm leaning more towards A-Data because their cards are generally pretty fast, like this one.

I got a 16GB card from Sandisk on Newegg for cheap, slapped it in there and it worked perfect. It is a SDHC card also but so far no issues at all.

I got a 16gb microSD class 2 from frys for $17.99 after mail in rebate sounds like a good deal to me. The brand is polaroid by pny, but who cares about the brand.
Sent from my HTC Aria
I've been using the stock card, but used an A-Data 16gig class 6 to root the phone. I'm planning on buying another one to use in the phone. Class 6 may be a little overkill, but i use it in my helmet cam, and i'd like to keep a spare one around. i doubt i can fill 16 gig on the phone.
Bunnie Huang of xbox hacking and chumby fame has done a forensic analysis of a handful of microSD cards in the pursuit of the best quality to include with the chumby device. He determined, among other things, that:
"Kingston is revealed as simply a vendor that re-marks other people’s chips in its own packaging. Every Kingston card surprisingly had a Sandisk/Toshiba memory chip inside, and the only variance or “value add” that could be found is in the selection of the controller chip."
The article is an amazing read.

You'll fill it up quickly if you load all your music on it. Personally, I'm looking forward to when 32GB MicroSD cards are more widely available and the prices are a bit more reasonable.
I picked up a class 2 16gb Polaroid from fry's and I've had no problems. Usually I would never go for that brand (usually go with Kingston or patriot) but the price was good at 25 bucks. Have had no problems whatsoever with it.

I got the same card at Frys on Sunday, great deal! If you look closely at the labeling it says made by PNY for Polaroid.
I have a HTC Desire and im after a larger storage than 4gb included.
I'm a bit wary of class 2 cards in fear they will be very slow. And I'm also wary of fake cards on ebay for example.
Also does class 4 vs 6 make a large difference?
I want a 32gb if its the right price (and not class 2?) but im not sure where to buy from. The site must be able to ship to new zealand.
Thanks.
I know that Verizon is supposed to be selling 32GB microSD cards, not sure about the class but I don't think their class 2. There normally $150 but have been on sale for $99 at least 1 or 2 times. So even if it is a class 2, still better than the $199 price for the Sandisk 32gb one on Amazon. Either way good luck, I hope you find the card your looking for!

lol. that is regular sd card not micro sd.
There is not a 32gb class 6 micro sd card on the market as of today.
Yeah, class 4 is about twice as fast as class 2 cards. I would say the best price/speed ratio right now is the Kingston 16GB Class 4 MicroSD card. Best places to buy micro sd cards online would be Amazon and Newegg. There's hardly any bull**** with the products on those 2 sites.
Amazon UK - You've now got 32 gb class 6 micro sdhc at £88.00 link class 4 at £85 link . I just ordered a class 2 for £64.49 including postage - link
Hope it helps.
Uhmm, a bit of confusion in my mind, wich class is enought for my Galaxy S?
The 'class' rating on the card can basically be thought of as the tested minimum transfer speed (sustained - not random. A random write can far exceed the class rating).
class 2 (~1Mb /s)
class 4 (~2Mb /s)
class 6 (~3Mb /s)
and the highest I've seen is class 10 (~4Mb /s) which I doubt any of us are going to buy.
So far as I know, there is NO CLASS 8 - don't buy one, it's probably a fake. By the way those ratings are in mega bytes not mega bits if you need the bit speed just multiply by 8.
Now if you're ever told 2 is faster than 4 you can laugh in their face - when (dealing with technology) has a lower number ever been better???

I meant to answer this earlier but any class would be more than enough for the galaxy s. The reason you want a higher transfer speed is that loading 8, 16, or 32 GB of data can take forever depending on the type and amount of data. As far as the phone is concerned, a class 2 is fast enough for a swap file, video/movie, or music.

Hey gang. I am new here. I just purchased a 32gb card class 2 for my Samsung Vibrant. I noticed it handles just about everything except recording hd video directly to the card. The first few seconds during playback show as rainbow colored garbled pixels then clears up to play clearly. Reduce the recording resolution of the video and it plays fine. Record hd video to phone then transfer to card and it plays fine. It is a brand new card (kingston) with next to no data on it so far. Anyone else having this issue? I am thinking I need a card with a higher class rating.....

To record HD video smoothly you are gonna need at-least a class 4 and maybe a class 6. Class 2 doesnt write fast enough to keep up, thats why you had the pixelation distortion.
As far as a 32gb class 6 card, I am afraid we are out of luck until these cards come onto the market. Samsung has been working on a new card I heard.
Hoever, newegg does have class 4 cards in 32 gb for around 100 bucks.
Hope this helps.
UPDATE
there is a class 6 32 gig card I found at amazon but it is a "Komputerbay" brand so buyer beware.

If I am not mistaken, that is a standard SDHC, and not the micro SDHC that our phones require.

There are a couple of off-brand class 6 cards that have shown up on ebay and Amazon called TopRam and 3C Pro. Anyone have experience with these?
I am familiar with the usual suspects (i.e. Sandisk, Kingston, Patriot, A-Data, etc). but was wondering if there have been any positive reviews with the ones above since then do tend to run substantially cheaper.

If you're lucky to have Micro Center stores in your area, their house brand 16GB microSD card is not bad at all. For $34, you get a card marked as class 2. But I've tested mine on my PC and its write speed is around 7 MB/s and read speed is around 14 MB/s, practically a class 6 card! No wonder this card always seems to be out of stock quick.

i know what class means. There have seen a few reviews stating 6+ writing. Sandisk is about as as good a quality chip that you can get so paying less and getting quality is a win win.

I tried my luck with a TopRam 16 GB class 4, and I have transferred a little over 8 gb of files onto it and use it daily with no complaints.
I purchased mine on Buy.com because it was a little cheaper there a few months ago when I ordered it.
Found this on Ebay, don't know though. It comes out of Shanghai and the price is cheap. I'm more worried about cheap crap wrecking my phone. Anybody try one of these yet?
http://cgi.ebay.com/SanDisk-32GB-mi...gital_Camera_Memory_Cards&hash=item1e5e54d767
it won't wreck your phone, but it will probably die after a few weeks - if that long. If you but it, be prepared to throw away your money at some point and all the data on the card.
SanDisk probably won't warranty it because it is probably counterfeit.
don't think u ever will get it
last 16gb card i bought over ebay was about 7€cheaper then all the rest and i never saw it - got money back by paypal thats why i tried (and he had about 100 positive votings).
this seems to be about 50€ cheaper then a normal 32GB card and he has 0 votings - so he propably tires to get the money and vanish into dust before Paypal can claim the money from him.
would buy something more recent.
I bought a 16gb kingston class 4 on amazon, it was around 45$, and they had a promo that if you signed up for an amazon credit card you get 30$ off your first bill. so bought it and paid it off for 15$.
Honestly, with Froyo coming soon and apps2sd, Id really reccomend investing in a good class 4 or 6. The faster the speed of the card, the faster your phone will be able to pull and push data to it.
Another note, my class 4 can move large files at about 8-9 mb/s, but if there are many small files it will only run about 3 mb/s, so Id really recommend a reputable brand. That is not to say the kingston doesnt work good, just to say one of those cheapo 30$ cards advertising class 6 will probably run much slower and break apart quickly
Good point about the speed issue. Can't wait for Froyo.

Class ratings apply to write speeds not read speeds. Theoretically you can write faster to higher class cards, but this usually applies to direct writes on the device (camcorder recording to card) not USB between phone and PC. The USB copies (PC to phone) may be faster, but you have a additional overhead of the USB bus.
Buy a name brand card. I have an 8Gb Sandisk class 2 and it works great for Camera, camcorder, and anything else i want to do with the phone software. My 1080P camcorder has class 6 cards, but it requires it.
I'd steer clear from buying memory cards/ usb flash drives on eBay. I've seen way too many people get scammed on getting what they thought was a 16gb flash drive and end up with a 128mb stick with 16gb screenprinted on it. These microSD's are no different.

Actually I tested this using the sdhc adapter directly to the SD card slot. so no USB/phone interface interfering here. And again, thats what I was stressing. Buy a name brand card, probably a class 4 or 6 considering the move to froyo.

So you got the same MB/s throughput with the card reader as well as the phone connected to the PC? Still puts the USB bus in the way. EDIT - NM I see what you were measuring.
I wonder what the transfer rate is on the phone - back and forth between internal SD and external SD.
Huh, interesting concept. I dont even know of a way to test that
I bought a 32gig card from China for 18 bucks shipped. 1st time I've been scammed on ebay. It seemed to show up as a 32gig, but the phone wouldn't recognize it and wanted to format it....sure thing I figured. Now it shows as an 8mb card that won't format no matter what I do. I disputed it to paypal after the auction/seller disappeared on ebay, but they want me to send it back to China to refund. I considered this might happen and was willing to risk 20 bucks, but it didn't end up well. The funniest part was that it showed up in Kingston packaging, but the date was 2008. I'm pretty sure 32 gig microSD's didn't even exist in 2008.
Thats terrible!! well good luck getting your money back... Lol so I guess if it looks too good to be true, it probably is. Id just stick with trustworthy sellers, brands, and sites, and look for good deals!

Many people are using 32GB cards. It is the limit of the SDHC spec, so the 16gb is probably a typo from somewhere.

I browsed through amazon's selection and found many bad reviews regarding data loss on several products. What brands are generally known for reliable SD cards? Sandisk seems to make good cards?
And another thing, I read that often SD cards are faster than their class. There were people that got transfer rates of up to 15 mb/s with a class 2 card. Apparently a class 2 card is basically the same as a class 6 card, just that in the latter case the manufacturer guarantees the higher speed while in the former it might be slower. Is that true?
As for brands, I recommend SanDisk and Lexar. I've used cards from both manufacturors in all my cameras and phones for years, and I've never had a card fail me.
I got 2 Lexar in camera + phone : no problems so far
+1 for SanDisk
The Speed Class Rating is the official unit of speed measurement for SD Cards, defined by the SD Association. The Class number represents a multiple of 8 Mb/s (1 MB/s), and meets the least sustained write speeds for a card in a fragmented state.

If I understand it write, the class rating is a sustained speed, so you may get faster speeds, but usually not.
Also from that same site, manufactures quote speeds, and not an independent testing company, so they may not always be honest XD
Secondly, Sandisk for 16 gig never gave me a problem. However, at 8 and 4 gig pny hasn't given me any issues either.
i wanted a bigger card a month ago and looked at both lexar and sandisk 16gb, i went for the lexar as it was apparently faster in the reviews and was only a tiny bit more expensive than the sandisk. and it has been perfectly reliable.
Ok, thanks.
joememe, which reviews did you read? I found one lexar vs sandisk at nokiaguide.com and just want to make sure we don't both base on the same review.
Because if lexar really is better I'll spend the few extra €.

That's interesting and a good thing because standards like S-ATA 1/2/3, USB 1/2/3 and many others define the max possible transfer which isn't very userfriendly.
So I suspect that all cards of a manufacturer are essentially the same and get a class 4/6/10 rating after production according to their QA results. Like with a CPU you might get lucky and the card just barely didn't make it to 10 and thus get a very good performance class 6 card.
I ordered a 16gb class10 Transcend card from Newegg and LOVE it. Lifetime warranty ftw!! I've tried returning Sandisk cards for warranty and haven't received a response in months...so not +1 for Sandisk if there are warranty problems.
I just picked up a Transcend 4gb class 6 micro sd from Newegg and it died within a day. Luckily Newegg is shipping out a replacement asap and I don't have to return the defective card.
+1 for lexar 16gb class 6
Here's a link to the one I use. I own 8 or so of these and use them in cell phones, camera's, and even in a cam corder. I have yet to see one of them fail or have any sort of performance issues.
SanDisk 16 GB Class 2 microSDHC Flash Memory Card
Note that even though it's a class 2, in my testing with each of the cards I own, I have consistently gotten class 4 performance from all of them.
If you want something even bigger, the 32 GB cards have really come down in price. Here's a SanDisk for $71.
SanDisk 32GB MicroSDHC Card (SDSDQ-032G-A11M, US Retail Package)
Isn't the price a bit too low? The one on Amazon has a bad review saying it didn't come in the retail package.

IMO, Sandisk is definitely the best choice for a quality microSD. They always perform much better than their class rating. And the also are most consistent in getting good randon read, write and access speeds, which is much more important that the class rating when using the card in cell phones or for any task other than just large data transfer and digital cameras. Higher class cards only give higher sequential write speed, but usually are worse at random read/write speeds and access time than a class 2 or 4.
