Ebay put out an article to watch out for fake sd cards. Too bad you missed it.

I went with the 32gig class 10 lexar on amazon. Works great, amazingly fast transfer speeds!
Have you run SD Tools with that? I'd be interested in the results.
I agree, I'm very interested to seeing a benchmark of it in action!

Thanks for the post. Saved me from buying :3
Glad I helped someone else out!

Hey you saw how my 16GB card did and that was a "class 2"

i'm not complaining at that price, considering i have about 4 of the 16gb cards that the phone ships with
Yeah, I am going to have to sell the 16GB that came with my Epic haha

I paid $99 for my 32GB class 2 SanDisk microSDHC from Verizon when they first became available about a year ago. It's easily as fast as my 8GB class 6 ADATA which I bought from Newegg. I did some benches on it when I first got it and was really impressed. I'm sure I posted them here...

Anyway, I never buy memory cards on ebay. It's too easy for people to fake capacity and lie about speeds. Plus a high quality card with a low class rating in my experience is much better/faster than a low quality card with a high class rating.
I agree wholeheartedly, my experience with my Class 2 16GB confirm this.

OUCH, that's still ridiculous, especially considering you can get lucky with an unofficial Class 11 like I did :p.

Check the newegg.com summersale that's going on now: there's a 32gb microSDHC card shipped... $49.99!

That's great you mentioned this, as I noticed the card reader supplied with my "ADATA" card does not have ADATA written on it which makes me slightly suspicious of a counterfeit, despite the card itself looking spot on.

Anyway now that all those have been replied to, the results are in on the "ADATA" 32GB card I purchased.

So as you can see the speeds weren't too much worse on it, and certainly performs above a Class 2 card, according to this benchmark.

Now when real world testing came about it was being written to at about 3-4MB/s, speeds more on par with it's Class #. After I had copied all of my data onto it (10.9GB), I rebooted my computer and when i plugged it back into my machine it asked to be formatted. I would have just shrugged this off but the windows format utility only allowed it to be formatted as an 8MB partition. Which it wouldn't even allow and fail if I tried.

I tried the USB reader, phone, and internal SD reader on my laptop. All of which netted me the same "format E: Drive" and 8MB.

I swiftly informed the seller (knacksnthings) about my card's death and within 5 minutes he had refunded me my $40.03 and told me to keep the card and reader.

Message from the seller if you care to read:
I apologize for the inconvenience. I will issue a full refund for this defective card. You should see the posted refund in the next couple days. the refund will be issued immediately. Some of these cards work, some are stated defective. you can dispose of this, and please if rewarding me with positive feedback, briefly state my excellent customer service. Thanks! and again sorry for the inconvenience

So I'm not mad or anything, as maybe cards sometimes do fail quickly from manufacturers defects. I know ADATA is a great brand and the card does look legit though, so maybe it was just bad luck.

The next card up for review is a Generic 32GB Class 4 for $30 that the seller apparently checks him/herself for speed and capacity assurance.

Figured why not, as this is becoming fun :p, I'll keep you all posted on its results!

Those memorette cards were being sold on XDA Marketplace for a while, glad I decided to wait. Thanks for the reviews!

That's awesome!

Thanks alot for the recommendation, I will include all future results with this test :)

What's even better is it also displays separate read and write speeds!

I look forward to hearing your results, I'm trying to borrow battery testing equipment too so I can start up on those too!

Aww man, :( Guess I know what to expect from mine. I'm gonna give that seller an earful for clearly not testing each one as he claims.

Oh well I guess I should get a new card in my sights for the next round of testing.

sad, because EVERYONE of his reviews are good and flawless except for one bad, and like 2 neutral, and them all being from buying the same 32gb micro sd cards. he probably tests them for recognizing in the computer as 32gbs, which mine did initially when i first got it, but then i ran the test...and we know how that ended up


just did a read only test:

Thanks for the find! I've been browsing ebay for 32gb cards, I've seen one or two other people selling these generic "Memorette" cards. From the looks of it I am definitely going to stay away from that brand.

So here's the Generic 32GB Card, as expected, it is also a dud. I let this user have it (brclc8687) He promised to cease selling the cards and talk to his supplier. With every counterfeit card I shall get more and more outspoken with these sellers.

This card still remains functional after multiple formats and about 2GB is truly usable. When I copy ~32GB into the card it accepts it all but only 2GB of the files are accessible. The remaining are sort of ghost files, each claims to be taking its proper size but none of them will open in the media player (outside the ~2GB of real files). This is good news because it proves that the H2testw application provides an accurate measurement of capacity and Read/Write speeds, I did see writing speeds very similar to those reported from the test.

I will continue to use HD Tune as well even though it doesn't break down the each direction's speed, as it still displays the access time of the card.

I'll let you all know which new card I plan to review! :eek:

Did your SD card happen to ship from overseas? China perhaps? I had this happen with a 16gb card a while back and they shipped it, a Sandisk card. Looked perfect until I put it in the phone and got an SD Damaged error. I formatted it and it turned out to be a counterfeit 2gb card. I eventually got my money back but because of this I will never purchase something like that from eBay aver again. I've had great success with Amazon.

No I only buy from USA sellers, though they're probably the same stuff just some shipped here then redistributed.
I WILL find a good Ebay one and the spread the word, but the amazon one does look more tempting with every passing day and every failing card.

Yeah I've got some pretty cool stuff from Amazon. Never had a problem. Going to get a second Epic from them too actually cause it's $50 cheaper than Spring and Best Buy too. Grabbed some Fishbone Cases for under $4 just the other day!

Glad to know about these fake memory cards

I know this is like 3 years late but... lol I posted a reply to another users post over on another site about my 64gb micro sd cards. the post was over at overclockersclub forums, but being a new user I cannot post the link to it. User IVIYTH0S said to check this posting out on his experience with counterfeit cards. My issue was that the 64gb micro sd cards wouldn't put all my music on them. I'd get some but others would transfer to the card but either the folder couldn't be read and there was an error and you couldn't open it or it would let you into the folder but say it was empty. So I see that the issue happened with the 32gb cards as well. All my 32gb cards are either PNY or Sandisk. Even my 16gb cards are PNY or Sandisk and all of them work perfectly. I see that buying non brand name cards, usually you will run into counterfeit or defective cards. But my biggest issue is the price if you buy a brand name. You guys (back in 2011 I see is when this post and replies were) apparently were paying like $50 or more for 32gb cards. Now in 2014 you can buy brand name 32gb cards for around $25. but the 64 gb cards are $50 or more. It is ridiculous to pay so much when you practically get nothing. You get a small piece of plastic hardware. This is why I went with an off brand or in my case no brand or name cards in which I payed like $6 a piece for 3 of them. I won't do that again after the issue I had with them and what others have said and what I read in this post. I will try the ones that are around $15 a piece. They might just be better. But even so, I think those might be bad too. It amazes me that I found the cards on amazon but they were still defective and counterfeit.

I do like that you are trying to fight counterfeit cards by making yourself heard and letting the people who sell them know. But beware as I have found out that many of the people who sell counterfeit/defective stuff often will give you a refund and provide excellent customer service and sometimes even give you some extra money back as I have gotten with my cards so that you are cool with them and they can continue to do business, I'm one of those that doesn't really care to fight counterfeit stuff because I simply don't have the time to worry about that stuff. I just tend to return the item and get something else and go about my business. But I'm glad there are people like you fighting it when it come across your path. Amazon really should do a better job at weeding out the counterfeiters and people who sell defective products. but I do understand that it is a tough job to enforce so it takes buyers like us to warn others about a seller through comments and flagging the seller.

Anyways thanks for this post. Glad to see I'm not the only one having issues with my micro sd cards.
