4.0 out of 5 stars How to check its a genuine card, 21 Jan. 2013
Verified Purchase(What is this?)
This review is from: Kingston Technology Micro SDHC 32GB Memory Card (Personal Computers)
There are far too many fakes about and its essential you test your card on receipt, some fakes will pass some of the test programmes, so test with ChkFlsh, Crystal Disk Mark & especially H2testW. H2testW tests the full capacity of the card, so will catch any using aliasing to fake larger than real capacity. A card with full capacity but high error rate/slow write speed indicates a 'ghost run' fake.

I`ve added images to the product gallery to assist in visually identifying genuine & fake cards.

Good results:
A 32GB card should have a formatted capacity of around 30GB, format in FAT/FAT32 only (NTFS shortens life of flash media & wont improve performance)
A class 4 card must have a write speed of 4MB/s minimum (large files) the first result in Crystal Disk Mark should indicate that.
Read speeds should be over 12MB/s.

Very good review, thanks for all the useful info, I have tested 2 cards, a 16gb and a 32gb Kingston microSD and they both proved to be genuine via kingston´s website and good read/write speed with h2testw. Thanks!

Hi, could you help me out by telling me if this micro SD card you've tested is really not compatible for use with an ereader. It says under its descriptions that the card is not compatible with standard microSD-enabled device/readers. Does this literally mean books can not be stored on the card, and that it cannot be used on an ereader?
I apologize in advance if this seems to be a silly question. I'm just desperate to find a micro SD card I can safely use with my ereader.

Surely if you buy it from Amazon, it will be genuine without the need to check using various programs?

Unfortunately not the case, Amazon is not able to control its sellers absolutely & some do sell fakes, as I can assert to personally.

Charles says:
There are different variants of micro SD cards, currently Micro SD, Micro SDHC and Micro SDXC and cards are not backwards compatible, that means these Micro SDHC cards will not work on older Micro SD devices, which is what the description you mention means, i.e. buy Micro SDHC compatible or better readers.

You're talking about Amazon marketplace, i.e. third party sellers.

Amazon themselves don't sell fakes.

Not entirely, if you read through some reviews some that have selected Amazon as seller still seem to have received fakes, that may be as sometimes buying from Amazon actually means an approved seller. Also if you look into things far enough you'll discover fakes have worked their way into the official chain at times, this being more likely for 'ghost run' fakes as they're done in the same factory as originals and with the same packaging, only identifiable by duplicated numbers across batches and testing as the sub-standard (rejected) material used has poor performance and short life.

My advise, always test, then your sure at the start, finding out months down the line is often too late.

Thanks for all this information, I have a dud card but wish I'd been more clued-up sooner. I shan't get caught out again thanks to this newly acquired knowledge. Cheers, Michael.

Very good review. A seller that sells fake is LittleSwan2006 and refuses to take his fake product back. So everyone beware of LittleSwan2006. Read through the review of this product and you'll see that LittleSwan2006 has been reported to sell fake - I wonder why Amazon isn't doing anything about it.

Hi there,

Thanks for the great info you have provided, much appreciated.
Just wanted to know would this Micro SD be good with the GoPro Hero 3 (which records 4k, 1080p HD resolution )
