Great GENUINE card,
Verified Purchase(What is this?)
This review is from: SanDisk Mobile Ultra microSDHC 32 GB UHS-I Class 10 Memory Card 30 MB/s + SD Adapter + Memory Zone App (SDSDQU-032G-U46A) (Accessory)
Was looking to increase the memory on my HTC Desire HD phone, from the 16gb it had.
Steered clear of eBay for buying SDHC cards, due to the amount of fake cards out there (appear to be certain capacity, but "hacked" to show larger size on smaller cards).
Was dissapointed first time I bought a simmilar (no-brand) card from Amazon - turned up in non-original packaging, print (logo etc) on card itself rubbed off.
This time round, went for a good branded one (sanDisk ONLY do memory, so better than even Samsung - sanDIsk actually make the memory rather than simply badging).
Arrived in proper "bubble pack", fully branded, even had a login for some SanDisk media software (which I wont use - but shows it's genuine).
Ran h2testw to test capacity and speed of card to check genuine - this tool basically takes the stated size of the card (as set in the card - this can easily be hacked to appear as WHATEVER SIZE THEY WANT). Then, it writes test files to the card till it's full - which will match the shown size of the card if it's genuine.
Mine reported as follows - which confirms it's definately 32gb, and the R / W speeds are in the upper end of the spec for a Class 10 card like this - pretty impressive numbers!
Test finished without errors.
You can now delete the test files *.h2w or verify them again.
Writing speed: 7.72 MByte/s
Reading speed: 18.9 MByte/s
Now, on to the phone...
Connected phone to PC via usb and copied entire contents of SD card to folder on Desktop.
I (unmounted) and removed the original 16gb card from my phone (HTC Desire HD), taking the bottom of the case off to access.
Left the back off to allow easy access to put the new card in.
Put the new card in... and it WOULDNT READ IT!
Couldnt mount it etc - phone just kept saying it was safe to remove the card.
Had heard that the DEsire HD cant handle a class 10 - gave up for a bit and thought about it, researched the issue.
After a break finally twigged - the DHD has "connectors" in the bottom part of the case that you take off to put the card in. Without this back on (and connectors in place) it doesnt power the SD card or the SIM (obviously some benefitial purpose - dont know what off hand).
ANyway, put the case back on - and Voila! Worked first time... :)
Copied everything back to SD card from PC, partitioned the card to add EXT4 to install apps into (rather than the fixed memory phone) using CyanogenMod 7.2.
Happy to report all is good - having this extra memory onboard allows you to max out some of the memory optimisations CM7 - did all of those and the phone now works fine - noticably faster.
NB - for anyone looking for a Micro SDHC card bigger than 32gb - you wont get one... 32GB is the max for the specs on Micro SDHC, though I believe there is another version of Micro SD (X... something or other) that can handle bigger.
All in - good price, good card, good specs - dumb owner for a few minutes (! ;)) would definately recommend. BUT be careful of fake cards, always remember to select AMAZON.CO.UK as the "Fulfilled by" when purchasing here, to avoid getting some fake PoS from some 3rd party here on Amazon like i did the first time.
Remember to put the blo*dy case back on if it doesnt seem to work!
The Micro SD -> SD card adaptor thingy is VERY difficult to get the card out of again. I had to use a pair of pliers the first time. In the end, bent the back edge of the adaptor card down so I could get it out next time.
Highly recommend this unit - hope this review has helped others answer the same concerns I had when looking for one of these...

The card you bought was great

As Y.Bain says 7MB/s isn't a good write speed for this; either the reviewers hardware is at fault or the card faulty or fake.

bought the 64gb UHS-1 class 10 sandisk card. and tried checking it with 'h2testw'. it shows like 2hrs 50mts to complete the test. is it normal? does it normally take this much time?
are there other good apps to test the read/write speed of the card?

Haa why are you giving this 5 stars when you have a 7mbs write speed ? That is not class 10. It's minimum should be 10mbs write speed!

Just thought I would let you know that Samsung produce memory and have done for years in fact they are one of the biggest producers of NAND storage. That said SanDisk do make very good cards.
