Produce consistent, solid is fast. I ordered it to extend the memory of my netbook (emachine N355). The card itself works very well, the concern has come to my side, a poorly installed driver, said that records my videos / images / etc download windows were gone along detect my card. After several tweaks and tests of all kinds to recover these files, which of course did not work, backup, and reinstall W7 drivers. It works !! I pass under linux with a connected external dd, then back under W7, and there was no different because the drive letter of the card changed ... So re-instal W7 and the card and now under the letter (Z :) and for more worries, playing movies and music are done correctly.
In summary a very good card with a cost / interesting storage and me reliable air time. 5/5
PS: if you also wish to extend your pc with storage, choose a drive letter that does not conflict with any external hard drive, USB key
