To potential buyers,
I have been using this “product” for over two months now on a Windows 7 64-bit system.
IMO, the people here at SanDisk support obviously do not care about supporting this product and it’s users.
The Cache fills up and renders my system unstable. The Cache also resets.
I am using the latest release of the 1.3.2 ExpressCache software. The software has not been corrected yet.
Amazingly, other people who have HP systems do not have a problem with HP’s 16 GB solution, which uses the ExpressCache software, among other vendors. If you don’t believe me, just google reviews of this product, especially comments from Amazon and Newegg.
Caveat Emptor! Wish I could say different.
