Since I work in an office environment where the Windows OS is in limited privileges, I make heavy use of Portable Apps and am no stranger to buying USB keys. Even running in USB 2.0 (at work), this drive is leaps and bounds over any drive I have purchased recently. While the discontinued Throttle and discontinued 8GB GT drives were lightning fast, I have had a spate of very bad 64GB purchases recently which, while patriotic, were horrendous (including huge CPU overhead and extremely slow small file copy).
Anyway, this drive absolutely flies. Copying lots of very small files (word documents, Eudora data) through very large files (huge zip files), the drive is great. For those intending to run Portable Apps within a Truecrypt container, even in USB 2.0, it is leaps and bounds ahead of any other drive I have owned.
I am extremely glad I purchased this drive.
