The Sandisks are great. They are "enterprise" though. The backup (compression) software is very useful, as is the robust nature of the device (there's no cap to lose and the USB "dongle" is protected when not in use) and the fact that it is extremely easy to tell when it's in use (very noticeable light).
They are undoubtedly not as fast as the Corsair, or as sexy. But they do the job. And it's amazing, but since I got mine quite a lot of other people I work with (including many from other organisations) have bought the same drive.
