Super Talent USB 3.0 DataGuardian 32GB Flash Drive Review

Storage/Other by stefan @ 2012-01-13

The new DataGuardian USB 3.0 Flash Drive from Super Talent gives us the possibility to protect the data stored on it by locking its entire filesystem with a password; the user interface that pops up when the drive is inserted is user friendly and we can re-enter the password two more times if we got it wrong the first time.

The DataGuardian application interface which pops up right after the drive is plugged in is really simple to use; initially, we are asked for a password to associate to the flash drive:




A confirmation of the newly inserted password is needed, for safety:




Next time the DataGuardian interface pops up, we can use it to type our current password for initiating the Lock or Unlock procedure of the rest of the filesystem; in case of a password error, we have two more tries left:




To determine the flash drive read speeds, in both Normal and Turbo modes, the HD Tune 4.60 utility was used:



HD Tune File Benchmark 64MB


HD Tune File Benchmark 512MB

To measure the real life performance, I have used the Total Commander application to copy to the flash drive and from the flash drive the same file and recorded the transfer speeds, when they have stabilized.
