Mirroring the HDTach theoretical read tests, the DataTraveler mini gives a good showing in our file copy read tests for small and big files. Performance comes in just a smidgen faster than that of the DataTraveler ReadyFlash drive.

Write performance is where things go downhill for the mini. For both the small and big file copy write tests, performance is on the low end, marginally slower than the OCZ Minikart. For the casual user, this performance still translates into usable speeds, but if you are going to be writing to the drive frequently, there are much faster options available. Note: For the file copy tests, files are copied to and from the USB flash drive and the time taken is measured. This time is divided by the total file size transferred to get the average transfer rate. For the Small Files test, a compilation of 165MB worth of small (1kB to 5MB) is used. For the Big File test, a single 478MB file is used.
