The 16GB DataTraveler Mini 3.0 has a tiny form factor, manages passable read speeds and is priced aggressively. With sequential read/write speeds of 76/8.9 MB/s the DataTraveler Mini has an acceptable read speed but a very poor write speed. At 8.9 MB/s a 4.5GB DVD would take a very painful ten minutes to transfer. Small file 4K speeds are better and clocked in at 6.9/0.25 MB/s which is average for a 16GB USB 3.0 flash drive. The best thing the DataTraveler Mini has going for it is its price point which is very reasonable. Overall the DataTraveler Mini 3.0 is let down by its unforgivably poor write speed which results in an effective speed rating of just 41.1 MB/s, barely above USB 2.0 levels. [Mar '14 USBFlashPro]
