Kingston DataTraveler Ultimate 64GB USB 3.0 Flash Drive Review

HD Tach v3.0.4.0

HD Tach is a low level hardware benchmark for random access
read/write storage devices such as hard drives, removable drives
(ZIP/JAZZ), flash devices, and RAID arrays. HD Tach uses custom device
drivers and other low level Windows interfaces to bypass as many layers
of software as possible and get as close to the physical performance of
the device as possible.
