SanDisk Ultra Fit 128GB Review (Page 6 of 8)

Page 6 - Benchmark: HD Tach

About HD Tach

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 possible.

While HD Tach's sequential read performance is more of a 'drag race' approach to evaluating storage performance, it still provides valuable insight into how good a drive is compared to the next. From that above, I was able to pull a 42.7MB/s sequential read speed from the SanDisk Ultra Fit 128GB in a flat line. Of course, this is far from being the fastest we have seen from a USB 3.0 flash device, but again, I must point out how small this drive is. Just for comparison, Kingston's DataTraveler microDuo 32GB delivered 28.5MB/s in the same test, but the SanDisk Ultra Fit has a lot more capacity. For what it is worth, this is probably not going to be indicative of real life performance by any means, but at the end of the day, these numbers show us the relative performance between devices.
