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.
USB 2.0 Header:
Benchmark Results: The OCZ Enyo 128GB USB Storage Drive averaged 35MB/s on a USB 2.0 header and ~194MB/s on USB 3.0! The burst speed on the USB 3.0 header was 178.7MB/s and 38.9MB/s with the USB 2.0 header. The random access time of 0.4ms on USB 2.0 was sweet, but the USB 3.0 header had a much improved random access time of just 0.1ms!
CrystalDiskMark is a small HDD benchmark utility for your hard drive
that enables you to rapidly measure sequential and random read/write
100MB Files Test on USB 2.0 Header:
100MB Files Test on USB 3.0 Header:
Benchmark Results: Another popular testing application that is free is CrystalDiskMark v3.0g. We ran CDM with a file size of 100MB on both the USB 2.0
& 3.0 headers to see how performance was on the OCZ Enyo 128GB drive. As you can see the sequential read performance went from ~44MB/s to ~265MB/s and the sequential write performance also improved from ~39MB/s to 180MB/s. As you can you see the OCZ Enyo is quick on a USB 2.0 drive, but if you use it on a system with a USB 3.0 you can have huge performance improvements!
