HD Tach will test the sequential read, random access and interface burst speeds of your attached storage device (hard drive, flash drive, removable drive, etc). All drive technologies such as SCSI, IDE/ATA, 1394, USB, SATA and RAID are supported. Test results from HD Tach can be used to confirm manufacturer specs, analyze your system for proper performance, and compare your performance with others. HD Tach is very easy to use, quick, and presents data in easy to read graphs, including the ability to compare two storage devices on screen at the same time for easy analysis.
Colossus bursted faster than the single Indilinx equipped units.
Given SATA commands must pass through two layers of nested SII5923 controllers, I suspected the Colossus might be slower than 0.1 ms on our Random Access Time test. Luckily this is not the case. We will see more on this with our new IOMeter Transaction Time testing (seen later in this article).
