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.

HDTach burst hang in there with the rest of the field, though burst testing of an SSD yields mostly inaccurate results.

Octane did well in sequential transfers with HDTach, but remember this particular test hits drives with a string of sequential (QD=1) IO, a notorious weakness of SandForce controllers.

Here’s a hint of what’s to come. OCZ was heavily pushing Octane’s lower latency as a bonus. Here we see it on-par with the Intel 320 Series. It’s no surprise that it’s also on-par with the original Indilinx Barefoot (in the Vertex 1).
