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.
Burst rates were consistent across both cards. Write speeds for a given RAID configuration were also comparable, but the Areca was able to take better advantage of the increased read throughput of our M series drives, reaching nearly 900 MB/sec. HighPoint has some room for improvement here, especially when used in a stripe+mirror (0+1, or 10) configuration.
