Western Digital VelociRaptor 1TB Review - 10K RPM Hits a Larger Capacity
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.
Steady progression of bursts over the drive generations.
Yet another steady climb of performance.
All VR models benefit from very fast seeks due to reduced rotational latency at 10,000 RPM.
