I have a 600 GB WD VelociRaptor installed as an extra data drive in my machine. I decided to test its speed with a benchmarking program. The results seem disappointing: the sequential write speed is 124.7 MB/sec, and sequential read speed is 132.3 MB/sec.
By way of comparison, I have an external hard drive attached over USB 3, and the results there are 143.0 MB/sec, and 169.5 MB/sec. It is a descent drive, but only 7,200 rpm.
Am I missing something in expecting the VelociRaptor to outperform a 7,200 rpm external hdd in sequential write / read speeds?
The SMART attributes for the VelociRaptor all seem normal, no errors are detected. It is attached to a newer SATA interface. I also have write caching enabled on it...
Thanks for any thoughts / advice.
