Three RAID-0 Generations Benchmarked

[SonataSys]

I have recently benchmarked three generations of disks configured in a RAID-0 array using a dual Xeon system running with an integrated SATA-I RAID controller.

I was expecting better performance numbers from the newest VelociRaptor array, but I suspect my older SATA-I controller is a bottleneck.

I would be interested in how this compares with other benchmarking efforts.


WD VelociRaptor 300GB (10,000 RPM) RAID-0 600GB Array

Analysis:

• 24% improved average and max. transfer rates compared to the WD Raptor array
• 32% improved average and 29% improved max. transfer rate compared to the Hitachi Deskstar array
• Slight improvements in burst rate and CPU usage

WD Raptor 74GB (10,000 RPM) RAID-0 148GB Array

Analysis:

• 11% improved average and 7% improved max. transfer rate compared to the Hitachi Deskstar array
• Not much difference in burst rate or CPU usage

Hitachi Deskstar 400GB (7,200 RPM) RAID-0 800GB Array
