WD1500AD Raptor X-Tends Performance Lead

Showdown Between 7,200 RPM RAID 0 And The Raptor-X

We used two Seagate NL35 drives running at 7,200 RPM to build a RAID 0 array, which can be considered an alternative to Western Digital’s Raptor-X.

We took the new 10,000 RPM WD1500AD Raptor and compared it to a 7,200 RPM RAID 0 array, since this would be the alternative if performance and high capacity are important to you. We took two NL35 drives by Seagate since these were available ; technically they are not very different from the Barracuda 7200.8, and thus one of the faster 7,200 RPM models available. We realize that two 400 GB drives would be an investment that easily exceeds the costs of one WD1500 Raptor. However, using two 300 GB drives is doable for roughly the same price, and this should result in a storage subsystem performance that outruns the WD1500 Raptor... or maybe not ?
