Mac RAID 0 Performance Testing

As we mentioned before, because the WD My Book VelociRaptor Duo is not yet fully supported in Windows 7, we aren’t yet able to test the external storage system in RAID 0 on our usual test platforms. However, we were able to test the unit with a Thunderbolt-packing MacBook Pro, and Mac OS X does indeed support RAID 0.

These numbers won’t compare directly to our usual benchmark metrics, but they do show the performance of both VelociRaptor drives running in a striped array.

We’d also be remiss if we didn’t mention how incredibly easy it is to configure the My Book VelociRaptor Duo in whatever supported RAID configuration you want; it takes just a few clicks of WD's intuitive Utilities application.



In the Disk Speed Test, you can see that read and write speeds just about double from our other tests, as we expected--to 373 MBps read and 350.5 MBps write.  Impressive.



Once again we see in the QuickBench test that the WD My Book VelociRaptor Duo managed to hit expectations, and it actually performed better than in the Disk Speed Test, delivering an average of 382.6 MBps read and 362.56 MBps write.  At these speeds, HD video editing should move along swimmingly.
