I was planning on going with the Velociraptor 300gb as a boot drive for my mac pro. Then I was thinking maybe 2 400GB Samsung Spinpoint F1's in RAID-0 might be quicker. NOT TO MENTION HALF THE PRICE and 100 gb more storage. I have seen benchmarks of the two at barefeats Although the F1's in the comparison are 640gb the performance should be on par with the 400gb correct?Looks like the spinpoint F1 striped outperformed the velociraptor single in every category besides random 4k read. Thoughts? Reliability of raid as boot drive? Half price?
