AnandTech re-reviews the Hitachi DeskStar 7K1000, this time with a pair set up in RAID 0.  They find very little difference between the real application performance of this drive in single or RAID 0, nor can it keep up with the Raptors.  However, if you are looking for nice looking benchmark scores, you definitely want the RAID.
“With all that said, the purpose of today’s second look is to provide some initial RAID results with this drive and convey our experiences with the 7K1000 after having additional test time with it. We had a deluge of reader requests asking for test results in RAID 0 based upon the overall performance of the drive being near, equal, or better than the Western Digital Raptors. We are not fans of RAID on the consumer desktop; especially motherboard based solutions, but nevertheless thought it might be an interesting exercise to see how two of the top performing drives in the consumer SATA market compare against each other.

Sure, RAID 0 will certainly provide some very impressive synthetic benchmark scores, PCMark05 being a prime example, but in actual applications we see it having more of a placebo effect than providing any real performance gains. Our technical briefing and commentary on RAID 0 can be located here. Let’s see how the Hitachi Deskstar 7K1000 and Western Digital WD1500 drives perform in RAID 0 across a variety of benchmarks. ”
