WinBench 99 - Transfer Rate Test
We ran WinBench 99's Disk Transfer Rate Test to get a better measure of just how well the transfer rates are over the course of the entire disk. The Disk Transfer Rate test reads from the media in a linear fashion from the beginning (first track) to the end (last track). The numbers below represent the ceiling and floor of the transfer rates throughout the test.
The transfer rates reported for the single 160GB 7200.9 stepped down steadily from just under 75MB/sec to about 38MB/sec. The transfer rates reported for the 2x160GB RAID-0 array was a lot more inconsistent as it jumped all over the place. HDTach will give us a cleaner view of the performance of each setup.

If you have a large, PATA backup drive, then the chance of failure issue really isn't that big a deal, especially with the longer warranties (Raptors are enterprise class products for WD, aren't they?).The interesting question to me is, does performance increase with 10,000 RPMs, SATA bandwidth AND increased platter density.
I believe the Raptors aren't 3.0 GB/s SATA but they still should have plenty of room to run, and if I remember correctly, the 150 GB Raptors gained their extra space by a higher density platter than the 74 GB version.
Now that's a setup that might be worth $600. It all depends if it lives up to the potential. AnandTech, let's get a SATA RAID-0 Shoot Out going!!

Oh, and in general, great articles lately :)DS Delaroca - Friday, January 27, 2006 - link
i think he means the new raptors WD1500ADFD 150GB on a raid setup.
