I just did a benchmark of my drives running on RAID 0 - notice, the fastest single drive you can get - a 15K RPM, SCSI320 - drive does not even compare to the dual Seagates running on RAID 0. It beats me seek wise by 1 ms, but transfer is not even close. I also added drives similar to mine running on RAID 0 and I am still a tad faster with myself at 90 MB/sec than the Maxtors at 84 MB/sec. 84 MB/sec is still decent though.
