So I just got in four Seagate 7200.10 Perpendicular Recording drives. I've set them up in various configurations on my Mac Pro and benchmarked them.
Specs:
2.66 Ghz (x2) Mac Pro with 2 GB of RAM (512 MB x 4)
Seagate 7200.10 250 GB 16 MB Cache (x4)
Clean install of 10.4.7 booted from a 2nd Gen iPod.
We're using the original Bonnie to do the tests with 2 GB files.
Something else of note; The CPU percentages listed below are out of a maximum 400%, due to having four processors. I'm also basing my read and write speeds off the block transfers and not sequential, as that's a bit more realistic for day to day operations.
We tested 4 different RAID modes, and did a single drive test as a baseline.
