4 IDE drives will do 300MB/s today, an Ultra320 channel is less.

Well, to tell you the truth... RAID0 over 12 Hitachi 160GB/8MB 7K250 drives
(SATA), on 3Ware 9500S-12 SATA RAID controller, and I could get 350MB/s
read
and 210MB/s write speed... How the heck could you get 300MB/s on 4 ATA
drives?!!!!!

3Ware 9500S-12, 128MB cache, PCI-X 66MHz
12x Hitachi 7K250, 160GB/8MB, 64kb stripe size

PCI-X/66 is 480MB/s, the 3ware's CPU is not capable of filling it.

On previous generation chipsets, the ICH5 was measured around 200MB/s with 4
drives a couple years ago. The ICH6-MCH link is as fast as PCI-X/133, and is
available on $100 mainboards.

Hardware RAID cards often have a STR bottleneck, which is not important for
most server applications.

The machine was a video-capture workstation... Tested with BlackMagic

software for video-capture speed testing... Capture card was BlackMagic
Design DectLink Extreme IIRC...
