There is nothing to indicate that RAID0 under linux software RAID would be any slower or faster than RAID0 on one of the HPT or Promise "RAID" controllers. If you want higher performance on that, you need real hardware. Of course these hardware sites reviewed RAID favorably because it gave some performance hains in Windows over the regular stuff, but realize that these are basically WinRAID controllers. Obviously if many windows users have the setup, and feel the need to access their WinRAID partition (yeah singular--you get _one_ RAID partition with these controllers) and use dual-boot, a project would be in order to assist them, but notice it is not by commercial distributors. Even the linux-ide project has no personnel involved. Andre Hedrick wrote quite an interesting letter about this junk on kernel traffic, more than a year ago, as you can discover from the link Tom posted. For right now, the Promixe RAID controllers are supported for one drive per channel, as regular controllers, and the HPTs seem to work somewhat better as regular controllers. There is a supported hardware IDE RAID documented at www.linux-ide.org and it does work very well indeed. It is a tad on the expensive side, but it could work wonders in limited space (one device runs two 2.5" notebook size drives as a RAID0 or RAID1 totally transparent to the system in a single 3.5" bay--great for a high-reliability thin box...
