SATA: IDE mode or RAID mode ?

[mrk]

My mobo is an Abit KW7 and just wnated to know whether I would benefit from using RAID mode for both my SATA channels, when RAID mode is enabled the bios allows me to choose which SCSI controller to boot off (I have 2 sata drives, 1 with windows 1 with docs) so it appears to be able to boot off a single drive when the SATA controller is in SATA mode but currently I use it in IDE mode which uses the ATA133 mode - Am I right in thinking that if I use RAID mode which enables the SATA controller to be seen as a SCSI controller that I'd benefit from the increased performance of SATA150 ?

Here's a phonecam pic of the bios screen for the option if it helps

Thanks guys!

IDE mode uses both SATA channels as IDE channels so you dont need to install any drivers when installing windows and no SATA specific drivers are needed in windows, it is seen as 2 extra IDE channels for use by any SATA drive.

What I wanted to know is if I use it in RAID mode can I still boot off my one windows disk and be able to access my 2nd docs disk as I currently am but of course in RAID mode having the faster speed of SATA ?

Thanks for the info guys, as a final test I ran HSTACH on bth my sata-nxq drives, seems it's all good

Maxtor 200gb (my docs)

Seagate 80GB (windows)

Think I'll leave it in IDE mode!
