If you do a RAID 0 setup you will get a performance boost. It's a good idea.

I beleive I have hardware ATA RAID controller, becuase when I'm booting up with gentoo
doataraid kernel option
the setup says it is detected and when I do modprobe ataraid, no errors appear. When I
do modprobe pdcriad or hptraid.
modules can't be loaded with a bunch of errors, so I assume that I have ataraid. Now,
if I do Kernel configuration,
what options have to be selected? How can I collect more information about my ata raid
controller from Windows machine?
( I do not have Linux installed yet, struggling) 1)Do I need to select HPT336/337C
chipset support? 2)Do I need to sellect
IDE Raid support? ( I think I do ).3) Highpoint? No, right, since mu modprobe failes.
Or do I have to select them all?
Do I have to create /mnt/gentoo/dev directory before mount it?
Do installing the system on ATA RAid have some advantages? ( I have install Slackware
even without knowing that
Raid exists).
Thanks,
Walther.
Code listing .1: Loading RAID modules
# modprobe ataraid
For Promise Raid Controllers:
# modprobe pdcraid
For Highpoint Raid Controllers:
# modprobe hptraid
Some ATA RAID Controllers require you to reboot after partitioning; formatting will
otherwise fail.
Before chrooting, mount the devicetree into the new environment:
Code listing .2: Mounting /dev into /mnt/gentoo/dev
# mount -o bind /dev /mnt/gentoo/dev
During kernel configuration, select the required RAID options:
Code listing .3: RAID in the Linux Kernel Configuration
For Highpoint RAID controllers:
ATA/IDE/MFM/RLL support ---
[*] HPT36X/37X chipset support
[*] Support for IDE Raid controllers
[*] Highpoint 370 software RAID
For Promise RAID controllers:

[*] PROMISE PDC202{46|62|65|67} support
and/or
[*] PROMISE PDC202{68|69|70|71|75|76|77} support
