I have tried integrated IDE raid but found it to be at best buggy, mostly
noticeable with large files. Which although nobody should be mailing 200 meg
+ files it isn't really a good sign you woulbn't want to buy a car that was
only safe to drive at under 70 mph and blew up at 71 mph.
I then got an off board card (AMI I think) which supported full raid 5
rather than just 0,1 or 0 & 1 ( sometimes called raid10 by some
manufacturers ) This worked flawlessly, however it does require 4 identical
drives for raid 5.
The ABIT VP6 (I think) is a nice cheapy board and can support 8 ide devices
which gives you raid 0,1 and 10, plus 4 ata 33 drive support, but is a dual
socket 370 board for about �100 quid you could try that in a test enviroment
and if not happy add an off board raid card, other than that a good dual
board for the money. Not bad for dual CPU and raid.
For the system I used IBM deskstars (30 GB), these are slightly more than
other makes but I really rate them, normally I go with good old plodders
maxtor mainly for their advanced replacement policy which is great where
large drives are involved. And to cap it all off aluminium removable drive
bays which allowed hotswapping with software help and worked with all speeds
upto ATA 100 and 10,000 rpm (these can be tricky to track down).
The last item was a 5th drive for ghosting the finished build onto for quick
recovery should two drives or the raid card choose to fail to swap the
machine over to single drive operation in about 5 minutes due to the hot
swap bays.
This machine ran and still does flawlessly all for sub �1000.
