New to RAID

[WWII]

I've built many PCs, but never a RAID configuration. Am I correct in
assuming that two 40GB HDs in a RAID 0 configuration will have a total
capacity of 80GB (less some overhead)? Also what performance can I expect
from a S-ATA RAID 0 configuration compared to two separate IDE drives?

Thanks.

There are several 'flavors' of RAID. Some provide speed,
some provide redundancy (backup) and some a combination.
If you just plug RAID into Google, you'll have a ton of
good information. Like many other things in life, RAID
can be very useful, but it's still no 'free-lunch'.

Correct

2 40gb Drives in a RAid-0 Configuration gives 80GB
usable, and also high performance as the system can read
from disks in parallel to achive high data transfer
rates. Downside is that loss of either disk will result
in data loss, so you are twice as likely to suffer data
loss with Raid-0. Other option with 2 drives is RAid-1
(mirror), which only gives 40GB usable, but is tolerant
to single disk failure.

agreed...
Unless you are trying to squeeze the last ounce of perf
out of your machine for 'game' purposes, I see little
advantage, and some disadvantages, to RAID.
