so your just stickin with xp then
Until they fix the FPS drops, yes... That's the only thing keeping me from using Vista in my main computer.

yes but itsalot easier to buy a 60 buck stiffy and hook it up
thats what i used to do until vista came out with its magical usb stick for drivers
now i never to have to see a stupid stiffy drive ever again

lol why im just stating a fact
dude just go and buy a stiffy drive
its not that bad plug it into your pc and leave it, you'll need it one day for raid

Unless they can sort out my FPS drops I will probably never install Windows Vista on my main machine... Might just wait for the next one altogether

If you're concerned about hard-drive failure, there may be another option. Using Intel's Matrix storage, you can create multiple RAID volumes, each of a different RAID type.
An example using two drives would be to create a RAID 0 volume using 40GB from the one drive and 40GB from the other. Then with the remaining space from both drives, you could create a RAID 1 volume. You'd store all important data on the RAID 1 volume (and possibly an image of the RAID 0 volume, incase of failure) which would still be in tact in the event of one of the drives failing. The downside is that you lose a lot of space because of the mirroing on the RAID 1 volume.
Another option, if you have the cash for more drives, is to use 4 drives. You create a RAID 0 volume using 20 GB from each drive, for example. Then, you create a RAID 5 volume for all of the important data (and possibly the RAID 0 image backup). The benefit of this is that the RAID 5 volume will perform almost as fast as the RAID 0 volume and you would only lose the leftover space of one of the drives.

Geez, 35 posts before someone bothers to distinguish between the different types of RAID...
@carderner, it works like this. With a RAID-0 set (also called a 'stripe'), you have no fault tolerance and your data is spread accross two (or more) discs. Not on a file by file basis, this is lower than filesystem level. More like every second byte/sector on the second disc. Thus if one disc goes bad, you lose the data on both. Advantage: major speed boost, space = disc size x number of discs. RAID-0 is not unstable, it's simply more prone to hardware failure.
RAID-1, contrary to popular belief, are not just slower. Write operations, if you are running software RAID (which is what the majority of onboard RAID solutions really is, otherwise the board would cost R3k more), could get slower if you have enough discs in the set, or for example have two IDE discs on the same cable. Why, because the RAID processing is done by the CPU, so all the data headed for each disc passes from the CPU through the bus/chipset to the disc controllers - so if you have a RAID-1 with three discs, you have three times as much data passing through the bus. If you are doing something write intensive, like copying a big file, this can saturate the bus, slowing down the overall performance. When you're using a hardware RAID controller (such as the ones by Adaptec, 3ware, Areca and LSI) the data passes through the bus only once to the RAID controller, where it gets split up. As for read performance, it's as fast as RAID-0 (weather you use hardware or software RAID) because half the data can be read from one disc and half the data from the other.
Best solution? Buy two more 320GB discs and make a RAID-5 of the three discs (if your board supports it). RAID-5, with three discs, works by keeping parity of two discs worth of data, on one disc worth of space, spread over all three discs. Lose one disc, and the controller can figure out by what's left on the other two discs, what should have been on the third. Advantage: improved performance, your data is safe, and you don't sacrifice half the space.
If all of the above doesn't work, just buy an extra disc of any size, and make it your dat drive. You can move windows' swap file onto it too - should give you a small performance boost too.

yea but whats the point of going into other raid formats
raid 0 is performance all you need to know if your a home user

I didn't see the point in explaining the different RAID types to him, he obviously knows what he wants

He did ask:
and
My point is (which I should have made clearer, but hey, it was way after midnight) is that carderne can have near RAID-0 performance without compromising redundancy.
I guess you can say it's a good idea if you use your computer for play. If you use it for work and can't afford to lose the stuff on it or the downtime of re-installing, spend the extra bucks and get a RAID-5 setup. You won't be sorry.
