I am sure this has been answered before but I can't seem to find a solid answer.
I am thinking about using a RAID 0 setup for my OS on my next build and instead of buying two nice drives, what if I went with three or even four cheaper drives. I know adding drives is supposed to increase performance, but is there diminishing returns when doing this?
Also can I rely on the motherboards RAID controller or would I need to get an external card?
This build will be used for a bit of gaming and as a mid level development server
The more drives you put in RAID 0, the greater your risk of failure - any drive failure & you lose data on the entire array. For gaming, maybe that's not an issue - for development, is your data in a different location?
I'd stick with 2 nicer drives, or an SSD, plus frequent backup.
From what I've read, you might consider WD's RE drives. I've heard that you shouldn't have any problems with a drive dropping out of the RAID do to the drive timing out. They cast a bit more, but if you data is safe...... that's the whole point.
I just installed 2 Samsung Spinpoint F3 500 gig HDs in raid 0 config in my second rig in my signature. I created a 250 gig first partition for the OS and games and another partition for data. It's fast! Got both delivered for $89!
