Thread: anyone done raid w/ raptor & non-raptor?

Transfer speeds on a raid 0 array will still be better, but since raptors are not known for high...

I decided to scrap this idea, because according to HD tune I'm getting 108MB/sec with my 2 74gb raptors right now. so I dont think it would work so great

I mean e.g. 2 raptors AND 2 80gb normal drives on the very same array... because that is the question currently at hand

why not? you can raid0 different HDDs, you may lose some space, give er a go and let us know.

for hardware raid the drives need to be the same size, or if it does work, it will see the larger drive as the same size as the smaller drive. And the slower drive will bottleneck the faster drive. Raided drives really do need to be matching pairs. edit: I get pretty nice results with a pair of WD 500GB drives in raid 0, and I got them both on sale for ~$45 ea.

It would be like crossfiring two different 4800's like a 4870 512MB and a 4890 1GB. The faster card would slow it's clocks to match the slower card and it would also only be able to utilize half it's RAM. You can only go as fast as the slowest component

you would probably see a bigger benifit getting say 2 or 3 western dig caviar blacks in raid 0. and save alot of money over the raptor+7200 drive. those caviar blacks are pretty nice i have 2 in my server (raid 1, but still speedy)
