Questions about RAID 0

stridervm · Jan 30, 2016

I have these old 500GB hard drives laying around so I just started toying with the idea of using software RAID to increase performance for games.

At the left side is the two drives individual Crystalmark result. At the right side is the result(s) after striping the drives. I have noticed that the first drive is very slow compared to the second drive although (Perhaps the earlier one has issues.) which affects the resulting striped drive performance. The only increase is the sequential read.

I am expecting to at least a marginal increase to the resulting drive. It is still reasonable to RAID 0 these drives or would the striping just bring the overall performance down due to the slower drive?

Maybe one drive is 7200 RPM and the other is 5400 RPM - giving the speed difference.

Raid 0 - especially on older drives is a bad idea. Yes it can increase performance, but it also increases the chance for data loss. If one drive dies, you lose the data on both drives.

The slower drive would slow down the performance of the raid so the overall effect would be slower than the faster drive by itself. You'd be better off just using the faster drive by itself.

Using RAID 0 won't really improve your gaming other than maybe loading maps a little faster. I'd say the difference in the drives is that one is SATA II and the other SATA III.

I do not mind the risk of data loss on the striped drives. That's a risk I'm willing to take.

But still if the overall performance of the drive would be slower (Except for the read speed.) then I guess I would just keep the drives seperate. Thank you for replying.

Thank you for the reply.
