raid two different drives?

[rumbl3]

I know werid question or i know i'll get the reply of BUY A NEW HARD DRIVE lol.

But i'm jsut curious if i can raid say my 100 gig and 120 gig and see a gain? Is that possible? never done a raid before.

Or would i be better off just leaving one as a storage and not even bother to try this?

I believe there both 7,200 rpm 2mb cache drives.

Well if the two drives are of a similar generation so that one drive is not waiting for the other, which it sounds like they may be, then you could put them in RAID 0 or RAID 1 and see a speed increase. As to what happens to that other 20GB's I'm not sure. RAID1 would ignore that 20GB's so total usable space is 100GB's with redundancy and a faster read time. RAID 0 may also drop that 20GB's of space since it alternates the blocks from drive to drive as data comes into the array.

It really does come down to if the two drives are the same speed. Even if both are 7200RPM and 2MB's of cache, there are other factors that could make one faster than the other which would slow down the array vs using just the faster drive. Try some benchmarking first on each drive.

You can RAID the two, but you will lose the 20gb on the bigger drive.

I wouldn't recommend raiding them though. I did it awhile back and it stuttered horribly.
