RAID 0 with 15gig and 40gig hard drive?

[imported_nigor]

I am new to raid. I've been researching on Google for tutorials. All tutorials mention that you should have two same hard drives. I found out that if one hard drive is smaller than the other, than raid controller will ignore the extra space on the bigger hard drive. I also found out that the total amount of storage of RAIDO 0 array is equal to the combined space of the hard drives in the array. But there is VERY little information about setting a RAID 0 array with hard drives of different size.

I have a 15gig hard drive and a 40gig hard drive. Will RAID 0 array work with this configuration? Will my total space be 30 gigs or 55gigs? Please shed some light.



Thanks!!

It wouldl be 30 gigs. It really is better though to use to identical drives.

You really wouldn't gain anything noticeable running those drives in raid.

Most raid chip/card manufacturers suggest that you use identical drives to prevent problems. I've always set up my arrays w/ matched pairs (or "quads" in a couple of boxes).
