Best choice for Raid Arrays only using three dirives.

[Kairo]

Im working on a machine with only three harddrives and I am wanting to use them in a striped array. My question is, is there any way possible I can have striping with redundancy useing only three drives? I know of Raid 01, but Im told there must be four drives.

If you have a controller that supports it, RAID 5 will give you striping with parity which will give you redundancy, BUT you will sacrifice 1 drive's storage space to do so.

e.g - (3) 250GB drives in a RAID 5 array = 500GB storage space. It is fault tolerant and even if one of the drives fails you will not lose your data.

I hope you're not including your OS/Boot drive in that list. It should be separate (best fault tolerance for it would probably be Mirroring).
