RAID 0 On Mixed Drives?

[demoneye]

Hi,

I'm running a single OCZ Vertex Series 30GB 2.5" SATA-II Solid State Hard Drive (OCZSSD2-1VTX30G) on a Abit IP35 Pro (Socket 775) PCI-Express DDR2 Motherboard. Can I add another SSD (OCZ Vertex Series 60GB 2.5" SATA-II Solid State Hard Drive (OCZSSD2-1VTX60G)) or have they got to be a matched drive to run in RAID 0?

Would I better off with two additional 30Gb drives or a single 60Gb?

Generally it's possible to run RAID0 across unmatched drives but the array will be twice the size of the smallest disk. The remaining space is usually unavailable but the Intel RAID controllers can do some fancy stuff with Matrix RAID which can allow you access to this space as a second volume.

Personally I'd stick with matched drives if at all possible.

Yes, you can raid them, but I don't think it'll work as you expect. Best you could hope for is a 60gb raid 0 volume and a 30gb jbod volume, where writing to the 30gb volume adversely affects the speed of the raid and vice versa.

You would be wiser to get a second identical drive, ideally flash both to the latest firmware, and raid zero those for a single 60gb volume.

edit: too slow...

And I assume I'd get better performance from 3 x 30Gb anyway? Yes?
