Is it possible to RAID0 two different sized drives? I didn't think it was, but thought I'd ask.

If not, could I partition the larger drive to the same size as the smaller one, RAID0 the two partitions (one on larger disk and the other disk), then use the remaining as a standalone drive?

Only asking because a second 128GB SSD is a bit steep, but I could use some more performance and space.

You can RAID0 two different sized drives, but it rarely works very well xD
Not sure bout the partitioning part, sorry.

Yes, you can RAID different sized drives, no need to make partitions - RAID is at a deeper level than that. You will always be limited by the smaller drive (ie a RAID 0 of a 200GB drive and a 500GB drive would give you a maximum of a 400GB logical disk on the array) You are also limited by the performance characteristics of the slower drive, which is why it generally isn't considered such a great idea.

yes that's right. I don't think I would bother RAIDing the SSD. I'm not sure how the controllers would deal with different sized disks.
