My best guess is yes....it'll work, but they're both going to use the lower speed.

Yes, it will "work." But it will be a poor choice, in my moderately-informed opinion. You lose the TRIM command, the risk of data loss is much greater (do frequent backups that can be restored and booted). EDIT - that last side comment of mine reminded me that I meant to start a backup this morning! Gotta go do that...

If you bought them recently, I suggest that you return them and buy one 320 GB SSD. See this article: http://www.xbitlabs.com/articles/storage/display/kigsto... . If you can't do that, set them up as two separate drives.

But the answer to the original question is yes. You might even get a little better speed than Terryd75 suggested - something slightly over the speed of two SATA II SSDs in RAID0.
