And recover/reconstruct the data (that is split in half) across two SSDs? I just haven't noticed enough real-world-usage improvement using RAID-0 (perhaps related question) and would like to use the 2nd SSD for something else. I do have a pre-RAID disk image from a couple of days ago.

In short, is there a straight-forward way to revert a RAID-0 set? Thank you.

If you break a RAID-0, all data on it is lost. To "recover" data from a RAID-0 you need to back it up to some other disk first, then break up the RAID, create new volumes on the single disks, and restor ethe data to the new volume(s).

Can one restore RAID-0 from a Time Machine backup? – courteous Sep 11 '12 at 5:52
Sure, as long as the backup doesn't reside on that same RAID-0. – Ansgar Wiechers Sep 11 '12 at 18:31
