The problem with hard drives is that a failure of any drive, in any way, would cause data loss - how big of a loss is a matter of coincidence.
With SSDs, what we have seen so far has not been a failure of NAND, but rather of the controllers (we've seen entire SSDs become unusable, in different forms). So far I have had 2 X25-Es out of 4 fail in the same manner - one UNREDABLE sector (which is quite odd for NAND!), and have seen a few other X25-M failures similar to it

The data should be retrievable, however, the cost would probably be higher than the drive is worth.

RAID0 itself is not an issue with SSDs, the controllers themselves... I am not too confident yet (I have 3 different SSD types at the moment, and I ran most high-end SSDs for testing at least - X25-E/M and C300 are used ATM).
