RAID0 sucks when you throw a drive though, been there dont that with hdd's.
all a matter of your setup. I use raid 0 but backup my data regularly, so if a drive blows out, then that's that. Obviously, without a good backup strategy, there is risk (even if you aren't using raid 0). But yeah, always sucks to lose a drive.
Unlike hard disk drives, SSDs have no moving parts, just electronics, so they should be an order of magnitude more reliable. Of course, FLASH memory does have one MAJOR drawback: it can only be written to so many times (which is why the controller and algorithms used in an SSD are so important, as they spread write operations, minimizing the number of times a single flash cell is written to during the life of the drive).
On the other hand, from what I read and unlike a hard disk, a SSD at the end of its life will not become inaccessible, causing you to lose data: instead, the data in it will just become read-only.
Either way, as so many people have found out the hard way, regular (automated if possible) full backups are a must. Otherwise it's not a question of IF you lose data, but WHEN. And with the price of external 1 TB hard disk drives being so low, there is no excuse not to backup your data (you can even automate backups and make mirror images of your hard disk(s), so you can be up and running again in the minimum amount of time, using software like Acronis True Image).
Here backups are automatically made to two external hard disk drives in alternate fashion, keeping multiple versions up to 3 months old around, and, once a week, critical data is backed up to an offsite location via FTP. All without me having to worry about a thing (except verify from time to time that backups are indeed being performed as they should).
