Is it worth buying SSDs for a RAID?

Solution 1:

RAID 0 should get you faster reads and writes, but you do you really need that? Note that if you lose one drive of a RAID 0 pair, you just lost the volume, where with with two drives operating independently, you've still got the data on the good drive.

Also, note that without special driver support, you'll be giving up TRIM support on the array.

I think RAID implies AHCI, on Intel boards at least.

Solution 2:

I found this article to be a better summation which essentially matches my experience with SSD: excellent performance, high failure rate, all failures are catastrophic.

For my money, I'm avoiding them from now on until they're a little more reliable. I don't have that kind of disposable income. I would certainly not consider using them in RAID-0 unless a) I was not planning on storing any data on the computer and b) I was not planning on using the system for any critical functions.
