Is it worth buying SSDs for a RAID?

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.

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.

I'm assuming that this is motherboard RAID? If it is, I would stick with just a single drive. The RAID controller on a motherboard works, but tend to be the lowest quality RAID controllers. For most home users it's not worth it since you really won't see any improvement over what you have right now. I'd save your money and get bigger capacity drives if you want more space.

That doesn't mean SSD RAID's don't have a proper use. Whenever you need high performance hard drive access times, like on a web server or video rendering studios, SSD RAIDs are appropriate.

So unless you are working on high performance business class computers, stick with what you got.

Hope this helps

With the right controller that has trim support, you can, but SSD drives fail fairly regularly so you really want to go with a raid solution that offers redundancy
