Putting 2 SSD drives in Raid 0 is a pain because you have to monitor the speeds and every once in a while you have to wipe the drives with a program called HDD Erase.
You really need to do more research on SSD drives. It's important to know that some people don't know what they're talking about either. Some fool who works at Microsoft was going on about how MLC drives are better than SLC drives.... When in fact SLC is better and faster. One thing about them (SSD drives) is the performance degrades over time, it's because the cells in a SSD become cluttered. Decent SSD drives support a cleaning system called TRIM. Sadly, when 2 SSD drives are put into RAID 0 the TRIM support will not work.
The good news is Intel is working on a version of it's IRST program that will support TRIM when two SSD drives are place in RAID 0. It's just not available yet.
RAID 0 will double your 4k read speed and at times you will see the difference. Raid 0 doesn't effect access times and it does little to help out small clusters.
I have ran raid 0 in the past and the only time I had an issue is when one of the drives in the setup failed. When you run RAID you just have to worry about one of the drives failing. If you buy 4 hard drives, you increasing the chances of failure because of the numbers involved. You're not increasing the chances of the individual drive failing, it's just that you have more drives to worry about. If one of the drives fail then you will lose all the data. So it's important to back up the system on an external drive.
