If money is no object.. You stripe and mirror. Redundant and very fast. Takes 4 drives.
http://en.wikipedia.org/wiki/RAID
RAID 10 (or 1+0) uses both striping and mirroring.
Redundancy is presumably unimportant since it is already (usually) a direct copy of the contents of the WoW/Data folder on the primary hard drive. Worst case, you re-copy it...TMK you'll have to anyway if there's a patch or whatever (although you can get a "stateful" copy/backup program to minimize the actual copying for slow-write flash SSDs - i.e. it only copies files which have been added or changed).
Note that there are diminishing returns even before you reach any hard caps (bus saturation, the rate the CPU actually needs the data, etc). Say it can load in 1s with one drive...you'd see something like 0.8, 0.75, 0.73, et cetera (to give some arbitrary numbers). One is probably good enough for almost everyone - see the test with launching 13 WoWs off of one. Two with striping is probably nearly as good as any combination could give, but doubtful to be a huge improvement over only one.
"Best" depends upon your requied application. If speed is your peference then you can raid 1 as many dives as you like. One of the beauties of SSDs is that they scale almost 100% within bus limitations. What this means is that you will hit the cap fo onboard contollers with 2-3 SSDs on the read side and you will only see gains with a dedicated contoller.
To be honest I would not really look at using Raid 0 for SSDs as its strength is redundancy whereas SSDs strength is performance. Regularly backups to a regular hard drive would probably be more cost effective.
If you want pure speed, then you can get a high spec areca controller and hook up 8-10 SSDs and get 800MB/s throughput. Alternatively, a product called Ioxtreme is due to be released Q1 next year which looks pretty snazzy.

Just stripe 2 of em (4 if you really want speed, and have the bus for it) and do a nightly backup to a regular hdd. you could do the raid 10 and have speed and redundancy, but i think thats overkill.
Messing up raid0 and raid1 isn't good when trying to help people. 0 = striping, 1 = mirror. Raid0 = speed, raid1 = redundancy/backup.Quote:

For the OP, go with striping (raid0), two or four, like davidoran says. 2 should do you just fine.
