This isn't exactly on topic but I use an SSD for my boot/OS/programs drive and a RAID1 array for my precious data/Steam/Games/Videos/Music/etc.
It works pretty well, although I'm using the Intel fake-raid.
The SSD was the best upgrade I've ever bought though, screw the RAID array, get an external HDD to backup to and grab yourself a _good_ SSD for your boot drive.
Hell if you can afford it go for one of these:
