I ended up buying two OCZ Vertex 4 128GB drives and put them in RAID 0 via
the motherboard's "fake" RAID. The Intel P67 RAID controller on my
motherboard seems to be surprisingly good and well supported. The Windows 7
installer detected it without even having to install the drivers (but I did
anyway). The drives work very well and I'm very pleased with the
performance. I don't think I'll need to get a dedicated RAID card soon.

I always do incremental partition backups to a separate hard drive every
two days, so even if something fails, it doesn't take long to restore to
another drive or partition and keep working until a replacement drive is
installed.

@Peter, SATA 3 makes a huge difference, especially on my system. I can do
greater than 1GB/s reads and writes (benchmarks) to my RAID 0 array at the
moment.

@David, I store everything on these SSDs and make backups every two days to
other drives. There's no point using SSDs if you're not actually going to
use them.
