This is what I'm doing, although I'm using an Intel series 810 mSATA
ssd. It's only 80 gigs, but it's based on the X-25M controller, and I
trust it a heck of a lot more than some of the other more
"adventurous" SSD controller designs. (Intel tends to be a lot more
conservative with their FTL designs than some of the other SSD
manufacturers.) Currently it's available for around $180.

The trick is to make sure you use a 7mm hard drive. I'm using a
Hitachi Travelstar Z5K500, which is a 5400rpm, 500G drive, which is
available for around $60. The reason why I'm using the older 5400rpm
drive is because I care more about battery lifetime than performance
--- 80G is plenty of room for the stuff that requires low latency
access, which in my case is my system binaries, my home directory, and
my source trees. I keep my A/V media files, build trees with the
object files, and less frequently used bulk data on the 5400pm HDD.
