I've updated my rig - a little bit.
I bought a new Intel Cherryville 520 SSD (180 GB)
and made it my main drive, and relegated my X25-M as a slave drive back on the regular SATA II channel. Best buy had them on sale for $159.99 + tax. A bargain, if you click the link and see hat it is currently going for (not counting eBay auctions).
Using a great little utility called Profile Relocator
I've reinstalled Win 7 from scratch and moved the entire User tree for my profile over to the older SSD. Now, I have gobs of space for games, all my regular apps, and my profile is also on a fast SSD.
Win-win situation. I still have the dual 1 TB Barracuda mech drives for storage.
