the gskill falcon is the same hardware as the ocz vertex, but the gskill support, tools, and firmware updates are either non-existant, shit, or very very late in comparison.
SSD rundown as i have discovered so far: Bigger is better = faster, however more expensive 34nm FTW Intel drives are on paper and in real world tests, the fastest for average gaming/OS use about (be warned they released the TRIM tool, then removed it very fast due to problems) New second gen SSD supports many more tools and options to prevent any problems associated with SSD drives, if you are getting one, make sure its gen 2
Having said all that i just got a second hand OCZ 64 gb SSD, witha firmware update is running sweet. Using that as an OS and standalone (non steam) games drive, and using raptor 150 for all other Steam based games.
Personally I'm running a single 128GB OCZ Vertex. It hasn't missed a beat, and was the speed vs dollars sweet spot when purchasing.
It holds all of my work, the full Adobe Creative Suite, full MS Office Suite and my first person shooters. More than enough room for all primary tasks.
I then have 2.5TB storage on my HTPC, which holds everything else.
