I would suggest getting 2 64gb's and setting up a raid 0+1.
Use the SSD's for striping, and a mechanical for mirror.
I suggest the raid because of an idiosyncracie inherent to all SSD's, they do not process game maps very well when they are stand alone. Loading the OS and any file or program, they smoke. They just have a problem with the large map files. It is still faster than a standard drive but would kill the velociraptor once in RAID.
To answer your first question, I went with the Patriot Torx. Same price as Corsair, same controller, and Patriot is right here in Fremont. Anything happens, they are right down the road.
One thing to keep in mind for anybody wanting SSD's, go to the manufacturer's website for the one you get, and download the latest firmware. You WILL need it when you recieve your drive. Flashing is easy, you plug in the drive, make sure the jumper is on, go to an existing OS, and run the update. Do this before loading anything because this will wipe the new SSD.
