Wow, okay lots of replies and I'll address them here. First, a lot of people are talking about using two drives. On Windows this model does not work. Moving programs from C: to D: will often screw up registry settings and other crap like that. On OSX and Linux, thanks to a single root filesystem and symlinks, this model might work better. Furthermore, I have to manage moving files back and forth. This is a problem algorithms should take care of and no OS does this yet. Secondly, a lot of people are saying the Momentus benchmarks are terrible. This seems obvious. Any standard benchmark does not take advantage of a large read cache. You have to use some sector of data over and over again in order for the drive's algorithms to put it into the SSD cache.
