But remember that SSD's have a limited life! All those switching operations will take their toll.

If it is just booting that you want very fast take a look at Hybrid drives. They cache frequently used files into a small amount of memory on the drive. The other files are kept on the magnetic platters like normal.

The lifespan is significantly greater.

I try to make sure that my VM images are NOT running off my SSD on my laptop to ensure I get maximum life.
