I say, get this:
Sonnet Technologies Tempo 6Gb/s SATA PCIe 2.0
It's $100, put your SSD on it, and clone your startup disk to it, and enjoy the new speed and sparkle it gives your mac in the form of boot times, launch times, and such. 500mb/s read/write instead of 100mb/s.
It's very easy and quickly done.
Later you can move on.
