If you're talking about a SSD that is supposed to replace your HDD, then those drives "act" just like the HDD in your computer now. They use the same interface so they can just be popped in as a replacement.
My only concern is price. Maybe I've missed it, but the prices on these things are through the roof. If you've got a macbook, you'd got a lot more bang for your buck by just buying a spare battery (or five). I can't imagine the speed increase will be worth the money for everyday tasks.
Of course, it's your baby so do what you think is best.
best of luck.
