Every time I've tried to use a single SSD on a laptop I haven't had much success and I've seen lockups for a few seconds.

I've use some Intel SSDs on a caching raid controller and I've never seen locks.
I have NEVER had good success with OCZ whether it was SSD or memory chips, I refuse to buy them.
I always use Crucial main memory so hopefully they make a good SSD, too early to tell right now, So far no problems.
