	Just one thing, use the -t flag to newfs (along with whatever
others you use) when you initialise the filesystems to enable TRIM support,
other than that it's just a (fast) drive.

	Provided the existing filesystems will fit on the SSD a migrate in
place is quite easy. I have done this quite recently based on the excellent
write up here - don't
treat it as a step-by-step adapt it to your setup (not hard).
