Yes, it's safe.  I've had the RAM cache turned on for a year now on my
5Mb SE/30 and have had no problems.  If you select shutdown from the special
menu in the finder before turning off the computer, the integrity of your
disk is assured, and your Mac will start faster the next time you turn it on.
The only place you're at all likely to have problems is if the power to your
Mac cuts off unexpectedly, in which case it's kind of a crap shoot anyways
as regards to your data.
