more mac help needed

Joe, whether or not you use time machine, get an external drive that functions in RAID 1 mode. You will have half the capacity, because each file is mirrored, provided pretty strong safety (you would have to have both drives fail at the same time to lose your data).

If it's a good one (recent LaCie) it will be hot swappable, meaning you can replace a drive if it fails, and all the data will be copied from the good drive to the new blank one - all the while you can keep using the device.

As someone above mentioned, your drive WILL FAIL. And you can't always count on Time Machine - my MacBook drive failed a few weeks ago, and while the home directories were recoverable, the Applications folder was lost. Not a major catastrophe, but big pain in the ass.

In my opinion, you are best to keep all your precious stuff on the external RAID, and not depend on Time Machine.
