Does anyone have any experiences with this:

I've got a couple of spare drives around that I could use to make a quick and dirty back up (secondary to the Time Machine hooked up to the home network) of some files. Any long term damage to be concerned about with this type of setup? Wear and tear on the drive pins? I'm guessing heat wouldn't be an issue.
