Do you REALLY want them IN YOUR COMPUTER?
External disk drives are dirt cheap. In today's Fry's Electronics newspaper ad, they have a 2 TB [that's 2,000 GB!] for $89.
I have 2 external drives. 1 that I work from, and 1 strictly for backup. I learned my lesson when I had an internal drive fail, with 2 years of pics I didn't have anywhere else, and I have a quote from DriveSavers of $700 to get it recovered.
Isn't an external drive slower - working through the USB cable? I have a second internal drive for data, and I use externals for backup.
