My setup isn't as fancy as most people, it's simply a 500GB Western Digital 2.5" external drive connected via USB.
Why a 2.5" drive and why USB you might ask:
- I used to use an external, dual 3.5" WD drive connected via FW400. Yes it was fast, but it was about 10 times louder than my Mac mini, because of the dual 3.5" drives enclosed together. The fans are almost as loud, if not louder, than an old PowerMac G4 tower. I said enough is enough!
- being low-power, it draws power directly from one of the USB port of the Mac mini (intel Core 2 Duo), so there's no power cable and no wall wart for that drive
- being low-power, it practically doesn't make any noise
- it doesn't take much room on the desk
My plan is to never use 3.5" drives ever again. Too big, too power-hungry, too noisy. By the time I need another 500GB of storage that same drive will probably be on sale for a quarter of the price I paid for mine.
