Hi, I currently have an internal 120GB and I'm considering my options for further storage. I want a large external drive to store all my music/pictures and videos on. I was looking at the seagate expansion dekstop (3TB) drive, or possibly the USB 3.0 mybook studio as it's designed for mac (supposedly) but I don't want to use any rubbish software that comes pre-installed on the drive. Can you wipe any pre-installed crap that comes on a drive? I feel confident in putting a second drive in the mini itself, but I don't think I have much purpose for it. I won't be planning on moving the mini anywere and I can either hide a large external drive or buy one that looks good, so putting a 1TB HDD inside the mini might be a bit of a waste of money. I have a 500GB external 2.5 drive I will be using to keep backups of pictures/music in case thhe large external should ever fail. The seagate expansion or mybook both look decent but have their fair share of bad reviews, anyone here use either of these?
