I'm looking to add a 1TB hard drive to my Time Capsule so I can have wireless access to the files for my iMac, MBA and Dell (XP). I use the TC hard drive for time machine for my two macs, so this hard drive would be exclusively for storing files that I don't want to keep on my computer. I have a new baby and a camcorder which means there are GBs of files added every day. I was wondering what other people are using for a network hard drive and if they are happy with them. Also, I'm assuming a USB HD to the Time Capsule USB port is a better option (faster and more stable) than a true network hard drive (ethernet port). Is this correct? Thanks.
