A while back, I bought a Seagate “FreeAgent GoFlex Home” network-attached storage (NAS) device - essentially a hard drive with a network port that does not need to be connected to a computer. I had two goals in mind: my digital music collection had outgrown the old PC I use for that purpose, and backups of my various home PCs were a haphazard mess. I could have spent several hundred dollars on a new computer to serve this purpose, but I thought I'd try something new and try my luck with a ~$150 NAS device.
