Netgear 1100
Aquired from Infrant Technologies, a NAS unit that boasts it's power consumption, and size for a network. We have a 4TB model, and about 1.25TB is used for the OS on the RAID5 array + raid overhead. Runs linux and is quite slow on the network responsiveness, but it does have lots if not everything you're looking for.
I tried briefly once to put BSD on it -- I didn't succeed -- main reason is I don't know what CPU is in it, what driver for ethernet, etc.. gave up pretty fast.
We bought this as an attempt to get a working solution at work for the files people need, and when i started doing the math when we were backing up a FULL unit, it would take 7 days to back up. We abandoned it for that reason.
