For a single USB  drive, probably, but what about multiple USB drives, perhaps USB tuners, an HD-PVR or two and other 
things on that USB bus at the same time?

Then there's the kids plugging in iPods, mobile phones and other things just to charge them. That USB bus is starting to 
look pretty crowded and problem-prone.

I'm sure it's improved, but I recall my early experiences with USB 2.0 devices and Linux, I had a lot of mysterious 
freezes and outright crashes, some of which were due to poor USB implementation by the device makers, but the Linux USB 
drivers made their contribution as well.

I forgot about the spin-down, good point, but for long-term off-site storage I think plastic disks may be a better answer, 
far less infrastructure required.

Of course I also have DLT tape, but the media cost there is just unreasonable, and I don't expect it to improve.
