I plan to use a 1TB 2.5-inch USB3 disk drive, powered via the USB cable from
the Pi, as a first try. If that's successful and the family needs more space
for shared files, I plan to move to a USB3 multi-disk box with its own power
supply. I'll probably configure the box as a JBOD so I can use software RAID.
USB2 disks are, of course, slow by modern standards, but they do work -- as
long as you don't overload the bandwidth. Is that what you mean by
"miserable". USB3, on the other hand, is plenty fast enough for a NAS
driving a 1Gbit LAN -- depending on the speed of the underlying disk drives, of
course.
I've done this kind of configuration before. If you have specific questions,
I'll be happy to try to answer them...
Enjoy!
Rick
