I'm thinking in getting a RPi+USB HDD to make a server in my office, it would be working 24/7 and the primary usage would be to storage backups which would be automatically uploaded from different VPSs.
As far as I known, USB2.0 supports a maximum current of 500mA, and RPi can handle up to 2A, so there shouldn't be any problem, but I think it would be convenient to supply the HDD with a powered USB Hub to avoid RPi to handle that current, which a long term, it may damage RPi (?), or am I being overprotective?
So... Which would be the best way to increase the RPi storage? (talking in terabytes)
