Can you recommend a 2TB 2.5" hard disk drive for use with a Pi-based network backup server? Preferably one that will reliably run on the USB power provided by at least some model of Raspberry Pi.
Thanks,
Daniele

You might check out Western Digital Labs - I know they have a 1TB drive designed for RPI.
They do: I have their 1TB PiDrive on an RPi3 acting as a backup server, but they don't (currently, at least) have anything bigger than that.

It would be ideal, but I need something quite a bit larger.

Get a bus-powered USB enclosure and put your own drive into it. IME you should be able to go up to about 3TB before you need external power.
Those are 3.5" drives, not USB-powered devices sadly.
Daniele
I may be looking in the wrong places, but nowadays branded external disk drives seem to be cheaper than bare drives!

You could always get a small 4-port USB Hub and hang your drive(s) off of it.
2TB 2.5" drives work well in a USB 3.0 case, though I would consider supplementing the HUb power with a wal-wart supply! Using USB 3.0 cases would allow future use on said bus if needed. :).- Keep the faith, --------------------------------------------------. | | | Ben aka cMech Web: http|ftp|binkp|telnet://cmech.dynip.com | | Email: fido4cmech(at)lusfiber.net | | Home page:

Incorrect.
All USB connected drives I have bought in the last couple of years are powered by USB.
They only *have* a USB socket. How else to they get power?
Note the part of the spec where it says 'USB Powered'...

I think you're looking at the wong thing. Those drives have a 12v power socket and come with a mains adaptor.
I don't think it's even possible to power 3.5" drives via USB, because they require 12v for the motor.
The drives you're referring to are a different product altogether:

Please have a closer look: . It literally shows a picture of the drive, and mentions the mains adaptor.
Yes, but they are not the ones in the link, and not the ones I was referring to...
The link Ray Carter provided was to 3.5" externally powered drives.
The link you provided was to 2.5" USB-powered drives.
The two are from different product ranges.
Actually the 2.5" 2TB drive is a little cheaper than the 3.5" version, but in any case, that's irrelevant. I am the OP, and I want 2.5" drives. They will be fine for my needs.

The 12V jack right next to the USB socket, according to the third picture on that page.
Not quite what you asked for but since January I've been using a Western
for backups and bulk transfer 'though not continuously on-line. No problems and the Pi port drives it for up to the time it takes to play two movies without blinking.
I power the Pi via the GPIO pins - the micro-usb power plug can't deliver enough.
Cheerio,

I didn't refer to that drive either.
