I have a WD My Cloud box. You can get them with various sizes. Although this is a bit more expensive than the cheap USB drives today, consider the benefits.
1. It is a raid 0 array, meaning it automatically makes a copy of anything you put on it. No more worrying about when the last time you duplicated, what photos got edited, added, what ones do you want to protect from overwrite, etc. There are two drives in the bay and their firmware takes care of the duplication. If you want a 4TB solution, the box comes with qty 2 - 4TB drives. You save a file and in the background it's copied to the other drive in real time
2. It is network attached storage (NAS), meaning you don't have to tether it to your computer's USB and no worries about multiple computers.
3. It has a cloud feature whereby you can get your files from anywhere without a $$ subscription, (including your phone or tablet, say you want to show a picture you don't have on your mobile device) it's your drive and your stuff. It has as much security as any other internet based source. It goes through mycloud.com to setup the internet path.
4. It has power settings that allow you to put it to sleep on the overnight or when you're not going to be using it.
5. It's performance is the same as if you had a file server in your own home or office. This was my biggest concern, but I will say it is as fast as the USB drive route. I use Wifi into my 1gb switch. If you are wired into your network, its even faster.
6. You can pick the size.

Then one of the drives quit, and although I had the backup that was only 3-4 weeks out of date, it made me realize how vulnerable this method is. I love the simplicity of how this personal cloud works.
