I bought this as a home server for 150 euro online. It's made by Netgear who are a well known reliable brand.
It's ideal for a home network and also as a back up. If consists of a sleek glossy black box that has a USB port on front and at the rear it has a power button and an Ethernet cable slot.
The power lead is long and I am able to plug this in under neath the desk and shove it out off the way in the corner. There is a light at the front that goes blue or red depending on whether it is copying files. It looks really good and it's small too at only about 15cm wide and high.
It can contain two hard drives inside. One hard drive copies the data and transfers it to the second hard drive in case of hard drive failure. This is a fantastic concept but the stora only includes one hard drive of 1TB and the second hard drive will have to be bought and installed separately.
I have been using it for over a year now to store family videos, movies, pictures, and work files. It's nice knowing we have a back up if the computer fails us. You can connect to it by any device in the house by setting up a network. Including your tv!
It has a really functional and easy to use interface. You must install the Stor software first. Itis fast to transfer and retrieve files from. I can wirelessly connect to it with my laptop too which is another added bonus.
Perfect reliable network storage device that i would recommend for serious storage use.
