Looking for an external USB drive at 1TB; THEN WAIT!
Read up on this unit first. For around £30 more you can get this unit that sits on your network and works in the same way, plus remote access, automatic backups of your computer(s) data in the house. Allows 3 remote user accounts.
Looks like Netgear are pushing this unit at a low price now, as I have just found it at other suppliers for a similar price. A collegue recently bought the 500MB unit for over £150!
Pay the £15 per year (optional) upgrades to unlimited remote accounts, and will allow automatic backups of computers data not on your own network (kids at university as a good example)
Even without the £15 per year, remote users can drop files on the STORA for safe keeping.
Add a second hard drive (very easy to do) and the unit will copy your data onto the second drive as a backup incase first one fails.
Absolute steal at this price.
