This Deskstar 7K2000 hard drive delivers a colossal 2TB of storage capacity and 7200 RPM performance in a standard 3.5-inch form factor. 32mb cache as standard too.
Novatech offers free delivery for if you are active on their forum, but if not - there is still 3% quidco.
I think this is a pretty good deal. Even if you aren't eligible for free delivery, I'd still reckon Novatech is better choice than Ebayer - who offers this drive at similar price; cos the free delivery of Ebayers lately is a bit slow.
