My first deal post on here. I have been looking for a USB 3.0 hard drive recently and this Western Digital 1TB drive seems to be quite a few £££ cheaper than I have seen it elsewhere at the moment for a quality brand.
I just bought this from Amazon for £63.34 (it says reduced from £89.99) with free super saver delivery and bought a PCIe Adapter for £13 (through Amazon from MyMemory).
£89.99 from Pixmania.
£97.18 from Scan.
