This product is currently in stock and there is a massive 40 Gigabytes on this Hard Drive Disk.
It is SATA which is better than most IDE drives on the market and it is very speedy at 5400RPM (2.5 Inch so it won't take up too much room in your PC case)
£112.32 is a fair price including VAT considering it is 5400RPM
There are some good reviews on this website so it seems trustworthy
