Hard drive and memory

I ordered an additional hard drive for my datastore.
I ordered the Western Digital Caviar Black 640GB. Its said to be the best sub-terabyte drive in the market. I got it cheap for £51 inc. vat and shipping from ebuyer.com

From http://compreviews.about.com/od/storage/tp/SATAHardDrives.htm
"If you don't need a huge hard drive but are looking for a solid performing drive that is a bit more affordable, then the Western Digital Caviar Black 640GB is the choice. The drive actually uses the same platters used by the terabyte Caviar Black version, but instead uses two rather than three platters. The result, a drive with the same level of performance but uses a bit less energy and is more affordable to those that don't necessarily need to store as much data."

This is a sata II, 3GB/s, 7.2k rpm, 8.5ms ave. seek time, 32MB cache drive

I have also received my memory form www.overclockers.co.uk. I ordered Corsair XMS2 4GB (2x2GB) DDR2 PC2-6400C5 TwinX Dual Channel (TWIN2X4096-6400C5)

Note that these have got heat sincs for perfomance and reliability. I got them for £42 including vat and shipping.
