Western Digital WD10EARS
1TB Hard Drive
OEM Caviar Green.
6.2p per gb
this is selling for 3p more than the 32mb cache version of the same drive at ebuyer.
As hard drive capacities increase, the power required to run those drives increases as well. WD Caviar Green drives make it possible for energy-conscious customers to build systems with higher capacities and the right balance of system performance, ensured reliability, and energy conservation.
this drive is currently £66.49 at amazon but I wouldn't be surprised to see amazon updating thier price to this soon.
(10:59 just checked ebuyer updated the price to £62.98 was £63.00 early in the morning :) )
