Im after two of the above hard drives, but the place where i shop keeps running out of stock and chances of them having some in stock by thursday or friday coming is looking very bleak, As ill be building my system by friday. so does anyone know of any HD's that are just as quick for around the same price of upto £75? Capacity of the HD's is not really necassary, but i don't want expensive Raptors or the like, i am considering an SSD, but that will be later in the build. PS; ive read that the 500GB Western Digi, Caviar black is nowhere near as quick as the 640Gb, is this true? Thanks all, dan.
