Is it worth me sending back the WD6401AALS and exchanging it for the much better reviewed WD6400AAKS? Is there much of a difference between the two drives? Is mine the better or worse of the two?
Hehe, you have done alright there - you got the more expensive model with more cache - double the cache actually. As long as it works and the warranty still counts - stick with what you got - its faster, unless you need that £5.
