It is also silent in rotation as compared to access my WD Green 1TB EADS that it is noisier access. I intended to choose the WD Black 1TB initially, but I find that the higher price is no reason to be because it is noisy, consumes more and more low flow (150MB max), the best black access time and longer warranty is not adequate to overcome disadvantages.
The SV35 has exactly the same performance as 7200.14 as access speed, the differences are:
-Price higher (10 euros)
-espérance longer life
-end against 2 years 3 years
-no parking untimely heads that is detrimental to the reliability of a disk
