I've been rather demoralized by the development race in HDDs, but after the laugh last years WD4001FAEX gave me, I've been rather pleased to watch the review of the new black edition drive. Even though still far from what I'd want to see, as this is the first performance upgrade from WD after 5 years old 2TB Black edition.
I'm currently out of storage and will want new large drives soon. But I don't know if these drives will fit in my system. SSD is for the OS drive. A RAID-0 array of 2 1TB Velociraptors is for the gaming drive and the rest are pretty much for pure storage. Maybe these drives would be an overkill for storage and I might opt for other 4TB drives. It will depend on the price difference.
