Summary: As the benchmarks show, the WD WD4000FYYZ RE is a solid performer. Partitioning it on our test system was no challenge, though its unusually large capacity might cause problems if you intend to use it with an older NAS. Four terabytes is a huge amount of space; it’s impressive that WD has managed to cram that much data into a drive that runs as cool and quiet as this one does.

Excerpt: In May we tested the first 4TB hard disks, the 7K4000 and 5K4000 from Hitachi. At the time we had hoped that the two other players, Seagate and Western Digital, would also come with their first 4TB disks. That took a lot longer than we expected, but WD does have its first 4TB on the market now, in the shape of the WD RE 4TB for servers. Hardware.Info tested it to find out what it's capable of.
