Review on Dell/Seagate Constellation ES ST4000NM0033 4TB 7200RPM 128MB Cache SATA 6.0Gb/s Internal Enterprise Hard Drive – 5 Year Warranty: Reliable Storage Solution for Robust Business Applications by Andrea Ellis

What can be said about such a headline as a hard disk drive? It works the way it's supposed to work. The capacity of 4 TB is enormous and also determines the bit density of a title. The 7200 rpm density combination determines the transfer rate from the disk surface. Because this transfer rate is much slower than the SATA 6 Gb/s transfer rate, the drive can read data into the cache and the computer can flush the cache fast enough that the cache never fills up. This applies to all 4 TB 7200 RPM drives. Most of them are much more expensive than this one. and most of them don't have long warranty like this one. The only real question is how long will it last? Since the answer to this question should be several years old, you probably won't see any reviews with a helpful answer.
