Conclusion The HGST's Ultrastar 7K4000 is an enterprise-class HDD that is now being offered in capacities up to 4TB (as in our 4TB test model) with a 3.5" form factor. The drive also provides the enterprise with some high-end features. The drive spins at 7,200RPM, interfaces over SATA 6Gb/s, and is offered in Advanced Format using a 4096-byte sector size. The drive's new 4TB maximum capacity provides users a 33% capacity boost over previous 3TB models by using five 800GB platters. As we evaluated the HGST Ultrastar 7K4000 in our Enterprise Synthetic Workload test, the Ultrastar was competitive with the Seagate Constellation ES.2 3TB and 2TB and 4TB Western Digital RE4 drives. The Ultrastar performed very well in particular during our 128K sequential test that shows a best case scenario for hard drives. The drive also tested well in the 8K 70% Read/30% Write evaluation. On the other hand, the drive consistently had higher latency across the Web and File Server profiles and was also had lower performance in our random 4K tests. On top of those features, the Ultrastar 7K4000 provides enterprise organizations with features that will be important to them. It offers high endurance and includes a 2 million hour MTBF, which is quite a bit higher than other drives on the market such as the 1.2 million hours offerred by the WD RE 4TB. The 7K4000 is also rated to meet some significant power marks with overall power usage up to 59% lower during low RPM idle mode. These features along with the expanded capacity and maintained footprint make the drive attractive.
