ST6000NM0024

WD60EFRX

We took a look at the Hitachi 6TB Ultrastar He6 drive a few weeks back and we liked it very much. Today we look at what competitors have to offer. Here we have the Western Digital RED 6TB WD60EFRX and Seagate Enterprise Capacity 6TB ST6000NM0024. 

Western Digital having only just released the new WD RED range a few days ago, i guess feeling it was nessasary to release a 6TB drive to compete with Seagate and Hitachi, which have had their 6TB HDD's out for a few months now.

The Seagate Enterprise Capacity 6TB V.4 is billed as the “world’s fastest” nearline HDD currently on the market, with claims of performance 25% over competitive offerings. With an operating speed of 7200RPM, the Seagate V.4 also comes in 5TB, 4TB and 2TB flavors. Each type can be purchased with either 12Gb/s SAS or 6Gb/s SATA connectivity, allowing it to be easily integrated into current systems. Seagate also supports optional SED and FIPS encryption.

WD Red hard drives are architected specifically for the distinct environment of NAS as well as the increasing demand for affordable, reliable, and compatible storage that strive to reduce customer total cost of ownership. The 5TB and 6TB models allow for greater storage capacity and increased performance with NASware 3.0, which is an enhanced version of WD’s original NASware technology that is designed to improve reliability and system performance, reduce customer downtime, and to simplify the integration process. In addition, the WD Red line of HDDs feature 3D Active Balance Plus, an enhanced balance control technology that substantially improves overall drive performance and reliability.

We have taken a look at three different 6 TB drives, but it is hard to recommend any particular one as the clear cut choice unless the particular application is known. The interesting aspect here is that none of the three drives have overlapping use-cases. For home consumers who are interested in stashing their media collection / smartphone-captured photos and videos and expect only four or five clients to simultaneously access the NAS, the lower power consumption as well as the price of the WD Red 6 TB is hard to ignore. For users looking for absolute performance and those who need multiple iSCSI LUNs for virtual machines and other such applications would find the Seagate Enterprise Capacity v4 6 TB a good choice. The HGST Ultrastar He6 is based on upcoming technological advancements, and hence, carries a premium. However, the TCO aspect turns out to be in its favour, particularly when multiple drives running 24x7 are needed. It offers the best balance of power consumption, price and performance.
