Seagate ships first 8-TB hard drives

Seagate is the first customer to see cloud providers and companies looking to set up a private cloud. General availability is announced by the manufacturer for the fourth quarter of 2014.

First pilot customers already get the first 8 TB disk from Seagate. In general, the largest HDD of the manufacturer will be available in the fourth quarter of 2014. At this time, Seagate would then also announce prices and other technical details.

For companies that want to set up their own cloud environments, as well as cloud providers Seagate currently offers hard drives with storage capacities from 500 GB to 6 TB. Whether the new announcements work on the same technological basis, as the largest plate in this category so far or whether technical improvements were required for the additional capacity, Seagate has not yet announced.

So far, it is only known that the 8-TB models come in 3.5-inch format and are also equipped with SATA interfaces with 6 GBit / s. According to the manufacturer, they should therefore be able to be integrated into existing infrastructures without additional effort.

For the current 6TB top-of-the-range model, Seagate promises a desktop workload 10x workload rating and an MTBF of 1.4 million hours. In addition, with Seagate Instant Secure Erase with self-encryption, it provides users with the assurance that data once stored on the disk will not fall into the wrong hands when it is disposed of. For the 8-TByte variant one may expect these characteristics as minimum equipment likewise.

The Western Digital subsidiary HGST had begun in November last year to deliver for the now targeted by Seagate customer groups 6-TB disks. Its special feature is the helium filling. The benefits of using helium-filled hard drives have been known to the industry for a long time. However, the vendors tinkered long on the product and process design to seal helium in the context of mass production cost in the HDD housing.

HGST, according to Anagben, needed six years to present a prototype – and another year to organize mass production. As a helium-hard drive, the manufacturer claims cost savings through more fuel-efficient operation: The power loss per drive is 23 percent lower than conventional models, and the TByte-to-Watt ratio is 49 percent better. This is achieved by the fact that the density of helium is only one-seventh of the density of air. As a result, the flow effects to which the rotating plate stacks are subjected are reduced, and the motor that moves the individual platters requires less power.
