Seagate Technology on Tuesday unveiled the world’s first hard disk drives with 8TB capacity. The HDDs are designed for scale-out data infrastructures that require maximum capacities at minimal footprints.

Seagate did not reveal a lot of technical details about its 8TB hard disk drives, but it said that the HDDs come in 3.5” form-factor, use the Serial ATA-6Gb/s interface and feature enterprise-class reliability as well as multi-drive RV tolerance for consistent enterprise-class performance in high density environments. Super-sized capacity of 8TB allows to store maximum amount of data per rack, which therefore improves storage densities and maximizes efficiencies of data-centers.

The hard drive maker did not unveil how many platters do the 8TB HDDs use and what type of magnetic recording technology they utilize. Earlier this year it was believed that 8TB hard disk drives feature platters based on shingled magnetic recording (SMR) technology, but Seagate neither confirmed nor denied the information. The SMR platters are projected to offer lower performance compared to perpendicular magnetic recording (PMR) technology, but Seagate also did not reveal any performance figures.

“As our world becomes more mobile, the number of devices we use to create and consume data is driving an explosive growth in unstructured data. This places increased pressure on cloud builders to look for innovative ways to build cost-effective, high capacity storage for both private and cloud-based data centers,” said Scott Horn, Seagate vice president of marketing. “Seagate is poised to address this challenge by offering the world’s first 8TB HDD, a ground-breaking new solution for meeting the increased capacities needed to support the demand for high capacity storage in a world bursting with digital creation, consumption and long-term storage.”

Seagate said that it is shipping the 8TB drives to select customers now with wide scale availability next quarter.

KitGuru Says: It will be extremely interesting to learn more about technologies behind Seagate’s 8TB HDD as well as its performance. If Seagate managed to bring performance of SMR-based drives closer to that of PMR-powered drives, it could use the new recording technology for consumer hard drives as well, which means an increase of their capacities.

Seagate Technology on Thursday said that it had shipped the first samples of hard disk drives (HDDs) with 8TB capacity to its customers. The company did not reveal any peculiarities regarding the product or the name of its clients.

“We have also delivered 8TB customer development units to major customers and cloud service providers and the initial customer feedback has been very positive,” said Steve Luczo, chairman and chief executive officer of Seagate, during a conference call with financial analysts and investors.

Seagate did not disclose any details regarding the drive, but there are not a lot of ways to build an HDD of such huge capacity nowadays:

  • Increase the amount of platters per drive. Seagate could follow its rival HGST with sealed hard disk drives. It is possible to fill a drive with a gas that is less dense than the air (e.g., Helium, like in the case of HGST’s Ultrastar He6) and then squeeze seven (or even eight Seagate it manages to develop all-new magnetic recording heads) current-generation enterprise-class 3.5” platters of enhanced capacity (1TB – 1.1TB). Such approach greatly works for server-class drives, but it is clearly too expensive for consumer-oriented HDDs.
  • Increase areal density of platters. Seagate could install six enterprise-class platters featuring shingled magnetic recording (SMR) technology into a non-sealed drive. SMR helps to increase areal density of HDD platters by 25 per cent compared to current-gen platters featuring perpendicular magnetic recording (PMR) technology. While SMR is not yet widely used even for consumer hard drives, it is possible that the technology progresses so successfully that Seagate already has samples of enterprise-class SMR platters. Hard drives with five or six platters are usually designed for servers.
  • Significantly increase areal density of platters. Seagate could ship prototypes of drives based on platters that feature HAMR [heat-assisted magnetic recording] technology. Back in 2012 TDK demonstrated 2TB HAMR platters for 3.5” HDDs, so Seagate could use them to test-drive HAMR hard drives with its PC and server customers.

It is unknown which method Seagate chose for its 8TB hard disk drive.

Keeping in mind that Seagate talks about 8TB “customer development units”, the actual commercial drives of such capacity are probably several quarters, if not years, away from mass production and adoption.

KitGuru Says: It will be interesting to see what exactly Seagate shipped to its customers. All three options are interesting, but if the company is finally on-track to commercially produce HAMR-based HDDs in the foreseeable future, then this is a sensation.
