HGST HAS AGAIN GONE WHERE no hard disk company has gone before with the world's first 10TB hard drive with enterprise credentials for Active Archive.
The Ultrastar Archive HA10 SMR HDD continues the company's line of helium filled drives, and is the second to use Shingled Magnetic Recording (SMR) to increase density and therefore capacity to 10TB.
The technique involves overlapping tracks 'shingling' to pack more in. There is limited capacity for rewrites, but the drives are ideal for archiving and the growing big data storage market.
The Helioseal technique, which involves filling the drives with helium and sealing them, allows the drive head to sit closer to the disk thereby improving the accuracy of the write and read while boosting durability at the same time.
This technique drives down the total cost of ownership (TCO) of the drives, and in a large scale roll out the company's strategy is continuing to keep a gap between the TCO of HDD and SDD which has narrowed in recent months thanks to products such as SanDisk's InfiniFlash array.
HGST estimates that 20 to 35 percent of data being stored is Active Archive or Deep Archive, with a projection of up to 50 percent in the next five years.
"HGST's helium-filled drives boast industry-leading storage density, low power consumption and proven reliability with 2.5M hours MTBF," said Brendan Collins, vice president of product marketing at HGST.
"By layering SMR on top of helium, we are enabling massively scalable, TCO-driven storage solutions with the performance and durability necessary for the long-term retention of archived data.
"Making SMR design investments today minimises incremental efforts for future SMR solutions, and gives our customers a time-to-market advantage for all current and future high capacity HDDs in the market."
Rollout will commence with customers that already have the software development infrastructure in place. The company will work alongside the open source community to implement Linux-based software and is offering an open source SDK to aid developers.
Dave Tang, VP of engineering at HGST, explained the other advantages of the Ultrastar Active approach in a recent interview with The INQUIRER.
"When it comes to capacity, mechanical disks still have the advantage in cost per gigabyte. I mean you could compare it to tape, but that doesn't have the accessibility," he said.
"With Active Archive we now have what's called Erasure Coding. Whereas RAID restoration can take weeks, Erasure Coding looks at pools of thousands of devices and, rather than try to grab the image of the failing device, it will reconstitute the protection that drive provides, creating a self-healing environment."
Erasure Coding is one of the reasons why HGST has more than a little respect in the industry. µ
