September 09, 2013, 12:32 PM — Seagate today unveiled a new Ultra Mobile Hard Disk Drive designed exclusively for mobile devices, saying it offers seven times the capacity of a "traditional" tablet solid state drive (SSD), but with the same reliability, performance and power.
Comparing it to the typical 64GB of embedded flash that comes in tablets, Seagate said its 2.5-in hard drive offers up to 500GB capacity in the thinnest height available today, just 5 millimeters. Most 2.5-in drives come in 7mm or 9mm heights.
Earlier this year, Seagate announced a 2.5-in "solid-state hard drive" (SSHD), that includes both flash and a hard disk drive in a 7mm high form factor.
A Seagate 5mm, single platter drive.
The new single-platter drive is different from the SSHD as it comes with with Seagate's Mobile Enablement Kit, which includes Seagate's Dynamic Data Driver software technology. Seagate claims the software provides SSD-like data protection through the use of enhanced motion sensor and thermal monitoring algorithms to control drive access and avoid usage conditions that might harm it.
Seagate is not claiming that its hard drive alone can achieve SSD-performance, which is often four or five times greater for reads and writes. Instead, Seagate said equipment manufacturers can position the drive along with 8GB of internal flash to act as cache, which will produce SSD-like performance at a much lower cost.
The Mobile HDD and Dynamic Data Driver software use the same power as the flash storage in a 64GB tablet and offer performance equal to that of a 16GB tablet, while costing less than either, the company said.
The drive is "so well insulated that in many cases a dropped device's screen would break before its hard disk drive," the company said in a statement.
"Coupling an ultra-thin, high-capacity HDD with software designed to optimize integration into tablets at a value-add price has allowed us to deliver a truly ground-breaking solution, enabling our partners to reimagine the mobile device," Steve Luczo, CEO of Seagate, said in a statement.
Earlier this year, Seagate released a 2.5-in, 7mm-high SSHD that combines a hard disk with NAND flash to achieve SSD-like performance at lower cost.
Luczo called the Ultra Mobile Hard Disk Drive a "game changer" and said tablet and other mobile device makers should re-think their mobile marketing.
John Rydning, IDC's research vice president for hard disk drives and semiconductors, said today's tablets trade storage capacity for low-power usage and a light and thin form factor.
