Seagate Releases “World’s Fastest” 6-terabyte Drive

 Seagate now offers a 6-terabyte hard drive the company claims to be “the world's fastest,” with an operating speed of 7,200 rpm. This would make the Seagate Enterprise Capacity 3.5 HDD v4 25 percent faster than any competing drive of this size. Seagate designed the new 3.5-inch drive to meet the needs of corporate users, particularly cloud services providers. “Unstructured data growth is doubling exponentially and will propel the digital universe to reach 16 zettabytes (16 × 1021 bytes) of data by as early as 2017,” according to Seagate vice president of marketing Scott Horn. "This will cause cloud service providers to look for innovative ways to store more within an existing footprint while lowering operational costs.” Seagate increased the density of its drives from 831 to 1,000 bits per square inch, which means they are able to hold more data. This is a 50 percent increase from the previous generation of storage technology, according to Seagate. The new drive will also be available in 5-, 4-, and 2-Tbyte capacities and comes with self-encryption and a humidity sensor. Pricing details were not released. The drive will be available via Seagate’s cloud partners and resellers. (PC Mag)(Computerworld)(Seagate)

Self-Organizing Assembly Shows Promise for Enlarging Hard Drive Capacity

University of Texas at Austin researchers have developed a technique using self-organizing block copolymers that promises to increase hard disk drives’ storage capacity by a factor of five. They are now testing the technology with HGST, a Western Digital company formerly called Hitachi Global Storage Technologies. Storage capacity, which relies on magnetic dots closely placed together on a metal surface, is at a current maximum of approximately a terabit of data per square inch. The University of Texas researchers determined that physically isolating the magnetic dots by placing no magnetic material between them increases the storage density. They are using block copolymers as a coating over the disk’s surface for patterning a drive quickly with tiny dots. The material forms the desired patterns using directed self-assembly, a process which uses molecules’ ability to re-assemble into ordered structures. The academic and HGST researchers are evaluating the technologies to determine whether they can be scaled appropriately for conventional manufacturing. The work was published in the journal Science.
