Western Digital Unveils New Mid-range Enterprise HDDs
Published2018.01.25 10:19Western Digital has unveiled the 4TB, 6TB, and 8TB air-based mid-range HDDs, the Ultrastar 7K6 and Ultrastar 7K8.
Western Digital, a leader in the high-capacity enterprise HDD market based on its helium-filled drive technology 'HelioSeal,' is expanding its portfolio for enterprise customers with the unveiling of this new mid-range HDD. Unlike hyperscale and cloud environments where 10TB, 12TB, and 14TB high-capacity drives are in the spotlight, traditional data centers still often rely on RAID-based block-and-file systems that arrange multiple standard-capacity drives.
Western Digital’s new mid-range HDDs under the HGST brand help enterprise data centers with small data sets utilize various big data applications, such as analytics and distributed file systems.
For example, distributed file systems such as Apache Hadoop sometimes require high access density to maintain performance when running big data analytics applications. The most ideal capacities for these applications are 4TB, 6TB, and 8TB, and Western Digital's new product fits this description.
Through its new mid-range enterprise solution, Western Digital enables storage OEMs to maintain the integrity required by today's data center architectures by providing enterprise-grade performance and specifications. At the same time, OEMs can offer end users a variety of capacity and pricing options.
Available in 4TB and 6TB capacity options, the Ultrastar 7K6 is a quad disk product featuring enterprise-grade performance and an air-based design. It boasts up to 12% improved performance compared to the previous generation, the Ultrastar 7K6000. Furthermore, it is suitable for traditional storage and server applications, as well as distributed and scalable computing, including block and file storage architectures.
The Ultrastar 7K6 is currently available for product delivery for customer approval. At the end of the first quarter of 2018, the 8TB solution 'Ultrastar 7K8', featuring an Air-based design and Western Digital's 9th generation 5-disk platform, is also scheduled to be introduced.
Brendan Collins, Vice President of Western Digital’s Devices Business Unit, explained, “With the advancement of big data demanding higher capacity across various applications, mid-range applications have also begun shifting from 1TB and 2TB configurations to higher capacity ones. Western Digital’s new enterprise solution combines our technological prowess with our leadership in dramatically reducing the total cost of ownership for enterprises, enabling OEM manufacturers to provide data centers with a solution that allows them to manage big data in an on-premise environment without having to fully migrate it to the cloud.”
Available in 4TB, 6TB, and 8TB capacities, this new product features Western Digital's media cache and flash-based non-volatile cache to enhance write performance. It will be offered with SAS or SATA interfaces and meets enterprise-grade durability with a Mean Time Between Failures (MTBF) of 2 million hours. Preparations for expanding production volume are expected to be completed in the second quarter of 2018.
