Western Digital Corporation expands its portfolio for enterprise customers with a new, mid-range series of 4 terabyte (TB), 6TB and 8TB air-based hard drives. The new products enable data centers having data set sizes smaller than found in hyperscale environments.
The specifications are common, RPM is 7,200 rpm, the cache capacity is 256 MB, the maximum transfer speed is 255 MB/sec, the seek time is 8.0 ms, the write is 8.6 ms. The loading and unloading cycle is 600,000 times, the MTBF is 2 million hours, the product warranty is 5 years.
"The power of Big Data is driving the need for higher capacities across a broad spectrum of applications," said Brendan Collins, vice president of marketing, Devices Business Unit, Western Digital. "Today, mid-range applications are preparing to move from 1TB and 2TB configurations to higher capacities. Our new enterprise solutions blend the technology and TCO leadership of Western Digital's capacity enterprise product line with a high-density, air-based hard drive design, allowing OEMs to offer data centers a solution to keep Big Data on-premises, rather than transition entirely to the cloud."
Distributed file systems such as Apache Hadoop often have workloads that require higher access density in order to maintain performance when running Big Data analytics jobs. The "sweet spot" capacities for these applications are 4TB, 6TB and 8TB. Western Digital's new enterprise solutions are designed for this space, while providing enterprise-level performance and specifications for storage OEM partners to serve end customers with a range of capacity and price points while maintaining the enterprise integrity demanded by today's data center architects.
Available immediately for qualification, the new Ultrastar 7K6, supporting 4TB and 6TB capacity points, utilizes a new 4-disk, enterprise class, air-based design. The new products provide up to 12 percent faster performance than the prior generation Ultrastar 7K6000 and is designed for traditional storage and server applications as well as distributed and scalable computing, including block-and-file storage architecture. Later this quarter, the company will deliver an Ultrastar 7K8 8TB solution, which is based on an air-based design and is the ninth generation of the company's 5-disk platform. Further information regarding the Ultrastar 7K6 and 7K8 is available on the website.
The 4TB, 6TB and 8TB offerings will be ready for volume ramp during the second calendar quarter of 2018. Western Digital's media cache and flash-based non-volatile cache (NVC) are implemented to improve write performance. These new enterprise drives will be available in either SAS or SATA interfaces and provide an enterprise-class MTBF rating of 2M hours.
