HGST Ships 1.8 TB 10K Hard Disk Drive
Western Digital's HGST is now shipping the Ultrastar C10K1800, a 10000 RPM hard drive in the 2.5-inch small form factor targeting enterprise / data center applications. While solid state drives (SSDs) and 15K HDDs fill a clear need in high performance solutions, the demand for 10K HDDs continues to be strong as customers seek better $/GB metrics.
Powered by several technologies including HGST's media cache architecture, an upgraded 12Gbps SAS interface and advanced format options, the Ultrastar C10K1800 delivers improvements in performance and reliability. Most notably is HGST's media cache architecture - a disk-based caching technology, which provides a large non-volatile cache on the media resulting in improved reliability and data integrity during unexpected power loss, as well as an improvement in write performance even at high workloads when compared to solutions with limited NAND or flash-based NVC.
HGST claims the Ultrastar C10K1800 provides a boost of up to 2.5X in random write performance and a 23 percent improvement in sequential performance over prior generation 2.5-inch SFF 10K HDDs.
The hard drive family comes with both 4K native / 512 emulation and a 512 native sectors version for legacy compatibility.
Its 12Gbps SAS interface provides twice the bandwidth of existing 6Gbps SAS interface, while it remains backwards compatibile with existing devices and enclosures.
A host of security and encryption options including Instant Secure Erase (ISE), Trusted Computing Group (TCG) enterprise SSC-compliant Self-Encrypting Drives (SED), and TCG enterprise SED with FIPS (Federal Information Processing Standard) 140-2 certification, Level 2.
The Ultrastar C10K1800 HDD family delivers 2M hours MTBF, an annualize failure rate (AFR) of 0.44 percent and comes with a five-year limited warranty. It is shipping now, but the FIPS certified models will be available in January 2015.
Complementing the new Ultrastar C10K1800 HDD family, HGST also announced today that the 512 emulation format for its 15K enterprise-class Ultrastar C15K600 product family will be shipping in July.
