HGST announced the launch of a new family of 15K RPM 12Gb/s SAS hard drives

HGST, Western Digital company, announced the launch of its new family of high-performance, high-capacity, 2.5-inch small form factor (SFF), 15K RPM enterprise-class hard disk drives (HDD).

The Ultrastar C15K600 family enables higher density and higher performing servers, blades and network storage arrays all while reducing space requirements, lowering cooling costs and improving total cost of ownership (TCO).

Tha hard drives use HGST's media caching technology, which provides a large caching mechanism for incoming data resulting in significantly enhanced write performance over solutions with limited NAND or flash-based non-volatile cache (NVC).It is the only 2.5-inch enterprise-class HDD family to feature a SAS 12Gb/s interface for reliable data throughput and a 128MB cache buffer for optimized read/write response time for reliable high-performance computing.

The Ultrastar C15K600 has a 600GB capacity, and its 2.5-inch SFF, along with HGST Advanced Power Management technology, provides up to a 55 percent improvement in active power and 54 percent improvement in idle power consumption over HGST's current 3.5-inch 15K HDDs.

HGST estimates that, by 2016, the Performance Enterprise (15K and 10K) HDD Total Available Market (TAM) will be more than two times the unit size of the Enterprise SSD TAM. This way, the 15K Ultrastar C15K600 family will get to be offered in 512e, 512n and 4K Advanced Format.

"A couple of factors are keeping the demand strong for 15K HDDs," said Brendan Collins, vice president of product marketing, HGST. "First, our customers continue to use 15K HDDs along with a complement of SSDs in tiered pools of storage, depending on their performance, capacity, and power efficiency requirements. Our new Ultrastar C15K600 fills a need for storage that is more cost effective than SSDs, and has the performance, reliability and capacity requirements needed by mission-critical enterprise applications.  Also, we see that the industry is transitioning away from 15K 3.5-inch hard drives to smaller 2.5-inch drives to help reduce space requirements, while offering comparable capacities to the legacy 3.5-inch 15K products."

The new Ultrastar C15K600 SAS 15K HDD family offers 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 512n and 4Kn versions of the Ultrastar C15K600 hard drive family are now available, while the 512e version will be available this summer. All of the hard drives come with a five-year limited warranty.
