Hitachi Takes on the Savvio

With today's introduction of its Ultrastar C10K147, Hitachi throws its hat into the 2.5" "small form factor" (SFF) arena and joins competing products from Seagate and Fujitsu.

In part driven by the continuing maturation and acceptance of the SAS interface (which continues to displace the disparate 80-pin SCA-style and 68-pin SCSI connector styles with a new unified standard), Hitachi's entry into the game further bolsters the view that the future of enterprise storage rests in the 2.5" form factor.

Ultrastar C10K147 Hard Drive’s Compact Size Optimized for Space & Power for Data Centers

SAN JOSE, Calif. – June 28, 2007 – Timed to capitalize on the fast ramp of small form factor (SFF) enterprise hard drives in 2007, Hitachi announced today it has shipped the Ultrastar® C10K147 hard drive, the company’s first SFF enterprise product. The 10,000 RPM Ultrastar C10K147 hard drive was developed specifically for high-performance and low-power requirements of servers, delivering up to 147GB1 of capacity and 3Gb/s Serial Attached SCSI (SAS) interface.

With the Ultrastar C10K147 hard drive, Hitachi expands its enterprise segment participation with a broad and expanded portfolio. Along with the SFF hard drive, Hitachi’s portfolio includes the 15,000 RPM 3.5” Ultrastar 15K300 and 10,000 RPM 3.5-inch Ultrastar 10K300 hard drives for mission-critical storage and the 7,200 RPM 3.5-inch Ultrastar A7K1000 one-terabyte hard drive for lower duty-cycle enterprise applications. All three products are shipping now.

Space, Power Requirements Drive Small Form Factor Transition

Enterprise customers are increasingly seeking solutions to reduce space and power requirements in data centers. Coupled with a new interest in establishing government mandates for “green” data centers, a transition to small form factor hard drives from the traditional 3.5” drives previously used in servers is gaining a new sense of urgency. 2007 has been predicted by industry analysts as a turning point in the volume ramp of small form factor enterprise hard drives.

The Ultrastar C10K147 hard drive provides a 50 percent smaller foot print and a 40 percent reduction in z-height over traditional enterprise hard drives. This compact size provides optimal space and power efficiencies while still delivering high performance with 10,000 RPM spin speed, high-speed SAS interface and 16MB data buffer. These features combine to make the Ultrastar C10K147 hard drive ideally suited for blade servers and 1U and 2U rack-mounted servers for mission-critical applications.

“With volume availability of our Ultrastar C10K147, we have delivered on our expanded 2007 enterprise product portfolio. The introduction of a small form factor enterprise hard drive and our milestone one-terabyte drive add depth to our enterprise HDD line-up and allow us to further penetrate this segment with a broader range of solutions to address our customers’ needs,” said Currie Munce, vice president, Enterprise HDD Business Group, Hitachi Global Storage Technologies.
