New Hard Drives: Small and Powerful

Arthur Cole

New enterprise storage solutions continue to combine smaller form factors with high performance and low power requirements.


The latest development comes from Hitachi in the form of three new additions to its Ultrastar hard drive line. The new devices range from the 15K300, the A7K1000 and the C10K147, which the company bills as the first small form factor (SFF) enterprise-class drive.


The company is placing its highest hopes on the C10K147 to address both the space and energy consumption concerns that are driving most data center investment today. The unit offers 147 GB in a 2.5-inch drive spinning at only 10,000 RPM. It provides a 16 MB buffer and a 3 Gbps SAS interface. Expect to see it play a role in HP blades in the near future.


The other two drives, the 15K300 and the A7K1000, are 3.5-inch devices running at 15,000 RPM and 7,200 RPM, respectively. The 15K300 delivers 300 GB with Ultra320 SCSI, 3Gbps SAS and 4 Gbps FCAL interfaces, while the A7K1000 provides 1 TB with a 3 Gbps SATA interface.
