Western Digital Ultrastar 7K6 3.5″ 4000 GB Serial ATA III

Description

Ultrastar DC HC310 is based on a new 4-disk air platform design that

uses conventional magnetic recording (CMR) technology in a 3.5-inch

large form factor. Compared to the prior generation, Ultrastar 7K6000,

the DC HC310 delivers a 12% performance boost and uses slightly

larger-diameter media. It features a second-generation, dual-stage

micro actuator to enhance head positioning accuracy for better drive

performance. Write performance gains are also supported by Western

Digitals media cache architecture, a disk-based caching technology that

provides a large cache area on the disk, which also improves reliability

and data integrity during unexpected power loss. Finally, the addition

of fl ash-based non-volatile cache (NVC) on both SATA and SAS models

helps improve write performance. The Ultrastar DC HC310 also includes

a Rebuild Assist feature, which helps dramatically reduce RAID rebuild

times and maintain system performance during the rebuild process.
