Big Performance and Capacity in a Small Package
HGST delivers the world’s fastest hard disk drive in the Ultrastar® C15K600, a 15K RPM, 2.5- inch small form factor hard drive ideally suited for mission-critical data center and high performance computing environments.Ultrastar C15K600 provides double the capacity of current generation 2.5-inch 15K drives, and matches the highest capacity point  of 3.5-inch 15K drives. This latest addition to the Ultrastar small form factor (SFF) family outperforms not only the competition but also legacy 3.5-inch 15K drives from HGST, achieving 38% faster sequential and 2.5X faster random write performance for faster data processing, while consuming half as much active and idle power.
Best-in-class performance is achieved through several innovations, including media caching technology that provides a large caching mechanism for incoming data resulting in significantly enhanced write performance over solutions with limited NAND or flashbased non-volatile cache (NVC). The C15K600 is HGST’s first hard drive to leverage an industry-leading 12Gb/s Serial-Attached SCSI (SAS) interface enabling very high transfer
rates between host and drive, supporting the performance and reliability required in the most demanding enterprise computing environments like on-line transaction processing (OLTP), big data analytics, multi-user applications and data warehousing.
