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. At 600GB, 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 flash-
based 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.
Power and Density Efficiency
The compact size and power management innovations designed into the Ultrastar
C15K600 enable high levels of power efficiency and translate into reduced power
requirements and lower cooling costs, an ideal choice for enterprise data centers faced
with space and power limitations. Compared to legacy 3.5-inch 15K drives, Ultrastar
C15K600 consumes 70% less space yet provides up to 55% lower active power and 54%
lower idle power requirements. HGST Advanced Power Management technology, with
multi-state idle modes, uses industry-recognized standards for power optimization and
can be pre-programmed or manually initiated in the system.
Enterprise Reliability and Data Security
The Ultrastar C15K600 offers the broadest range of security options and encryption
options available from HGST, including 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, which
provides data-at-rest and tamper evidence protection for the most stringent regulatory
data security compliance requirements. Ultrastar C15K600 extends the company’s long-
standing tradition of reliability leadership with a 2M hour MTBF rating, an annualized
failure rate (AFR) of 0.44% and a 5-year limited warranty.
