Big Performance and Capacity
Highlights
Power and Density Eꢀiciency
in a Small Package
• 15,000 RPM performance for Tier 0/1 applications
• Capacities up to 600GB1
The compact size and power management innovations
designed into the Ultrastar C15K600 enable high levels
of power eꢂiciency 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.
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.
• Industry-leading 12Gb/s SAS moves more data quickly
and reliably
• Compared to 15K 3.5-inch HDDs:
—2.5X faster random write performance
—14% faster random read performance
—38% faster sequential performance
—54% lower active and idle power
—70% smaller footprint
• 2M hours MTBF2 rating
• 128MB cache buffer manages data eꢀiciency
• Security & encryption models including ISE, TCGꢁSED &
FIPS 140ꢁ2 certiꢂied TCGꢁSED
Enterprise Reliability and Data
Security
Best-in-class performance is achieved through several
innovations, including media caching technology that
provides a large caching mechanism for incoming data
resulting in signiꢁicantly enhanced write performance
over solutions with limited NAND or ꢁlash-based
non-volatile cache (NVC). The C15K600 is HGST’s
ꢁirst 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.
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)
140ꢀ2 certiꢁication, 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.
