Big Capacity and Performance
in a Small Package
HGST delivers best-in-class capacity and performance in
one small form factor hard drive. The Ultrastar® C10K1800
is a 10K RPM enterprise-class HDD that stores up to 1.8TB
of data, 50% more capacity than prior generations, plus
delivers best-in-class active and idle power efficiency,
enabling next generation data centers to keep pace
with digital data growth and improve space and power
efficiencies. Data center architects can also leverage best-
in-class performance on the C10K1800, achieving up to 2.5X
better random write performance and 23% faster sequential
performance over prior generation 2.5-inch SFF 10K RPM
HDDs for demanding 24x7 enterprise workloads.
Enterprise Security and
Reliability
The Ultrastar C10K1800 offers the broadest range of
encryption and security options available on SAS HDDs from
HGST, including Trusted Computing Group (TCG) enterprise
SSC-compliant Self-Encrypting Drives (SED) which provide
data protection without any performance loss, and TCG
with FIPS (Federal Information Processing Standard) 140-2
certification, which adds and tamper evidence protection
for the most stringent regulatory data security compliance
requirements. Instant Secure Erase (ISE) models enable fast,
cost-effective and secure drive repurposing and retirement.
C10K1800 extends the company’s long-standing tradition
of reliability leadership with a 2M hours MTBF rating and a
5-year limited warranty.
Technology Innovation
Ultrastar C10K1800 delivers unmatched performance
thanks to several HGST technology innovations including
media cache architecture, the industry’s fastest 12Gb/s
Serial-Attached SCSI (SAS) interface and advanced format
options. HGST’s media cache architecture is a disk-based
caching technology, which provides a large non-volatile
cache on the media resulting in improved reliability and
data integrity during unexpected power loss, as well as a
significant improvement in write performance even at high
workloads when compared to solutions with limited NAND
or flash-based NVC. The C10K1800 is the industry’s first
10K RPM drive to leverage an industry-leading 12Gb/s SAS
interface, enabling very high transfer rates between host and
drive. Advanced format models enable the industry’s highest
10K RPM capacity at 1.8TB with 4K native and 512 emulation
to support new systems, and also offers 512 native format
models to support legacy systems.
HGST Quality and Service
The Ultrastar C10K1800 extends the long-standing HGST
tradition of performance and reliability leadership. A
balanced combination of new and proven technologies
helps ensure high reliability and availability of customer data.
HGST drives are backed by an array of technical support
and services, which may include customer and integration
assistance. HGST is dedicated to providing a breadth of
hard disk drive solutions to satisfy all of today’s demanding
computing needs.

1 One MB is equal to on million bytes, one GB is equal
to one billion bytes and one TB equals 1,000GB (one
trillion bytes) when referring to hard drive capacity.
Accessible capacity will vary from the stated capacity
due to formatting and partitioning of the hard drive, the
computer’s operating system, and other factors.
2 MTBF and AFR targets are based on a sample
population and are estimated by statistical
measurements and acceleration algorithms under
median operating conditions. MTBF and AFR ratings
do not predict an individual drive’s reliability and do not
constitute a warranty.
