2.5-INCH SFF ENTERPRISE 10K RPM HARD DISK DRIVES

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.

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.

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.

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.
