• Cheetah 15K performance and reliability enable lower

TCO for a wide variety of enterprise applications.

• Cheetah 15K RPM and fast seek times deliver the

fastest time-to-data, resulting in 30 percent more IOPS
and more than 20 percent faster response times than
3.5-inch 10K drives.

• Cheetah 15K enables higher performance with fewer

drives. Fewer drives reduce support infrastructure,
physical space requirements and storage management
costs.

• Cheetah 15K drives have the highest field-proven

reliability in the industry and further increase system
reliability due to the need for fewer drives.

• This fourth-generation Cheetah 15K is the fastest,

coolest, quietest and most reliable ever.

• Seagate-exclusive enhanced Error Correction Code

better maintains performance throughout the life of the
drive and reduces the probability of lost data.

• Background Media Scan, a Seagate exclusive feature,

proactively scans the media for potential defects during
drive idle time without using system bandwidth. It
enables incipient errors to be corrected before data is
lost.

• The Cheetah 15K.4 is designed and manufactured by

the same teams that successfully delivered the past
three award-winning generations of Cheetah 15K.

• Certified, experienced support staff

• Rated “Above Average to Excellent” by 95 percent of

our customers

• Support lines with the shortest wait times in the industry

• Individually archived case histories for quick reference

• Web-based Q&A forum and autoreply e-mail

• Seagate Design Service Centers (DSC) help companies

transform innovative ideas into viable products.
