• Fifth-generation Cheetah 15K is the fastest, highest capacity

and most reliable ever.

• 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% more IOPS and >20% faster response
times than 3.5-inch 10K drives.

• Cheetah 15K enables higher performance with fewer drives—

reducing support infrastructure, physical space requirements
and storage management costs.

• Cheetah 15K drives have the highest reliability of any 3.5-inch

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

• Optimal reliability and data protection continues to be a focus of

Seagate enterprise drives. Adding several new features in this
generation of Cheetah 15K has improved the nonrecoverable
error rate by a factor of 10.

• Seagate-exclusive IRAW (Idle Read After Write) enhances data

protection by verifying—during drive idle time—that data in the
drive buffer was properly written.

• Seagate-exclusive enhanced Error Correction Code better

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

• The second generation of Seagate-exclusive Background Media

Scan (BMS) proactively scans the media for potential defects
during drive idle time. It enables incipient errors to be corrected
before data is lost.

• The Cheetah 15K.5 is designed and manufactured by the same

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

• Certified, experienced support staff

• Rated “Above Average to Excellent” by 95% 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.
