Lowest Cost of Ownership
• 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.

Highest Reliability
• 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 non-recoverable
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.
