• The Cheetah

®

10K.7 uses a fluid dynamic bearing (FDB)

motor, the same technology used by the Cheetah 15K.
FDB reduces the drive’s acoustics and improves
reliability with the removal of ball bearings in the motor.

• Seagate-exclusive enhanced Error Correction Code

better maintains performance throughout the life of the
drive and improves reliability by decreasing the bit error
rate, resulting in a lower probability of lost data.

• Background Media Scan, a Seagate-exclusive feature,

scans the media for potential defects during drive idle
time—rather than in the midst of trying to complete a
customer’s read/write request—without using system
bandwidth. It enables incipient errors to be corrected
before data is lost.

• The Cheetah 10K.7 is designed and manufactured by

the same teams that successfully delivered the past six
award-winning generations of Cheetah.

• 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
