Highest Reliability
• 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.
