The Cheetah 15K.4 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. It maintains performance throughout the life of the drive and reduces the probability of lost data. No ball bearings means reduced acoustics and improved reliability.
