摘要

Over the past decades, the amount of digital information is increasing tenfold every five years. According to a report prepared by International Data Corporation (IDC) in 2014, the total amount of digital data generated globally will reach 44 ZB (1 ZB = 10~3, EB = 10~6, PB = 10~(12)GB) by 2020 . Hard drives are the most inexpensive devices used to store digital information that is infrequently accessed and stored for a long time. Hard drives, like magnetic tapes, have large storage capacity, however they are physically larger in size and slower in speed than the solid-state drives (SSD). Moreover, they have movable parts, which makes them more prone to damage and read/write errors.
