SURVEY ON RELIABILITY OF SOLID-STATE-DRIVE BASED STORAGE SYSTEMS
Keywords:
Solid-state-drive, RAID, Reliability, P/Ecycle (program/erase)Abstract
Solid-state-drives based RAID is a group of solid-state-drives, which are protected by using the parity disks. If
the program and erasecycles raises, the stoppage probability in solid-state-drive alsoraises. Depending up on how the parity
allotmentis happening among the solid-state-drive, the reliability of the solid-state-drive gets changes. Evenly or unevenly we
can allot theparities among solid-state-drive based RAIDs. In even parity allotment, all the solid-state-drives tire out with the
same rate which escort to simultaneous failure of solid-state-drives. In odd parity allotment, either one of thesolid-state-drive
in RAID might get fail prior to any other drive. The problems such as Simultaneous failure of solid-state-drives andfailure of
one of the solid-state drive prior to any other drive will become the drawbacksof solid-state-drive with RAID as they reduce
the reliability of solid-state-drives based RAIDs. These drawbacks can be overcome by using Hybrid RAID. This Hybrid
RAID alters the allotment of parity when the number of P/E cycle reaches to some predefined limit.
