Specifications subject to change without notice. All specifications are based on an 11W performance level.
* Performance may vary by capacity.
(1) Based on direct attached SAS performance testing, performance may be lower depending upon host device, OS and application.
(2) 1 gigabyte (GB) = 1 billion bytes. Some capacity not available for data storage.
(3) MTBF – Mean Time Between Failures based on parts stress analysis.
(4) The earlier of (I) five (5) years or (II) the time at which such Product unit’s total cumulative data recorded on such unit at its S.M.A.R.T. attribute (log page
2Fh, parameter 25) or log page 11h, parameter 1 (Percentage Used Endurance Indicator) reaches 100% of the Product unit’s endurance value. For more
