4.3Performance

•Firmware-controlled multisegmented cache designed to dynamically adjust segments for enhanced system performance

•600 MB/s maximum instantaneous data transfers

•15K RPM spindle. Average latency = 2.0 ms

•Background processing of queue

•Supports start and stop commands (spindle stops spinning)

•Adaptive seek velocity; improved seek performance

Note. There is no significant performance difference between Self-Encrypting Drive and standard (non- Self-Encrypting Drive) models.

4.4Reliability

•Annualized Failure Rate (AFR) of 0.44%

•Mean Time Between Failures (MTBF) of 2,000,000 hours

•Balanced low mass rotary voice coil actuator

•Incorporates industry-standard Self-Monitoring Analysis and Reporting Technology (S.M.A.R.T.)

•5-year warranty

4.5Formatted capacities

Standard OEM models are formatted to 512 bytes per block. The block size is selectable at format time and must be a multiple of 4 bytes. Users having the necessary equipment may modify the data block size before issuing a format command and obtain different formatted capacities than those listed.

To provide a stable target capacity environment and at the same time provide users with flexibility if they choose, Seagate recommends product planning in one of two modes:

Seagate designs capacity points at certain block sizes that Seagate guarantees current and future products will meet. We recommend customers use this capacity in their project planning, as it ensures a stable operating point with backward and forward compatibility from generation to generation. The current guaranteed operating points for this product are:
