Seek performance characteristics

4.2.1

Format command execution time for 512-byte sectors (minutes)

Maximum (with verify)
Maximum (without verify)
Execution time measured from receipt of the last byte of the Command Descriptor Block (CDB) to the request for a Status Byte Transfer to
the Initiator (excluding connect/disconnect).
When changing sector sizes, the format times shown above may need to be increased by 30 minutes.
4.2.2

General performance characteristics

Sustained transfer rate
SAS Interface maximum instantaneous transfer rate
Logical block sizes
512 (default), 520, 524 and 528
4k - 4096 (default), 4160, 4192, and 4224
Read/write consecutive sectors on a track
Flaw reallocation performance impact (for flaws reallocated at format time using the
spare sectors per sparing zone reallocation scheme.)
Average rotational latency
* Assumes no errors and no relocated logical blocks. Rate measured from the start of the first logical block transfer to or
from the host.
** MiB/s x 1.048 = MB/s
