123

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.

Minimum sector interleave

1 to 1

Data buffer to/from disk media (one 512-byte logical block)*

1.44 to 2.35 Gb/s

Sustained transfer rate

119 to 195 MiB/s ** 

125 to 204 MB/s

SAS Interface maximum instantaneous transfer rate

600 MB/s* per port 

(dual port = 1200 MB/s*)

Logical block sizes

512 (default), 520, 524 or 528.

Read/write consecutive sectors on a track

Yes

Flaw reallocation performance impact (for flaws reallocated at format time using the 

spare sectors per sparing zone reallocation scheme.)

Negligible

Average rotational latency

2.9ms

*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
