Cheetah 15K.6 SAS Product Manual, Rev. B

When changing sector sizes, the format times shown below may need to be increased by 30 minutes.     

There is no significant difference in the format time between FDE and non-FDE models of the same 
capacity.

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).

The drive accepts the commands listed in the SAS Interface Manual less than 3 seconds after DC power has 
been applied.

If the drive receives a NOTIFY (ENABLE SPINUP) primitive through either port and has not received a START 
STOP UNIT command with the START bit equal to 0, the drive becomes ready for normal operations within 20 
seconds (excluding the error recovery procedure).
