Format command execution time (minutes)

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

Note.

There is approximately a 1.5 increase in time to format a SED drive versus a non-SED drive 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).

Access to data = access time + latency time.
