4.2.2 Format command execution time ST973451FC ST936751FC Maximum (with verify) 52 minutes 26 minutes Maximum (without verify) 35 minutes 18 minutes 4.2.3 General performance characteristics Sustained transfer rate 79 to 112 Mbytes/sec Fibre Channel Interface maximum instantaneous transfer rate 400 Mbytes/sec* per port (dual port = 800 Mbytes/sec*) Logical block sizes - 512 (default) - 520 - 524 - 528 Read/write consecutive sectors on a track Yes Flaw reallocation performance impact (for flaws reallocated at format time Negligible using the spare sectors per sparing zone reallocation scheme.) Average rotational latency 2.0 msec *Assumes no errors and no relocated logical blocks. Rate measured from the start of the first logical block transfer to or from the host. 4.3 Start/stop time 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). If the drive receives a START STOP UNIT command with the START bit equal to 0 before receiving a NOTIFY (ENABLE SPINUP) primitive, the drive waits for a START STOP UNIT command with the START bit equal to 1. After receiving a START STOP UNIT command with the START bit equal to 1, the drive waits for a NOTIFY (ENABLE SPINUP) primitive. After receiving a NOTIFY (ENABLE SPINUP) primitive through either port, the drive becomes ready for normal operations within 20 seconds (excluding the error recovery procedure). If the drive receives a START STOP UNIT command with the START bit and IMMED bit equal to 1 and does not receive a NOTIFY (ENABLE SPINUP) primitive within 5 seconds, the drive fails the START STOP UNIT command. 12 Savvio 15K.1 FC Product Manual, Rev.
