4.2.2Format command execution time (minutes)

	ST3400755FC	ST3300955FC
Maximum (with verify)	180	140
Maximum (without verify)	100	80

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).

4.2.3	General performance characteristics
Sustainable disc transfer rate*:
Minimum		54 Mbytes/sec
Maximum		97 Mbytes/sec
Fibre Channel Interface maximum instantaneous transfer rate		800 Mbytes/sec* per port
		(dual port = 1600 Mbytes/sec*)
Logical block sizes
Default is 512-byte data blocks
Sector sizes variable to 512, 520, 524 and 528 bytes.
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.)

*Assumes no errors and no relocated logical blocks. Rate measured from the start of the first logical block transfer to or from the host.

4.3Start/stop time

The drive accepts the commands listed in the Fibre Channel 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 30 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 30 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.

The START STOP UNIT command may be used to command the drive to stop the spindle. Stop time is 30 sec- onds (maximum) from removal of DC power.

There is no power control switch on the drive.
