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.
