4.2.2 Format command execution time for Š 512-byte sectors (minutes) ST973401FC ST936701FC Maximum (with verify) 52 26 Maximum (without verify) 26 13 4.2.3 General performance characteristics Minimum sector interleave 1 to 1 Data buffer to/from disc media (one 512-byte logical block)* Minimum Maximum 63 Mbytes/sec 94 Mbytes/sec Fibre Channel Interface maximum instantaneous transfer rate 200 Mbytes/sec* per port (dual port = 400 Mbytes/sec*) Logical block sizes Default is 512-byte data blocks Variable 512 to 704 bytes per sector in even number of bytes per sector. If n (number of bytes per sector) is odd, then n-1 will be used. 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 3.0 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 If the Motor Start option is disabled, the drive becomes ready within 20 seconds after DC power is applied. If a recoverable error condition is detected during the start sequence, the drive executes a recovery procedure and the time to become ready may exceed 20 seconds. Stop time is 30 seconds (maximum) from removal of DC power. If the Motor Start option is enabled, the internal controller accepts the commands listed in the Fibre Channel Interface Manual less than 3 seconds after DC power has been applied. After the Motor Start command has been received, the drive becomes ready for normal operations within 20 seconds (excluding the error recovery procedure). The Motor Start command can also be used to command the drive to stop the spindle. There is no power control switch on the drive. 12 Savvio FC Product Manual, Rev. D
