Generalized performance characteristics

Sector interleave
Data buffer transfer rate to/from disc media (one 512-byte sector):
Min. [4]* 13.7 MByte/sec
Avg. [4] 19.9 MByte/sec
Max. [4] 23.8 MByte/sec
Data buffer transfer rate to/from disc media: (< 1 track):
Min. [4] 10.5 MByte/sec
Avg. [4] 15.2 MByte/sec
Max. [4] 18.3 MByte/sec
SCSI interface data transfer rate (asynchronous) [5]:
Maximum instantaneous
Maximum average
Synchronous transfer rate for SCSI-3 Fast-20 (Ultra-1 SCSI):
(8 bit data bus models)
(16 bit data bus models)
Synchronous transfer rate for SCSI-3 Fast-40 (Ultra-2 SCSI):
(8 bit data bus models)
(16 bit data bus models)
Synchronous transfer rate for fast SCSI-2:
(8 bit data bus models)
Synchronous transfer rate for fast SCSI-2:
(16 bit data bus models).
Sector Sizes:
Read/write consecutive sectors on a track
Flaw reallocation performance impact (for flaws reallocated at format time,
all P and G list entries will be slipped).
Overhead time for head switch (512 byte sectors) in sequential mode
Overhead time for one track cylinder seek (cylinder skew)
Average rotational latency
