4.2.3 Generalized performance characteristics
Data buffer transfer rate to/from disc media (one 512-byte sector):
Sustainable disc transfer rate:
Note. 1 Megabyte (MB) = 1,000,000 bytes.
Notes for Section 4.2.
[1] 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).
[2] Typical access times are measured under nominal conditions of temperature, voltage, and horizontal ori-
entation as measured on a representative sample of drives.
[3] Assumes system ability to support the rates listed and no cable loss.
[4] Access to data = access time + latency time.
