Sustainable disc transfer rate: 

SCSI interface data transfer rate (asynchronous): 

Synchronous transfer rate  

Sector Sizes:

  Default

512 byte user data blocks

  Variable

512 to 528 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.  

Notes for Section 5.2.

[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]

Assumes no errors and no sector has been relocated.

[3]

Assumes system ability to support the rates listed and no cable loss.

1.

Typical access times are measured under nominal conditions of temperature, volt-
age, and horizontal orientation as measured on a representative sample of drives.

2.

Access to data = access time + latency time.
