Data buffer transfer rate to/from disc media (one 512-byte sector):

Sustainable disc transfer rate:

1 Megabyte (MB) = 1,000,000 bytes. 

[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.

Sector Sizes

Default is 512-byte data blocks.

Logical block sizes

Default is 512-byte data blocks

 

512, 520, 524, and 528 supported.

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.
