3.3 Cylinder Allocation
Mode page 03 (Format Device Parameters) and 0C (Notch Parameters) provide methods to determin
medium format and zone parameters. See 7.9.6, “Page 3 (Format Device Parameters)” on page 102, and
7.9.11, “Page 0C (Notch Parameters)” on page 110.
3.4 Performance Characteristics
A drive performance is characterized by the following parameters:
Command Overhead
Mechanical Positioning
− Seek Time
− Latency
Data Transfer Speed
Buffering Operation (Lookahead/Write cache)
Note: All the above parameters contribute to drive performance. There are other parameters that contribute
to the performance of the actual system. This specification tries to define the bare drive characteristics, not
the system throughput which will depend on the system and the application.
