3.3 Performance Characteristics
A file performance is characterized by the following parameters:
Command Overhead
Mechanical Positioning
−Seek Time
−Latency
Data Transfer Speed
Buffering Operation (Look ahead/Write cache)
Note: All the above parameters contribute to file performance. There are other parameters that contribute
to the performance of the actual system. This specification tries to define the bare file characteristics, not the
system throughput which will depends on the system and the application.
3.3.1 Command Overhead
Command overhead is defined as the time required:
from the command is written into the command register by a host
to the assertion of DRQ for the first data byte of a READ command when the requested data is not in
the buffer
exclude
−Physical seek time
−Latency time

Note: The above table gives an average time.

Drive Characteristics 9

Max Maximum value measured on any one drive over the full range of the environmental and
voltage conditions. (See section on Environment and D.C. Power Requirement.)
The seek time is measured from the start of motion of the actuator until a reliable read or write operation
may be started. Reliable read or write implies that error correction/recovery is not employed to correct for
arrival problems. The Average Seek Time is measured as the weighted average of all possible seek combina-
tions.

3.3.2.2 Full Stroke Seek (Without Command Overhead, Including Settling)
Figure 5. Full Stroke Seek Time
Full stroke seek is measured as the average of 1000 full stroke seeks with a random head switch from both
directions (inward and outward).
3.3.2.3 Head Switch Time (Head Skew)
Figure 6. Head Switch Time
A head switch time is defined as the amount of time required by the fixed disk to complete seek the next
sequential track after reading the last sector in the current track.
The measurement method is given in 3.3.5, “Throughput” on page 13.

A cylinder switch time is defined as the amount of time required by the fixed disk to complete seek the next
sequential block after reading the last track in the current cylinder.
The measurement method is given in 3.3.5, “Throughput” on page 13.
3.3.2.5 Single Track Seek Time (Without Command Overhead, Including Settling)
Figure 8. Single Track Seek Time
Single track seek is measured as the average of one (1) single track seek from every track with a random head
switch in both direction (inward and outward).
3.3.2.6 Average Latency
Figure 9. Latency Time
3.3.3 Drive Ready Time

Ready The condition in which the drive is able to perform a media access command (e.g.
read, write) immediately.

Device 1 to assert -PDIAG.

3.3.4 Data Transfer Speed
Figure 11. Data Transfer Speed
Instantaneous Disk-Buffer Transfer Rate (Mbyte/sec) is derived by:
(Number of Sectors on a track) * 512 * (Revolution/sec)
Note: Number of sectors per track will vary because of the linear density recording.
Sustained Disk-Buffer Transfer Rate (Mbyte/sec) is defined by considering head/cylinder change time.
This gives a local average data transfer rate. It is derived by:
(Sustained Transfer Rate) = A/ (B+C+D)
A = (Number of Data Sectors per Cylinder) * 512
B = (# of Surface per cylinder) - 1) * (Head Switch Time)
C = (Cylinder Change Time)
D = (# of Surface) * (One Revolution Time)
Instantaneous Buffer-Host Transfer Rate (Mbyte/sec) defines the maximum data transfer rate on AT
Bus. It also depends on the speed of the host.
The measurement method is given in 3.3.5, “Throughput” on page 13.
