4.4 Performance characteristics

Drive performance is characterized by the following parameters:
• Command overhead
• Mechanical head positioning
- Seek time
- Latency
• Data transfer speed
• Buffering operation (read ahead/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 system throughput, which depends on the system and the application.
The following table gives a typical value for each parameter. The detailed descriptions are found in Section 5.0, “Data integrity” beginning on page 21.
Table 4: Performance characteristics

Average random seek time - read (ms) 12 Average random seek time - write (ms) 14 Rotational speed (RPM) 4200 Power-on-to-ready (sec) 3.0 Command overhead (ms) 1.0 Disk-buffer data transfer (Mb/s) 350 Buffer-host data transfer (Mb/s) 100

4.4.1 Command overhead

Command overhead time is defined as the interval from the time that a drive receives a command to the time that the actuator starts its motion

4.4.2 Mechanical positioning

“Typical” and “Max” are used throughout this document and are defined as follows:
Typical Average of the drive population tested at nominal environmental and voltage conditions. Max Maximum value measured on any one drive over the full range of the environmental and voltage
conditions. (See Section 6.1, “Environment” on page 25 and Section 6.2, “DC power require­ments” on page 27 for ranges.)
The seek time is measured from the start of the actuator’s motion to the start of a reliable read or write operation. A reliable read or write implies that error correction or recovery is not used to correct arrival problems. The average seek time is measured as the weighted average of all possible seek combinations.
max
Σ (m10 n)(Tnin + Tnout)
n=1
Weighted Average = ––––––––––––––––––––––––––––
(max + 1)(max)
where
max = Maximum seek length n= Seek length (1 to max) Tnin = Inward measured seek time for an n track seek Tnout = Outward measured seek time for an n track seek
4.4.2.2 Full stroke seek time
Table 6: Full stroke seek time
Command type Typical (ms) Max (ms)
Read 23.0 30.0
Write 24.0 31.0
Full stroke seek is measured as the average of 1,000 full stroke seeks.
4.4.2.3 Single track seek time (without command overhead, including settling)
Table 7: Single track seek time
Command type Typical (ms) Max (ms)
Read 2.5 4.0

Single track seek is measured as the average of one (1) single track seek from every track in both directions (inward and outward).

Performance Idle
electronic components remain powered and the full frequency servo remains opera­tional.
The device is capable of responding immediately to media access requests. Some cir­cuitry—including servo system and R/W electronics—is in power saving mode. The
Active idle
head is parked near the mid-diameter the disk without servoing. A device in Active idle mode may take longer to complete the execution of a command because it must activate that circuitry.
Low power idle
The head is unloaded onto the ramp position. The spindle motor is rotating at full speed.

Table 10: Description of operating modes
Operating mode Description
The device interface is capable of accepting commands. The spindle motor is stopped.
Standby
All circuitry but the host interface is in power saving mode. The spindle motor is stopped. All circuitry but the host interface is in power saving mode.
Sleep
The device requires a soft reset or a hard reset to be activated. All electronics, includ­ing spindle motor and host interface, are shut off.

4.4.3.3 Operating mode at power on
The device goes into Idle mode after power on or hard reset as an initial state. Initial state may be changed to Standby mode using pin C on the interface connector. Refer to section 7.10, “Drive address setting” on page 55 for details.
4.4.3.4 Adaptive power save control
The transient timing from Performance Idle mode to Active Idle mode and Active Idle mode to Low Power Idle mode is controlled adaptively according to the access pattern of the host system. The transient timing from Low Power Idle mode to Standby mode is also controlled adaptively, if it is allowed by Set Features Enable Adavanced Power Management subcommand.
