  • the disk controllers 206a and 206b grasp the state of the HDD 6 (whether it is in the sleep state or the start state), and switch the state of the HDD 6 between the sleep state and the start state as necessary. For example, the disk controller 206b switches the HDD 6 from the sleep state to the activated state when (read or write) access to the HDD 6 occurs while the HDD 6 is in the sleep state. In this case, the disk controller 206b returns the HDD 6 from the activated state to the sleep state after maintaining the activated state for a predetermined time after switching to the activated state (that is, after the predetermined time has elapsed). This is to avoid frequent spin-up and spin-down of the HDD 6 as will be described later.

  • FIG. 4 is a diagram illustrating an example of the operation of a general HDD.
  • the HDD has a sleep state (power limit state) and an activation state. While power is supplied to the HDD in the activated state, the supply of power to the HDD is restricted in the sleep state, and the power consumption of the HDD is kept lower than that in the activated state. For this reason, it is possible to reduce the power consumption of the device (MFP 1 in this embodiment) in which the HDD is mounted by keeping the HDD in the sleep state as much as possible.
  • the so-called power limit states of the SATA compatible HDD and SSD include, for example, the following modes (“PHY Ready (PHYRDY)”, “Partial”, and “Slumber”).
  • PHY Ready The PHY (physical layer) defined by the SATA standard is in a state where data can be transmitted and received.
  • Partial PHY is in a reduced power mode. A return time of up to 10 microseconds is allowed.
  • Slumber PHY is a power saving state with lower power consumption than the Partial mode. The return time is a maximum of 10 milliseconds.
  • the return time is the maximum time from when a product compliant with the SATA standard receives a wake-up signal to return to the PHYRDY mode.
  • the HDD when (read or write) access to the HDD in the sleep state occurs (401), the HDD is switched from the sleep state to the activated state. Specifically, when the restriction on power supply is released, the HDD performs spin-up (starts disk rotation), and reaches an activated state after a certain time (for example, 2 to 10 seconds) elapses. When the HDD is activated, the HDD can be accessed. Thereafter, when a certain amount of time has elapsed, the HDD is switched from the activated state to the sleep state in order to reduce power consumption (402). Specifically, the HDD stops rotating the disk by performing spin down. Furthermore, the supply of power to the HDD is limited, so that the HDD enters a sleep state.
  • HDDs as described above generally have a limited number of times that spin-up and spin-down (start and stop) can be performed. For example, spin-up and spin-down can be executed up to about 300,000 times for a 2.5-inch HDD and about 100,000 times for a 3.5-inch HDD. For this reason, HDD spin-up and spin-down affect the life of the HDD (that is, the period until the HDD fails). That is, if the HDD spin-up and spin-down are frequently executed, the period until the HDD fails is shortened.
  • control is continued to maintain the startup state.
  • this control increases the power consumption of the HDD, leading to an increase in the power consumption of the device in which the HDD is mounted.
  • control may be performed to maintain the startup state for a certain period of time (for example, 10 minutes for a 2.5-inch HDD and 30 minutes for a 3.5-inch HDD).
  • extra power is consumed in the HDD by maintaining the HDD in the activated state during a period when no access to the HDD occurs.
