Description

Storage device with multiple storage units and control method thereof

technical field

The invention relates to a storage device with multiple storage units and its control method, especially to a storage device with at least two storage units, one of which is a memory storage unit.

Background technique

Personal computers use Hard Disk Drive (HDD for short) as the loading device for the operating system, which uses a non-volatile (non-volatile) storage device based on a hard rotating disk, and is mounted on a flat magnetic surface. Store and retrieve digital data. Information is written to the disk by electromagnetic currents that change the polarity of the magnetic head through a head that is very close to the magnetic surface. Information can be read back by the opposite way, such as a magnetic field causing a change in electricity in a coil or a head passing over it.

And along with the development of various electronic products, hard drives have developed various standard sizes for application in these electronic products, for example: 0.85 inches, which are mostly used in portable devices such as mobile phones. 1 inch (micro hard disk, MicroDrive), mostly used in digital cameras (CF type II interface). 1.8 inches, mostly used in notebook computers and external hard disk boxes. 2.5 inches, mostly used in notebook computers and external hard disk boxes. 3.5 inches, mostly used in desktop computers, the external hard disk box with 3.5" hard disk needs an external power supply, which is inconvenient.

Later advancers use permanent memory to replace the hard disk drive. This kind of computer external storage device based on permanent memory, such as flash memory, is called Solid State Disk (Solid State Disk, Solid State Drive, SSD for short). Solid-state drives are made into the same shape as conventional hard drives, such as the common 1.8-inch, 2.5-inch or 3.5-inch specifications, and use a compatible interface to replace the aforementioned standard-sized hard disk drives (HDDs) in computers. . Although there is no rotatable disk structure in solid-state drives, this type of memory is still called a hard drive according to naming conventions.

Although solid-state drives (SSD) have the characteristics of low power consumption, no noise, anti-vibration, and low heat. These features not only allow data to be stored more securely, but also extend the continuous operation time of battery-powered devices. However, cost and service life are the biggest problems that limit the popularity of SSDs. At present, whether it is a permanent memory or a non-permanent memory, its cost per million bytes is much higher than that of a hard disk drive, and because Flash Memory has a certain write life, and the data will not be read after the life expires, Therefore, it has become another obstacle for the public to accept solid-state drives. Furthermore, it is difficult to repair the data of the solid-state hard disk after it is damaged. When the flash memory particles responsible for storing data are damaged, it is impossible for the current data repair technology to rescue the data from the damaged chip. On the other hand, traditional mechanical hard disk (HDD) may still Some data can be recovered.

In addition, the advantages and disadvantages of using a hard disk drive as an operating device and using a flash memory as an operating device are as follows:

The main advantage of using hard drives is the large memory capacity. According to the current product specifications of hard drives, 500GB and 640GB can already be mass-produced, and the memory capacity will be even larger in the future. Such a capacity is not enough for most users. is enough. However, compared to flash memory as a storage unit, hard disk drives have many disadvantages, including high power consumption, high temperature, and noise, etc., but the biggest fatal flaw is its stability. Spindle motor) generally has 5,400rpm (5,400 revolutions per minute) or 7,200rpm or even 10,000rpm. Under high-speed rotation of the hard disk drive, it is easy to be damaged by external collisions and vibrations. Once the magnetic track is damaged, it will be recorded on the magnetic track. It is easy to destroy all or part of the data on the computer, which has always been the biggest pain for computer users.

The main advantages of using flash memory are fast speed and no noise (because no motor is needed), but the disadvantages are that the capacity is too small and the cost is too high. Currently, the capacity of a single flash memory is about 8GB or 16GB. Therefore, 40 flash memories are required to achieve a capacity of 640GB. But if you only store the operating system and general applications, 16GB or 32GB is enough.

The reason is that, in view of the various problems of the known technology, in order to be able to solve them, the inventor based on many years of research and development in related fields and a lot of practical experience, thinking and improving ideas, using his personal professional knowledge and experience After many researches and special discussions, the storage device with multiple storage units and the control method thereof of the present invention have been successfully developed, which is indeed a creation with enhanced efficacy.

The backup parameter 1 is that the first solid state storage unit 131 and the second solid state storage unit 132 back up each other. , at this time the first storage unit 12 does not operate.

The backup parameter 2 is that the first storage unit 12 and the first solid-state storage unit 131 and the second solid-state storage unit 132 are mutually redundant. At this time, these three storage units are all actuated, and the multiplex control unit 14 compares the three For the file content of the storage unit, copy the latest file in any one of the storage units or the one with the same file name but the latest data date and time to the other two storage units.

Such a purpose can prevent the data from being restored immediately when any one of the storage units is damaged.

The multiplexing control unit 14 performs the following sub-steps according to the backup parameter 1:

(SP561) The power is turned on, and the multiplexing control unit 14 turns on the power of the second solid-state storage unit 132 (or the first solid-state storage unit 131 ) and executes SP562.

(SP562) Copy the file, copy the latest update file of the first solid state storage unit 131 (or the second solid state storage unit 132) to the second solid state storage unit 132 (or the first solid state storage unit 131) and execute SP563.

(SP563) Turn off the power supply, and turn off the power supply of the second solid state storage unit 132 (or the first solid state storage unit 131 ) after the copying is completed.

(SP564) Skip to (SP29) after rereading (reread) the synchronous update parameters (such as Table 1).

In addition, if the multiplexing control unit 14 performs the following sub-steps according to the backup parameter 2:

(SP561) The power is turned on, the multiplexing control unit 14 turns on the power of the first storage unit 12 and the second solid state storage unit 132 (or the first solid state storage unit 131 ) and then executes SP562.

(SP562) copy files, copy the latest update file of the first solid state storage unit 131 (or the second solid state storage unit 132) to the first storage unit 12 and the second solid state storage unit 132 (or the first solid state storage unit 131) Execute SP563.

(SP563) Turn off the power supply, and turn off the power supplies of the first storage unit 12 and the second solid-state storage unit 132 (or the first solid-state storage unit 131 ) after the copying is completed.

(SP564) Skip to (SP29) after rereading (reread) the synchronous update parameters (such as Table 1).

(SP29) judge whether to shut down.

In this step, the multiplexing control unit 14 judges whether the system terminal 20 chooses to shut down, if so, proceed to step SP30, if otherwise, it indicates that the system terminal 20 is still performing general operations, and returns to step SP550 to perform general operations and determine whether the time is up.

(SP30) shutdown.

The system terminal 20 shuts down the operating system, and then shuts down the storage device 10 .

The setting of the aforementioned two working modes can be realized in various ways, for example:

Before the storage device 10 leaves the factory, its working mode is preset.

Setting or changing the working mode by issuing commands from the system side, the setting of the working mode issued by the system side can usually be achieved in two ways, including in the basic input/output system (BIOS) or by executing an application program under the operating system (O.S.) .

In summary, the present invention has the following advantages:

In addition, at least one solid-state storage unit is provided in the storage device 10 having a first storage unit 12 as a preferred boot execution unit, and is mutually backed up and updated with the first storage unit 12 .

A solid-state storage unit (such as the first solid-state storage unit 131) is in the power-on state and serves as a boot execution unit, while the first storage unit 12 and other solid-state storage units (such as the second solid-state storage unit 132) are in the power-off state, In this way, not only can it achieve high-speed booting, power saving and low noise, but also because the power of other storage units is turned off, there will be no risk of poisoning or damage due to shock and impact.

There is a boot execution unit and at least one backup execution unit in a storage device 10. If the boot execution unit is damaged, it will be immediately switched to a backup execution unit to replace the boot execution unit, and the backup can be achieved without additional storage devices. Aid and alternate boot.
