Description

Hard disk device capable of improving execution efficiency and reading and writing method thereof

The present invention relates to a hard disk device, and more particularly to a hard disk device capable of improving execution efficiency, and the controller of the hard disk device can use a RAID 0 (Redundant Array of Independent isks, RAID, redundant array) technology. Divide the data of a program specified by the computer (such as boot data, drawing program, paperwork program, etc.) into several sections and write them to a conventional hard disk drive (HDD) and a solid state drive. In Solid State Drive (SSD), when reading the data of the program, the program data is read from each of the hard disks, thereby improving the execution efficiency of the program.

Generally speaking, when the user turns on a computer, the computer performs a booting process to read a booting data stored in one of the hard disks connected thereto, so that the operating system of the computer can be completed according to the booting data. With each initialization setting, the computer can successfully execute the operating system and complete the entire booting process. When the user shuts down the computer, the computer also needs to operate the operating system during the operation of the operating system. The changed settings are written into the hard disk, so that when the user turns on the computer next time, the same operating system setting data as when the previous shutdown is performed can be obtained. Therefore, according to the foregoing, the computer is turned on (or Shutdown) The main factor of efficiency is the read and write speed of the bootable hard disk on the computer.

In recent years, there are two types of hard drives that are popular in the market:

A conventional hard disk drive (HDD) includes a magnetic read/write head and at least one magnetic disk, wherein the magnetic read/write head is disposed adjacent to each of the magnetic disks, and each of the magnetic disks Each of the plurality of magnetic tracks is disposed on the chip. When the conventional hard disk performs the data read/write operation, each of the magnetic disks will be driven to rotate, so that the magnetic read/write head can sequentially write the data to each of the magnetic tracks. Searching for and reading data sequentially from each of the tracks; and

2. A solid state drive (SSD) includes a processing unit and at least one storage unit (DRAM or FLASH chip), wherein the processing unit is electrically connected to each of the storage units, so that the processing unit can The data is directly written into each of the storage units, or the data stored in each of the storage units is read.

Since the conventional hard disk is a mechanical structure, its volume and weight are inevitably large and heavy, and it is necessary to drive the mechanical structure of the magnetic head or the magnetic disk when performing data reading and writing operations. Therefore, it takes a lot of time and power to perform data reading and writing. However, the conventional hard disk does not have a limited number of writes as the storage unit of the solid state hard disk. Therefore, in general, the conventional The life of the hard disk is higher than that of the solid state hard disk; on the contrary, the solid state hard disk is an electronic structure, and its volume and weight are obviously smaller and lighter than conventional hard disks, and when performing data reading and writing operations, only Through the electronic structure of the processing unit or the storage unit, the time and power required to perform the data reading and writing operation is much lower than that of the conventional hard disk. However, the fly in the ointment is the storage unit of the solid state hard disk. The service life is inversely proportional to the number of times it is executed. Therefore, there are only a limited number of writes, and the price of a solid-state hard disk of the same storage capacity is much higher than that of a conventional hard disk.

According to the above, the conventional hard disk is obviously more economical than the solid state hard disk and has a long service life, so it is still selected by the industry as a bootable hard disk on various computers. However, since the conventional hard disk is in progress When reading and writing data, it is necessary to drive each of the magnetic discs and the magnetic head, and the data can be read and written smoothly. Therefore, it takes a very long time for various computers to execute the booting or shutdown programs. Even to the extent that the user mistakenly think that the computer is malfunctioning. Therefore, if you want to effectively improve the efficiency of turning the computer on or off, the industry seems to be able to choose only SSDs with high read/write speed. At present, the solutions used by the operators can be divided into the following two types:

(A) Developed a new hybrid hard drive (Hybrid Hard Drive), such as the hybrid hard drive designed by Microsoft and Hard Disk Drive for Windows Vista operating system. The hybrid hard drive is built-in. NAND flash memory (a type of solid state hard disk) is on a conventional hard disk board. The portion of the conventional hard disk that is cheaper and cheaper uses a larger storage capacity for storage. General data, and the more expensive part of the NAND flash memory, uses a smaller storage capacity, which is only used to store the boot data required by the Windows Vista operating system when the computer is turned on, thereby avoiding a single Large-capacity NAND flash memory, resulting in a significant increase in cost and causing consumers to bear the high cost of the NAND flash memory; and

(B) Adopting a concept similar to the hybrid hard disk, such as Intel's Robson series computer, the NAND flash memory is designed on a computer motherboard equipped with a Robson chipset, and its storage capacity is only for storing the computer. When booting data required by the Windows Vista operating system, the regular hard disk is connected to the computer and uses a large storage capacity for storing general data.

However, regardless of the above scheme, the boot data is completely stored in a solid state hard disk (such as NAND flash memory). Since the solid state hard disk has only a limited number of writes, it is hard in the solid state. After using the disc for a period of time, it is very likely that in the state without warning, the damage will occur due to the number of writes that have expired, resulting in the risk of data corruption. Moreover, in general, the computer must not only be turned on or off. Reading and writing the boot data stored in the solid state hard disk. During the user's operation of the computer, the computer may read and write the solid state hard disk for various execution programs at any time. The boot data is completely stored in the solid state hard disk. It is foreseeable that the solid state hard disk must perform a large number of writing operations, so that the life of the solid state hard disk is shortened, and the user often causes the solid state hard. If the disc is damaged, the boot disk or computer must be re-purchased or repaired, and the boot data must be reinstalled and set. Therefore, the above solution will still cause the user to Spend the inconvenience and distress.

Therefore, how to design a hard disk device capable of improving the execution efficiency and a reading and writing method thereof, so that the user can effectively improve the efficiency and prevent the cause of the computer when the computer is turned on and off by using the hard disk device. The hard disk is damaged, and the risk and trouble of the boot data corruption occur, effectively ensuring the integrity and security of the boot data, which has become an important issue for the hard disk related industry to study and hope to solve.

In view of the many problems and shortcomings in the above-mentioned methods for improving the efficiency of execution, the inventors have finally developed and designed a "hard disk device capable of improving the execution efficiency according to the present invention based on years of practical experience and research experiments.
