Description of the Invention: [Technical Field] The present invention relates to a method for accelerating data access, which is applied to an access device and a computer, the access device and the computer, a conventional hard disk respectively Connected to a memory hard disk (such as a solid state hard disk). After executing the operating system, the computer establishes an index table according to a control program, and the access device determines the value from the flag in the index table. The conventional hard disk reads data from the memory hard disk and transmits the data to the computer to accelerate the data access. [Prior Art] Press, Solid State Disk (Solid State Drive, SSD) is a computer data storage device based on permanent memory (such as flash memory). The rotating disk mechanism visible in the conventional Hard Disk Drive (HDD) is no longer present in the solid state disk. However, since the solid state disk is often used to replace the conventional hard disk, it is applied in action. In electronic devices (such as pen-type computers), the industry refers to Ssd as a solid-state hard disk according to past naming conventions, and it is often regarded as a kind of hard disk in the sales channel. Since the solid state hard disk is not a (10) read/write head for reading and writing rotating discs, the disc has traditionally been a hard disk technology. (4) The technology of the hard disk society is to connect several domain bodies (such as NAND memory), and then match the appropriate control chip and circuit to form a storage device. In terms of solid-state hard disk specifications, since solid-state hard disks are often used as replacements for conventional conventional hard disks, most manufacturers will set the solid-state hard disk to the same specifications as conventional hard disks, such as the common 18 Inches, 2.5 inches or 201142587 3.5 inches. In terms of the connection interface between the SSD and the computer, the current solid-state hard disk generally uses the SATA2 interface, but some solid-state hard disks also use IDE, SATA, SATA3, 1394, USB, or PCI-E interface. In addition, the memory used in solid-state hard disks can be roughly divided into two categories: MLC (Multi_Level, multi-layer storage) and SLC (Single-Level Cell), and the newer ones are TLC. (Triple-Level Cell) memory, which allows for fewer erases and fewer lifetimes. As far as the current technology is concerned, the use of solid-state hard disk with both c is lower than that of using SLC, but the writing speed is lower and the service life is shorter. Lu Zheng is a solid-state hard disk that does not need to be driven by a motor to drive the disc. Therefore, the solid-state hard disk has noiselessness, low power consumption, high shock resistance during reading and writing, low heat generation and light weight, etc. compared with conventional hard disk. Advantages, this also makes the solid state hard disk very suitable for application on mobile electronic devices. In addition, according to the relevant test data, the reading speed of the solid state hard disk can be about 2 to 3 times higher than that of the conventional hard disk. The speed can also be more than 1.5 times that of a conventional hard disk. In the current situation where conventional hard drives become system performance bottlenecks, the use of solid state drives should be a good solution. However, although the solid state hard disk has excellent performance in terms of access speed and some physical characteristics, there are still many shortcomings to be improved. In terms of price, currently, whether it is permanent memory or non-permanent. § 忆 体 ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' ' Hard disk replaces conventional hard disk, not only that, but more importantly, 'because the memory in the solid state disk is not directly written when writing data, 'but the original data is erased' to write new data. The physical limitation causes the memory in the solid state hard disk to have a certain number of write times, and the more the write, the slower the continuous write speed. The above shortcomings mean the use of solid state hard drives 201142587 The fate is often lower than the regular (four). If the maker (4) hard disk completely replaces the conventional hard disk on the personal computer, then the solid-state hard disk must bear a lot of writing work, and this will cause the hard surface to be quickly broken, and the solid hard must be assumed. The risk of damage to the disc at any time is quite unsatisfactory. Not only that, but if the hard disk is damaged, not only may the data be lost, but the user must re-purchase the new hard disk, causing the user to bear extra money. At present, some manufacturers have developed a hybrid storage device (Hybrid's technology is generally called face-to-face, mainly installed on a computer-control device and connects the conventional hard disk and _solid|| to the control weaving, The principle of acceleration is to combine the above-mentioned conventional hard disk and solid state hard disk into a RAID 1 device, so that the computer can output data from the hard disk drive through the control device, and the computer can simultaneously write the two hard disks through the control device. Although the technology can barely increase the reading speed of the data, when the data is written, the control device will simultaneously write the writer to the conventional hard disk and the solid state hard disk. In this way, the solid-state hard disk must still bear frequent writes, which greatly degrades the service life of the hard disk. It is not ideal. In addition, some manufacturers have improved the above HD_〇ST technology, and its content is mainly Is to use the control device to find the f-regulation (four) stand-by-week, so that the weaving of the contents of the look-up table 'read solid-state hard disk or conventional hard disk data, or according to the inner valley of the comparison table' will be conventional Hard disk data copied to solid state hard Dishes: However, when the control device establishes a dragon watch in a conventional hard needle, the county (4) industry is directly, but several Weizhongs of the conventional hard disk are established in the county, and thus, the magnetic regions are originally stored. The data of the job is destroyed, and may even make part of the system (4)

In this way, it can be used, not only quite time-consuming and laborious, but also a large number of operations that can be performed by ordinary users. Therefore, how to improve the above-mentioned problems, in the premise of not writing human solid-state hard disk many times, 'utilizing the characteristics of fast reading speed of hard disk, and improving the speed of computer accessing hard disk data, is the invention for this purpose. An important topic. [Invention] In view of the many problems mentioned above, the inventors have finally developed and designed the method of accelerating data access of the present invention through long-term efforts and experiments, and read speed by means of a memory hard disk (solid state hard disk). Fast features, speed up the speed of computer access to hard disk data, and make the memory "(solid-state hard disk) money overwhelming writer Wang Zuo, to the long life of solid-state hard disk. It is an object of the present invention to provide a method for accelerating data access, which is applied to an access device and a computer, which is difficult for the computer, a conventional hard disk (Hard Disk Drive, _ for short) A memory hard disk (such as a solid-state drive (SSD)) is connected, wherein the memory hard disk has a higher reading speed than the conventional hard disk, and the conventional hard disk includes a normal area. The normal system stores an operating system (〇peratingSystem, 〇s), and the operating system is equipped with a - (four) program, the constant _ is divided into a plurality of financial rules section, and 201142587 the memory supplement is divided into plants a mirror segment, each of which corresponds to each of the regular segments; after the computer executes the system, it will establish a table in the conventional hard shot according to the requirements of the control program, the index table Including a plurality of side positions, each fine position, private-simplified, and each paste position corresponding to each of the regular sections respectively, when the flag of the barrier (four) is - the first value (such as; "〇"), Representing the regular section of the column (4), the Wei (4) section The same content, and the other, when the flag bits within the block is a second value (eg; Gamma] 1 ") when the field corresponding to the representative of the regular segment, and storing the content of the red segment mirror (iv) different phases. When the computer reads the data, the access device reads the corresponding interceptor in the index table, when the flag of the read field is the first value (that is, the corresponding normal area) The segment is matched with the data of the lining in the mirror, and the scale device selects to read the data stored in the corresponding mirror segment (higher reading speed) and transmits it to the computer' or in the access When the device reads that the block is the second value (that is, the corresponding regular segment is different from the data stored in the mirror segment), the access device selects to read the corresponding value. The data stored in the regular section (slower reading speed) is transferred to the computer. Thus, when the computer reads the data through the access device, that is, the monthly b reads part or all of the data from the faster hard disk of the memory, thereby greatly increasing the reading speed of the data. Another object of the present invention is that when the computer wants to write data to the conventional hard disk, the access device first receives a write command from the computer, and accordingly the conventional hard disk After performing the write operation, after completing the write operation, and changing the data stored in the regular section, the access device will flag the field corresponding to the regular section according to the reference table. The flag is set to the second value. In this way, the access device only writes the data to the conventional hard disk first, thereby reducing the number of times the memory hard disk is '201142587' and increasing the lifetime of the memory hard disk. A further object of the present invention is to enable the access device to receive a drive command from the computer (eg, to perform a four-way drive command), or when the user presses a button on the access device, The access device reads each of the blocks in the index table according to the index table, and when the flag of the read block is the second value, the access device will correspond to the field. The data stored in the regular section is copied to the mirror segment corresponding to the block, and the flag of the block is changed to the first value to complete the corresponding segment and the mirror Mirroring between sections. Thereby, not only can the number of times of writing the hard disk of the memory be reduced, but also the data of the regular segment and the mirror segment can be synchronized to increase the reading speed of the data. Not only that, the access device is placed in the process towel that executes the mirroring of the data, and is also connected to the (four) power_read command, and the data is transmitted to the computer in the above reading mode. In order to make the review committee able to make a more in-depth understanding and understanding of the purpose, structure and efficacy of the present invention, _ actual cooperation with the schema, the detailed description is as follows: [Embodiment] Press, Japanese industry commonly used "MemGry Disk ", as the memory device formed by the combination of memory and control chip", such as the number, (10) «touch, the purpose, the middle of the 2, called the battle hard disk" in other words, the case The "memory hard disk" is the memory device formed by the combination of the memory and the control crystal #.
