Description

Storage device with multiple storage units and control method thereof

The invention relates to a storage device with multiple storage units and a control method thereof, in particular to a storage device provided with at least two storage units, one of which is a solid storage unit.

Press, the personal computer is a Hard Disk Drive (HDD) as the loading device of the operating system, which uses a rigid rotating disc-based non-volatile storage device and is flat. The magnetic surface stores and retrieves digital data. The information is written to the disk by electromagnetic flow through a magnetic head that is close to the magnetic surface and is changed in polarity by electromagnetic flow. Information can be read back in the opposite way, such as a magnetic field causing a change in power in the coil or a head passing over it.

With the development of various electronic products, hard disk drives have developed various standard sizes for use in these electronic products, for example, 0.85 inches, which are mostly used in portable devices such as mobile phones. 1 inch (micro hard drive, 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 using 3.5" hard disk requires external power supply, which is inconvenient.

Later, there is a permanent memory instead of a hard disk drive. This external storage device based on permanent memory, such as flash memory, is called Solid State Disk (Solid State Disk, Solid State Drive, short for SSD). Solid-state hard drives are made in the same shape as conventional hard drives, such as the usual 1.8-inch, 2.5-inch or 3.5-inch sizes, and use a compatible interface to replace the aforementioned standard-size hard drive in a computer. (HDD). Although there is no disc-shaped disk structure that can be rotated in the solid state hard disk, according to the naming convention, such memory is still called a "hard disk."

Although solid state drives (SSDs) have low power consumption, no noise, vibration resistance, and low The characteristics of heat. These features not only make the data more secure, but also extend the continuous running time of battery-powered devices. However, cost and service life are the biggest problems limiting the popularity of solid state drives. At present, whether it is permanent memory or non-permanent memory, its composition per million is far higher than that of hard disk drives, and since Flash Memory has a certain write life, and the data will be read after the life span expires. Not coming out, it has become another obstacle for the public to accept solid state drives. In addition, the hard disk data is difficult to repair after the data is damaged. When the flash memory particles responsible for storing data are damaged, the current data repair technology is impossible to save the data in the damaged chip, and the traditional mechanical hard disk (HDD) ) Maybe still recover some data.

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

1. The main advantage of using a hard disk drive is that the memory capacity is large. In terms of the current product specifications of the hard disk drive, 500GB and 640GB can be mass-produced and the memory capacity will be larger in the future. It is sufficient for the user. However, compared to flash memory as a storage unit, hard disk drives have many shortcomings, including large power consumption, high temperature and noise, etc., but the biggest fatal flaw is its stability, two and a half hard disk drives. The Spindle motor generally has 5,400 rpm (5,400 laps per minute) or 7,200 rpm or even 10,000 rpm. The hard disk drive is easily damaged by external impact and vibration at high speed. Once the track is damaged, The data recorded on the track is easily destroyed in whole or in part, which has been the biggest pain for computer users.

2. The use of flash memory, the main advantage is fast and no noise (because no motor), but the disadvantage is that the capacity is too small, and the cost is too high. At present, the capacity of a single flash memory is about 8GB or 16GB, so 40 flash memory is required to reach 640GB capacity. However, if only the operating system and general applications are stored, 16GB or 32GB is sufficient.

The reason is that in view of the problems of the prior art, in order to be able to solve the problem Inventors, based on years of research and development in related fields and many practical experiences, are thinking and improving ideas, poor personal expertise, and through multi-disciplinary research and topical discussions, have finally successfully developed this piece "with multiple storage units."
