Therefore, how to preserve important documents and files is still a bottleneck in the development of computer systems.

In order to solve the requirement of preserving important documents and archives, various countermeasures have been put forward, that is, the Redundant Array of Inexpensive Disks (Redundant Array of Inexpensive Disks, referred to as Redundant Array of Inexpensive Disks, referred to RAID) is one of them.

Also, as mentioned above, disk arrays are divided into RAID 0, RAID1, RAID 2, RAID 3, RAID 4, and RAID 5 based on different management methods for storing and protecting important files and files. However, please refer to the figure 1, it is a device that completes data access and backup at different levels through a hard disk drive. An electronic device 200 is provided on the device, and the electronic device 200 corresponds to a disk array system 100 through a transmission line 211. The disk array system 100 is provided with a disk array controller 120, and the disk array controller 120 is connected with more than one set of hard drives 130, so that the electronic equipment 200 can be controlled through the disk array The device 120 controls the hard disk drive 130 to do data access and backup, but although the disk array system 100 can be used to store and back up a large amount of data, the hard disk drive 130 is used as the storage medium, and the hard drive itself is a mechanical device, so It will have the characteristics of mechanical damage and vibration, and it will also affect the execution speed because of the characteristics of using mechanical motor operation and using head movement to access when performing access and backing up a large amount of data, so Not ideal for use.

Contents of the invention

In order to solve the above-mentioned problems in the prior art, the purpose of this application is to provide a disk array device.

For realizing above-mentioned purpose of the present invention of the present invention, the present invention provides a kind of disk array device, mainly be provided with connecting interface, disk array controller and one or more flash memory by the disk array device and form; Electrical connection, through the connection interface, the present invention and the electronic equipment can transmit data between each other; wherein the disk array controller is electrically connected with the electronic equipment through the connection interface, and controls the storage and reading of data in the disk array device Wherein the flash memory is used as the storage and backup of data; when in use, by means of the above-mentioned device, the data is transmitted between the present invention and the electronic equipment, and the flash memory is used as the storage and backup of the data, so that the flash memory can It has the characteristics of quietness and high speed during storage, light, thin, short and easy to carry, which makes the storage and backup of data more perfect.

Detailed ways

In order to enable the examiners to have a deeper understanding and understanding of the present invention, the specific examples are provided in conjunction with the drawings, and the detailed description is as follows:

Please refer to shown in Fig. 2, the present invention is a disk array device, and this disk array device 10 can be implemented by an adapter card or other independent devices, and can be combined with electronic equipment 20; The disk array device has a connection interface 11, a disk array The controller 12 and more than one set of flash memory 13 are composed; the connection interface 11 is electrically connected with the electronic device 20, and the connection interface 11 can support different transmission protocols such as SATA, PATA, USB, IEEE1394, etc., so that when used, it can Through the connection between the connection interface 11 and the transmission line 111 , data is transmitted between the disk array device 10 and the electronic device 20 .

In addition, the disk array controller 12 can support flash memory 13 storage functions, such as: flash IDE disk (Flash IDEDisk), flash SATA disk (Flash SATA Disk), CF (Compact Flash) card, PCMCIA ATA card and other protocols. The disk array controller 12 is electrically connected to the electronic device 20 through the connection interface 11 to control data storage and reading in the disk array device 10 .

Furthermore, the disk array controller 12 is electrically connected to more than one set of flash memory 13, the flash memory 13 is used as data storage and backup, and the flash memory 13 is electrically connected to the disk array controller 12 through the conversion disk protocol interface 14. Sexual connection, wherein, the conversion disk protocol interface 14 converts the data output/input of the flash memory into the transmission protocol of the hard disk drive, such as agreements such as SATA, SCSI, and PATA.
