Description

Portable Data Storage Device

technical field

The invention relates to a portable data storage device, in particular to a portable data storage device capable of direct data transmission with other portable data storage devices.

Background technique

Hard disk (hard disk) is a hardware device used by general computer systems to store data. Its advantage is that its capacity is larger than that of floppy disks, and it can store a considerable amount of data. The gigabyte (GB) used has the advantage of large capacity, which can be said to make the data processing required by the information more convenient.

And because of its relatively large volume, it needs to be installed in the host computer system in a fixed manner, so it is more suitable for storing databases and application software.

However, in order to meet the needs of convenient use, many users often need to carry out data, such as form data, or data transmission, etc., and they need to save the data in other data storage media first, so as to achieve the purpose of carrying out, such as Using floppy disks for data storage is the most common method.

However, due to the small capacity of the floppy disk (only 1.44MB), the data that can be stored is limited. If the data that the user wants to carry is an image or image file, the capacity of the general floppy disk is not enough. If the storage is achieved by data division alone, a piece of data may need to be stored in dozens of floppy disks.

Of course, there are also large-capacity and portable storage media, such as Zip disks (Zipdrive), which can provide large-capacity storage disks. However, they are not favored by users in use. The main reason is that It needs a Zip disk drive (Zip drive) to read and write the data of this type of disk. However, its hardware cost is high, so it is not very versatile in the market. Even if the user has such a device, other relatively However, there may not be many data users, so the versatility of use is quite limited.

In order to meet the needs of users, the flash drive was born accordingly. It mainly builds a certain capacity of memory in a main body, such as 16MB or 32MB, and sets a specific transmission interface to connect with the memory, so that when the memory is in use, That is, after inserting, it completes the information connection with the inserted electronic information device, and provides readable and writable data, making data transfer or carrying very convenient. Users can use the flash drive to store the attached Programs, back up important data, or to carry specific materials, such as animation files, presentation files, etc.

Please refer to shown in Fig. 1, it is a schematic structural diagram of a known flash drive 11 shown in the figure, and the flash drive 11 is built a memory 112 in a main body 111, and uses universal serial bus (universal serialbus, USB) as and The transmission interface that the computer carries out data transmission, shown in the figure is a USB port male plug 113; Universal Serial Bus supports plug-and-play and multiple data stream technologies, and can transmit at a bandwidth of 1.5 megabits per second (Mbps) data, therefore, the flash drive 11 becomes a portable portable data storage device, and the user can store frequently used data in the flash drive, and can be connected with any computer's USB port at any time to carry out data transmission.

However, the USB flash drive 11 must still carry out the data access action through the computer in the transfer of various data, for example: user A needs to upload the data of his flash drive A to a computer first, and then user B Insert the flash drive B into the USB port of the host computer to download the files stored in the flash drive A in the computer.

However, when the user is on a business trip or encounters some temporary situations, it is impossible to carry a notebook computer with him to carry out the mutual transmission and storage of data in two different flash drives. Therefore, the data cannot be stored immediately. Rapid transfer, which causes inconvenience to the user's operation.
