NGFF-to-USB switching device and control circuit thereof for solid-state disk

Abstract

The present invention relates to an NGFF-to-USB switching device and a control circuit thereof for a solid-state disk. The NGFF-to-USB switching device comprises a USB interface, a PCB circuit board and a switching head, wherein the USB interface is welded at an edge of the PCB circuit board, the switching head is welded in the middle of the PCB circuit board, and the switching between the switching head and the USB interface is realized by virtue of a circuit on the PCB circuit board; and the switching head is an NGFF switching head. The control circuit of the NGFF-to-USB switching device for the solid-state disk comprises a master control chip control circuit, a USB interface, an NGFF interface, a high-current output power supply control circuit, upgrading firmware and a saved firmware control circuit. The NGFF-to-USB switching device and the control circuit thereof have the advantages of reasonable structural design, low manufacturing cost and small volume, a manufactured solid-state disk is small in volume and convenient to carry, the reading and writing speeds and the transmission speed are improved at the same time, and the problem of compatibility can be solved by using internal upgrading, so that the NGFF-to-USB switching device and the control circuit thereof are suitable for solid-state disks with different capacities.

Description

technical field [0001] The invention relates to the technical field of solid-state hard disks, in particular to an adapter device for converting NGFF to USB for solid-state hard disks and a control circuit thereof. Background technique [0002] The existing flash memory mobile storage devices include U disk, solid state hard disk, etc. With the continuous innovation of storage technology, the capacity and transmission speed of U disk and solid state hard disk have also been improved. For example, Netac’s U disk uses flash memory technology to achieve It can quickly read, write and transmit data, and provide convenience for people to use. However, the size of the U disk is fixed, the limitations are relatively large, and the read and write speed is relatively slow compared with the hard disk. [0003] Due to the large size of the traditional mechanical hard disk, it is inconvenient to carry, and the reading and writing is limited by the motor, which cannot meet the actual re...

AI Technical Summary

Problems solved by technology

However, the volume of the USB flash drive is fixed, and its limitations are relatively large. Compared with the hard disk, the read and write speed is relatively slow.

[0003] Due to the large size of the traditional mechanical hard disk, it is inconvenient to carry, and the reading and writing are limited by the motor, which cannot meet the actual needs of fast reading, writing and transmission, and high flexibility. Therefore, there is an urgent need for a new transfer method. Improve the performance of mobile hard drives to better meet people's needs
