When choosing, you should pay attention to the following aspects: 1. Choose according to the speed of the interface: Most of the mobile hard disks sold on the market currently use USB2.0 interfaces, and a small number of brands use USB3.0 interfaces. In terms of transmission speed, mobile hard disks with USB3.0 interfaces are about 10 times faster than those with 2.0 interfaces. Although the 3.0 interface is fast, it cannot fully support all models at present, and its popularity needs to be improved, but it represents the direction of future development. From the perspective of use, USB2.0 is currently more economical and practical, but speed is a bottleneck. 2. Choose based on the appearance of the mobile hard drive: Although the appearance of a mobile hard drive is not the main criterion for measuring quality, as a high-quality mobile hard drive, the fine workmanship can definitely reflect the reliability of the brand.

Regular manufacturers generally have a 2-year warranty on the hard disk, and some brands will also have a 3-year warranty. Only brands with good after-sales guarantee are worth choosing. 2How to identify the quality of mobile hard diskQuality identification of mobile hard disk: 1.
