Hard Drive Selection Guide

With the popularization of computers, the capacity of computer hard disks has begun to become more and more difficult. Therefore, more people have begun to choose mobile hard disks as an extension of computer hard disks, and it is also very convenient to carry and back up important data. So what should pay attention to buying a good mobile hard disk?

2. The speed of the hard disk is also an important aspect that we have to look at. If the transmission rate is too slow, it will not only affect the office efficiency, but also damage the battery of the computer and reduce the service life of the battery.

3. Security Since the mobile hard disk is a data storage device, the security of data should be guaranteed. Therefore, we must try to buy mobile hard disk with encryption technology. Then encryption technology is divided into software encryption and hardware encryption. The software encryption interface is complicated and easy to crack. Therefore, we have better choose a hardware-encrypted mobile hard disk and encrypt it with an electronic key to ensure data security.

4. Appearance and volume Since it is a mobile hard disk, of course, the main principle of light and easy to carry. The current mainstream market has 1.8-inch and 2.5-inch products of two sizes. Both are free to place, easy to carry, and the rest is to look at your own hobby.

5. After-sales service Since it is an electronic product, mobile hard disks are inevitably having a problem and are easily damaged. Therefore, it is recommended to buy a brand of mobile hard disk, because the brand manufacturers are deeply rooted in people's minds, generally have two to three years of after-sales service and technical support, trustworthy.
