Which brand of mobile hard disk should I buy?

For friends who buy mobile hard disks, reliability is the primary consideration, otherwise hard disks with more data loss will naturally merge. The mainstream mobile hard disk brands are mainly Western Digital, Hitachi, Toshiba and Seagate, and there is basically no big problem in identifying these brands at the beginning. Need to be reminded that since most mobile hard disks are designed as mechanical hard disks, you need to take measures to prevent earthquakes, and at the same time ensure that the transmitted data is normally powered on, and then move them after the hard disks completely stop working.

capacity

As far as mechanical keyboards are concerned, 500GB and 1TB should be the most common, and the price difference between them is not big, and 1T will be more cost-effective. As for the mobile hard disk of 2T or even larger, POPPUR is actually not recommended. After all, from the perspective of disaster backup, saving data separately is an effective way to ensure security. At this time, it may be more reliable to choose multiple hard disks for mutual backup. If you are a professional in video, photography, editing, etc. , or choose a large-capacity hard disk (special consideration in special circumstances).

Engagement/interface

The interface specification of mobile hard disk largely determines the transmission speed. At present, mainstream mobile hard disks support USB3.0 specification (blue plastic column), and the backup speed will be one grade faster than USB2.0 and other specifications (provided that your computer also supports USB3.0 specification), so there is no suspense in choosing USB3.0. In contrast, you don't have to consider too much speed.

measure

Mobile hard disks are divided into 3.5-inch and 2.5-inch sizes, which are the traditional standards for notebook hard disks and desktop notebooks respectively. 2.5-inch mobile hard disk is generally composed of notebook hard disk and hard disk box, which requires very little driving power and can be directly used by plugging it into the USB interface of the computer. The 3.5-inch hard disk needs a large driving bell, and an external power supply is needed in addition to the USB data cable. Although the portable requirement of mobile hard disk is not high, 2.5 inches is more suitable for the current use rhythm.
