How big is the mobile hard disk enough?

It depends on how you use it. If you like watching movies and want to save high-definition movies, you'd better choose a slightly larger one, 1TB or 2TB. If you just want to save some files or something, 500G is definitely enough. The 2TB Toshiba Alumy mobile hard drive I bought is said to store 240 HD movies, 400,000 photos and 500,000 songs, which is very suitable for people like me who usually like watching movies.

Mobile hard disk, as its name implies, is a storage product that uses hard disk as storage medium, exchanges large-capacity data between computers and emphasizes portability.

The vast majority of mobile hard disks in the market are based on standard hard disks, and only a few are micro hard disks (1.8 inch hard disks, etc. ), but the price factor determines whether the mainstream mobile hard disk is based on the standard notebook hard disk.

Because the hard disk is used as the storage medium, the data reading and writing method of the mobile hard disk is the same as that of the standard IDE hard disk. Mobile hard disks mostly use faster transmission interfaces such as USB, IEEE 1394, which can transmit data with the system at a higher speed. As of 20 15, the reading speed of mainstream 2.5-inch brand mobile hard disk is about 50-1000 MB/s, and the writing speed is about 30-80 MB/s. ..
