An external hard drive is designed to store and transfer large amounts of information that a flash drive cannot handle. This is the same hard drive (HDD) packed in a box with a power supply and controller. It is convenient to take it on the road to transfer information, it can be connected to a TV.
For larger volumes and at a lower price, you can purchase an HDD. Writing / reading is carried out by rotating the disk and the magnetic head. The vulnerability of such a drive is noise during operation, susceptibility to mechanical damage, low speed. If you need to transfer movies, music, text files, a compact, but more expensive SSD will do. This disk, like a flash drive, belongs to solid state drives.
The size and type of drive is called the form factor. The following types are distinguished: 1.8 "(up to 2 TB), 2.5" (up to 4 TB). The 3.5 ”drive (up to 8 TB) is a desktop option, since the large capacity implies both large dimensions and weight.

Product video review:
When choosing an external drive, you must focus primarily on the volume. Currently, the smallest is the 500 GB drive. What can be recorded on such a medium:
The most popular and affordable prices are 1 TB disks. This volume is quite enough to record two hundred FullHD movies.
Two terabytes - such a disk can be used for a complete copy of the system, movies of 4K UltraHD quality, about 50 pieces.
4TB drives for very large volumes, in most cases, they are stationary, designed for professionals.
When choosing an external drive, the manufacturer is of no small importance, since reliability is the main indicator of a storage device. Appearance and durability are also relevant for some user group.
