However, you can opt for another more compact, manageable, and sophisticated kind of hard drive: the solid-state drive (SSD). In terms of size and design, they are the biggest type available on the market. The models that operate in the way we just explained are called hard disk drives (HDD). What are the types of external hard drives?
What this means is that both the file writing and the reading of those already written occurs simultaneously. The rotation of the axis on the disks causes the movement of each of the needles with a reading and writing head sliding on the disks. This axis rotates at high speed inside a metal case. To speak in general terms, they consist of one or more hard drives that are covered by a magnetic material and joined by an axis. Their mechanical operation is very similar to that of conventional hard disks, so we can explain how these storage devices work in general. That way, you can recycle your old computer’s hard disk. These often come with a protective casing and are used as external hard drives using a USB connection. The main difference with conventional models is that you can physically transport them and connect them to a variety of other devices.Ĭertain types of hard drives that are integrated into electronic devices but can be removed are also considered to be external disks. What is an external hard drive and how does it work?ĭespite being a piece of hardware in its own right, this portable hard drive isn’t integrated into the internal structure of the computer, tablet, or any other device to which it provides storage.
