An external hard drive is an item that can be easily installed and transported from one device to another. It was created in 2009 and this device does not need to constantly consume electricity or battery. Previously these hard drives were a little more expensive, but since their sale with a lower value, the idea of having the same type of storage for backup copies has changed.
Long ago magnetic or magneto-optical discs were used but optical storage is used for definitive use while other media are used for interchangeable discs for support.
Hard drives that exist today can range from microdisks to full-size drives with custom enclosures. If we talk about the connections, the most used are USB 2.0, USB 3.0 and Firewire. There are also SCSIs and SATAs which, due to the length of the cable and their hot-plug capability, were possible to use in this way even though they were not created for external use.
The function of these devices is to store information quickly and easily in order to keep an automatic backup of files. Additionally, these disks allow file sharing between multiple computers. Currently these elements continue to have moving parts, for this reason it is advisable to use them carefully to avoid any failure due to a blow.
For use, USB microdive disks and laptops can be powered from the USB connection but in some cases the power they receive from it is not enough so they must be plugged into two USB drives at the same time so that there is a greater flow of power. stream. On the other hand, the use of a transformer is something of great importance for desktop, SCSI and ATA hard drives.
External hard drives can be of two types: solid state drives that have a more advanced and modern technology where information is stored on a board with transistors. These memories do not have external moving parts and this is the reason why they are more resistant, in addition they are also faster and quieter, but at a very high cost.
On the other hand, there are also magnetic units that record information on aluminum or glass discs through magnetic fields generated by a head, this is the one that allows data to be written while the disc rotates.
Another feature that we can mention about external hard drives is that they need a controller and a printed circuit to function properly. These elements allow you to convert the original format into Wifi, Firewire or USB. In some occasions, the capacities can be expanded and it can be recorded through a miniDV camera and the files are created directly.
There are also multimedia player hard drives, where it is possible to save videos and play them through an output that can be connected to the TV without adding any other device. However, we can also find hard drives that must be connected to other devices to function properly.
