Introduction to external storage drives
The installation of an external drive is simple – just plug it into a USB or eSATA socket. USB devices can be plugged into a computer and unplugged while it is switched on safely. However, note that Windows does support SATA or eSATA (external SATA) hot-plugging but does not support hot unplugging, so switch the computer off before disconnecting an SATA or eSATA drive.
The main use of external hard disk and SSD drives – external and portable SSDs are now available – and Network Attached Storage (NAS) devices, is to store files and folders and to contain backups and whole system images that can be restored should something disastrous happen to the computer from which they were created. A NAS device provides more than storage and can be used as a home file server. Click on link 7 under Contents above for more information on them. You can make use of an old computer and the free operating system called FreeNAS to create a home file server on a home network.
External hard disk drives that have very large data-storage capacities are available for under £50, so there is no excuse for not having one and for not creating regular or scheduled backups. External SSDs were about four times as expensive as external HDDs in July 2015.
Here is the information on backups and system images on this website:

External USB storage drives as shown in the Windows Device Manager
The image below shows the disk drives listing in the Device Manager in Windows 10 for three storage drives. The first drive is an internal Crucial SSD, the second is an external USB Seagate drive and the third is also an external USB drive, the manufacturer of which is not shown because it is using Windows generic device drivers, not its manufacturer’s drivers. Note that generic drivers can cause a failed connection problem because the drivers can’t get through the USB sub-system.
