All computer data is stored on a computer hard drive. The Hard Disk Drive (or HDD), is the secondary computer storage device, and the Random Access Memory or RAM is the primary. Any data on the RAM is volatile and will be lost if the computer shuts down.

An explanation on Hard Drives

Installing or purchasing the correct hard drive is vital towards a desktop or laptop as it allows you store information on them. This information is stored on circular platters on the HDD.

On a hard drive, data is stored on circular platters. When a hard drive case is opened, the platters get contaminated by air and it won’t work again. The actuator arms run between the platters reading the information in 1’s and 0’s. The head of the arm reads data even when the disk is running at 7200 rpms (a common hard drive speed). These days, computer hard drives can do up to 15,000 rpms. The head reads it and processes the information which then proceeds to the connector which connects to the computer.

External or Internal?

Internal hard drives are tricky to remove from your desktop however you can purchase external hard drives to store information that is portable and easily accessible.
External drives are useful for backing up your computer and for transferring files. These drives are also portable.

Hard Drive Capacity

Hard drives are measured in Gigabytes (GB) and computers vary in their storage sizes depending on the type of hard drive the desktop/laptop has. These can vary between 60GB to 2TB+. Hard drive capacities vary between 1GB (or lesser) to 2TB (maybe even bigger).
