Hard Disk Drive (HDD)

A hard drive or hard disk drive (HDD) is a type of data storage device that is used in laptops and desktop computers. An HDD is a “non-volatile” storage drive, which means it can retain the stored data even when no power is supplied to the device.

An internal or an external hard drive is a permanent storage device where you entrust the safety of all your data to. Thus, it is important that your hard drive displays the level of reliability you want it to have.

Finding the right one, however, can be a chore as there are loads of hard drive brands out there with varying specifications and capacities.

HDD is their significantly larger capacities. You can get HDD with capacities up to 20TB right now, and while these can be pretty expensive, when you compare their price per gigabyte of capacity, they are an incredible value.

Solid State Drive (SSD)

An SSD, or solid-state drive, is a type of storage device used in computers. This non-volatile storage media stores persistent data on solid-state flash memory. SSDs replace traditional hard disk drives (HDDs) in computers and perform the same basic functions as a hard drive. But SSDs are significantly faster in comparison. With an SSD, the device’s operating system will boot up more rapidly, programs will load quicker and files can be saved faster.

SSDs are used anywhere that hard drives can be deployed. In consumer products, for example, they are used in personal computers (PCs), laptops, computer games, digital cameras, digital music players, smartphones, tablets and thumb drives. They are also incorporated with graphics cards. However, they are more expensive than traditional HDDs.

Both SSDs and RAM incorporate solid-state chips, but the two memory types function differently within a computer system.
