SSD - Solid-state drive

What is an SSD?

SSD stands for (solid state drive). It's a faster and more reliable method of storing digital data on a computer. For decades, computers have stored information on hard disk drives (HDD). Traditional HDDs are significantly cheaper in comparison to the equivalent SSD so they still have a place in the market.

What is the benefit of using SSD?

Traditional hard disk drives contain many moving parts including a motor that needs to rotate between 5400 and 7200rpm. The HDD's motor needs to reach its operating speed before data can be accessed. This produces a delay in reading and writing data to the disk. The only way to avoid this delay is to switch off the HDD energy-saving features, which will increase power consumption and reduce the lifespan of the drive. An SSD uses flash memory which means data is stored on microchips, avoiding the need for any moving parts. Without the need for mechanical components, SSDs can operate more efficiently, saving power and resulting in a more durable component.
