Advantages of SSD over HDD Updated: 08/31/2020 by Computer Hope

The standard HDD (hard disk drive) has been the predominant storage device for computers (both desktops and laptops) for a long time. The main draw is the high storage capacity and low cost.

The SSD (solid-state drive) is another storage solution and is slowly replacing the majority of hard disk drives. As you'll learn by reading the following comparison table, the SSD is a clear winner. However, due to its price per unit of memory, it doesn't make sense to use SSDs in all instances. For most computer users, we recommend using an SSD as the primary drive for your operating system, and the programs you access most frequently. Then, we suggest purchasing a large HDD (either internal or external) for storing documents, pictures, and music.
