A solid-state drive (SSD) boosts the performance of each application running on it compared with a common hard-disk drive (HDD). The reason is that a solid-state drive uses many different interconnected flash memory modules, so there are no physical parts to move. In comparison, a hard disk employs spinning disks and each reading or writing process causes the disks to move, meaning the speed of an HDD is fixed. As the prices of the two types of drives are also different, many computer systems and web servers are equipped with an SSD for the operating system and various applications, and a hard disk for file storage, thus balancing cost and efficiency. A web hosting service provider could also use a solid-state drive for caching purposes, thus files that are accessed repeatedly will be held on this type of a drive for accomplishing improved loading speeds and for reducing the reading/writing processes on the hard-disk drives.
