A solid-state drive is really quicker than any normal hard disk. The reason is that a hard-disk drive works by using spinning disks, that can rotate only so fast and the more information is read and written, the sluggish and hotter they become, while an SDD employs modules of flash memory, therefore there aren't any physically moving components. The access speeds for an SSD are a lot higher, which makes these drives the right solution in case speed is needed. Because of this SSDs are frequently employed for the Operating System on a computer system and for keeping data which is used frequently on web servers. Many providers also use a combination of both drives, so they store the data on hard disk drives, but they use one or more SSDs in order to cache the more often used data and as a result, the data loads a lot quicker while the load on the HDDs is decreased as their disks have to spin less often in order to read and write.
