A solid-state drive is significantly quicker than any normal hard-disk drive. It is because a hard-disk drive works by using spinning disks, which can rotate only so fast and the more information is read and written, the slower and warmer they become, at the same time an SDD employs modules of flash memory, so there aren't any actually moving parts. The access speeds for an SSD are substantially higher, which makes these drives a preferred solution when speed is needed. Because of this SSDs are in many cases employed for the Operating System on a PC and for keeping data which is used repeatedly on hosting servers. A lot of providers also use a combination of both drives, so they keep the data on HDDs, but they use a couple of SSDs in order to cache the more frequently used data and for that reason, the data loads a lot quicker while the load on the HDDs is decreased since their disks have to spin less often to read and write.
SSD with Data Caching in Shared Hosting
The cloud platform where we create shared hosting accounts uses only SSD drives, so your web apps and static Internet sites will load extremely fast. The SSDs are used for files, emails and databases, so no matter if you open a page or check for new e-mails with webmail, the content will load very quickly. To ensure even higher speeds, we also use numerous dedicated SSDs which work only as cache. All of the content that generates a lot of traffic is copied on them automatically and is later read from them and not from the primary storage drives. Needless to say, that content is replaced dynamically for improved performance. What we achieve this way except for the improved speed is reduced overall load, thus reduced potential for hardware failures, and longer lifespan of the main drives, which is one more level of security for any info that you upload to your account.
