A solid-state drive is incredibly quicker than any conventional hard disk. It is because a hard-disk drive uses spinning disks, that can rotate only so fast and the more information is read and written, the sluggish and hotter they get, whereas an SDD takes advantage of modules of flash memory, hence there aren't any actually moving components. The access speeds for an SSD are substantially higher, which makes this type of drives the best solution if speed is needed. Because of this SSDs are often employed for the Operating System on a computer system and for keeping data which is accessed repeatedly on web servers. A large number of providers also use a combination of both drives, so they keep the data on HDDs, but they use several solid-state drives in order to cache the more frequently used data and because of that, the data loads faster while the load on the HDDs is lowered because their disks need to spin less frequently to read and write.
SSD with Data Caching in Web Hosting
The cloud platform where we create web hosting accounts uses solely SSD drives, so your web apps and static sites will load extremely fast. The SSDs are used for files, email addresses and databases, so no matter if you open a page or check for new e-mails through webmail, the content will load very quickly. In order to ensure even better speeds, we also use a number of dedicated SSDs that work only as cache. All content which generates lots of traffic is copied on them automatically and is afterwards read from them and not from the main storage drives. Of course, that content is replaced dynamically for improved efficiency. What we achieve in this way apart from the better speed is lowered overall load, thus reduced potential for hardware failures, and extended lifespan of the main drives, that's one more level of security for any data that you upload to your account.
