A solid-state drive is significantly quicker than any standard hard-disk drive. The reason is that a hard-disk drive employs rotating disks, which can rotate only so fast and the more info is read and written, the slower and warmer they get, whereas an SDD uses modules of flash memory, so there aren't any actually moving components. The access speeds for an SSD are significantly higher, which makes this kind of drives an ideal solution if speed is needed. This is the reason why SSDs are in many cases used for the Operating System on a PC and for keeping data that is accessed regularly on hosting servers. A lot of service providers also use a combination of both drives, so they save the data on hard-disks, but they use one or more SSDs so as to cache the more frequently used data and because of that, the data loads quicker while the load on the HDDs is decreased as their disks have to spin less often to read and write.

SSD with Data Caching in Shared Web Hosting

The cloud platform where we make shared web hosting accounts uses exclusively SSD drives, so your web applications and static websites will open extremely fast. The SSDs are used for files, emails and databases, so regardless of whether you open a page or check for new email messages using webmail, the content will load immediately. So as to ensure even higher speeds, we also use a group of dedicated SSDs which function only as cache. All of the content which generates lots of traffic is copied on them automatically and is afterwards read from them and not from the main storage drives. Needless to say, that content is replaced dynamically for better performance. What we achieve in this way except for the better speed is decreased overall load, thus reduced potential for hardware failures, and prolonged lifespan of the primary drives, which is one more level of security for any data that you upload to your account.
