A solid-state drive (SSD) is a media which uses flash modules in order to store information. The SSDs are still fairly new and more pricey when compared to classic hard disk drives (HDD), however they're faster, so they are ordinarily employed for Operating Systems and applications on both PCs and web hosting servers. An SSD is preferred as it doesn't have spinning disks which limit its speed and can cause overheating as it may happen with an HDD. A lot of companies use SSDs for caching purposes, so all site content which is accessed more frequently will be stored on this kind of drives, while all the other content will be stored on standard HDDs. The reason to use such a configuration is to balance the cost and performance of their website hosting platform and to decrease the load on the HDDs caused by numerous reading and writing processes.
SSD with Data Caching in Shared Web Hosting
The cloud platform where we make shared web hosting accounts uses solely SSD drives, so your web applications and static websites will load very quickly. The SSDs are used for files, e-mails and databases, so regardless of whether you load a page or check for new email messages through webmail, the content will load immediately. In order to ensure even higher speeds, we also use multiple dedicated SSDs that function only as cache. Any content which generates lots 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 better efficiency. What we achieve this way in addition to the better speed is lowered overall load, thus reduced chance of hardware failures, and longer lifespan of the primary drives, which is one more level of protection for any data that you upload to your account.
