A solid-state drive (SSD) is a media that uses flash modules so as to save data. The SSDs remain relatively new and more expensive when compared to standard hard disk drives (HDD), but they are faster, so they are quite often employed for Operating Systems and applications on both home PCs and servers. An SSD is preferred as it does not have spinning disks that restrict its speed and could cause overheating as it could happen with an HDD. Most companies employ SSDs for caching purposes, so all site content that is accessed more frequently will be stored on this kind of drives, while all other content will be stored on standard HDDs. The main reason to use this kind of a configuration is to balance the cost and overall performance of their web hosting platform and to decrease the load on the HDDs caused by countless reading and writing processes.
SSD with Data Caching in Website Hosting
The cloud platform where we create website hosting accounts uses only SSD drives, so your web apps and static websites will open extremely fast. The SSDs are used for files, e-mails and databases, so no matter if you open a page or check for new e-mails with webmail, the content will load immediately. So as to ensure even greater speeds, we also use multiple dedicated SSDs which function only as cache. All of the content that generates lots of traffic is copied on them automatically and is later on read from them and not from the main storage drives. Of course, that content is replaced dynamically for better efficiency. What we achieve in this way apart from the better speed is decreased overall load, thus decreased possibility of hardware failures, and longer lifespan of the primary drives, that is one more level of protection for any information that you upload to your account.
