A solid-state drive (SSD) is a media that uses flash modules in order to save data. The solid-state drives are still relatively new and more pricey compared to standard hard disk drives (HDD), but they're faster, so they are ordinarily employed for Operating Systems and applications on both desktops and web servers. An SSD is preferred as it does not have spinning disks which restrict its speed and can cause overheating like it may happen with an HDD. A number of companies use SSDs for caching purposes, so all of the website content that is accessed more frequently will be kept on this kind of drives, while all the other content will be stored on conventional HDDs. The main reason to use this kind of a configuration is to balance the cost and performance of their website hosting platform and to minimize the load on the HDDs caused by intense reading and writing processes.
SSD with Data Caching in Website Hosting
The cloud platform where we create website hosting accounts uses solely SSD drives, so your web apps and static sites will open extremely fast. The SSDs are used for files, e-mail addresses and databases, so no matter if you open a page or check for new e-mails using webmail, the content will load very quickly. In order to offer even higher speeds, we also use numerous dedicated SSDs that work only as cache. All the content which generates a lot 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 much better performance. What we achieve by doing this except for the better speed is decreased overall load, thus decreased potential for hardware failures, and extended lifespan of the main drives, that is one more level of security for any data that you upload to your account.
