A solid-state drive (SSD) is a media that uses flash modules in order to store information. The SSDs are still fairly new and more pricey when compared to standard hard disk drives (HDD), but they're faster, so they are quite often used for Operating Systems and apps on both home PCs and web hosting servers. An SSD is recommended as it doesn't have spinning disks which limit its speed and may cause overheating as it may happen with an HDD. A large number of companies employ SSDs for caching purposes, so all website content that is accessed more often will be held on this type of drives, while all other content will be stored on conventional HDDs. The main reason to use such a setup is to balance the price and overall performance of their hosting platform and to reduce the load on the HDDs caused by numerous reading and writing processes.
SSD with Data Caching in Shared Hosting
The cloud platform where we make shared hosting accounts uses exclusively SSD drives, so your web apps and static sites will load extremely fast. The SSDs are used for files, e-mails and databases, so regardless if you open a page or check for new messages through webmail, the content will load right away. To ensure even higher speeds, we also use a group of dedicated SSDs which work only as cache. All of the content that generates a lot of traffic is copied on them automatically and is later on read from them and not from the primary storage drives. Needless to say, that content is replaced dynamically for much better efficiency. What we achieve this way aside from the better speed is decreased overall load, thus decreased probability of hardware failures, and extended lifespan of the primary drives, that is one more level of security for any info that you upload to your account.
SSD with Data Caching in Semi-dedicated Servers
In case you sign up for one of our semi-dedicated server plans, we'll hold your content on SSD drives and this is valid not only for the files, but also for all of the databases and e-mail messages. Thus, your script-driven applications and webmail will load very fast. We employ dedicated SSDs for caching as well. Traffic-intensive content is duplicated automatically on these drives, so we ensure that a couple of heavy sites that generate plenty of reading and writing processes won't affect the other websites that share the same drive. By reducing the overall load we also raise the lifespan of the primary storage drives and reduce the probability of a disk failure, so by using SSD drives for caching purposes, we add an extra level of protection for your site content.
