A solid-state drive (SSD) is a media which uses flash modules in order to save information. The SSDs remain relatively new and more expensive than the standard hard disk drives (HDD), but they are much faster, so they are quite often employed for Operating Systems and applications on both PCs and hosting servers. An SSD is preferred because it does not have spinning disks which limit its speed and could cause overheating as it may happen with an HDD. Lots of companies work with SSDs for caching purposes, so all site content which is accessed more often will be located on this kind of drives, while all the other content will be stored on regular HDDs. The 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 numerous reading and writing processes.

SSD with Data Caching in Shared Hosting

The cloud platform where we make shared hosting accounts uses only SSD drives, so your web apps and static sites will load very fast. The SSDs are used for files, email addresses and databases, so regardless if you load a page or check for new e-mail messages through webmail, the content will load right away. So as to ensure even greater speeds, we also use a group of dedicated SSDs that work only as cache. All of the content which 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 improved efficiency. What we achieve in this way in addition to the better speed is lowered overall load, thus decreased possibility of hardware failures, and longer lifespan of the primary drives, that is one more level of protection for any data that you upload to your account.

SSD with Data Caching in Semi-dedicated Hosting

All semi-dedicated hosting accounts that we provide are generated on a cloud platform that employs solely SSD drives. We do not use HDDs any longer, so your Internet sites will load very quickly since we use SSDs for every aspect of the service - files, databases and e-mails. Considering that some users may host Internet sites that can be more popular than others, we also use a number of drives for caching. Our system detects all of the content that is loaded more regularly and duplicates it on these drives so as to load it from them. This configuration is used for load-balancing purposes as we make sure that several reading/writing intensive sites will not affect the performance of the rest of the websites which are stored on the very same primary drive. Using caching drives also increases the lifespan of the main storage SSDs and reduces the chance of disk failures.
