A solid-state drive (SSD) is a media which uses flash modules so as to store info. The solid-state drives are still relatively new and more expensive compared to classic hard disk drives (HDD), but they are much faster, so they are often used for Operating Systems and applications on both personal computers and web servers. An SSD is preferred because it does not have spinning disks which restrict its speed and may even cause overheating as it may happen with an HDD. Many companies employ SSDs for caching purposes, so all website content which is accessed more often will be kept on this kind of drives, while all the other content will be stored on standard HDDs. The main reason to use this type of a configuration is to balance the price and overall performance of their web hosting platform and to lower the load on the HDDs resulting from countless reading and writing processes.

SSD with Data Caching in Hosting

The cloud platform where we create hosting accounts uses solely SSD drives, so your web applications and static sites will load very quickly. The SSDs are used for files, e-mail addresses and databases, so regardless if you open a page or check for new email messages with webmail, the content will load without delay. So as to ensure even higher speeds, we also use a group of dedicated SSDs that function only as cache. All of the content that generates a lot of traffic is copied on them automatically and is afterwards read from them and not from the primary storage drives. Of course, that content is replaced dynamically for much better efficiency. What we achieve that way except for the better speed is reduced overall load, thus lower potential for 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 Servers

All semi-dedicated server accounts that we provide are made on a cloud platform that uses only SSD drives. We don't use HDDs anymore, so your Internet sites will load very fast since we employ SSDs for each aspect of the service - files, databases and e-mails. Considering that some customers may host sites that are more popular than others, we also use many drives for caching. Our system finds any content that is loaded more regularly and clones it on these drives so as to load it from them. This setup is used for load-balancing purposes as we make sure that several reading/writing intensive websites will not affect the performance of the rest of the websites that are stored on the same main drive. Using caching drives also increases the life-span of the main storage SSDs and reduces the chance of disk failures.
