A solid-state drive (SSD) is a media that uses flash modules to store data. The solid-state drives are still relatively new and more pricey than the standard hard disk drives (HDD), yet they're faster, so they are often employed for Operating Systems and apps on both PCs and servers. An SSD is preferred as it doesn't have spinning disks which limit its speed and can even cause overheating as it may happen with an HDD. A number of companies work with SSDs for caching purposes, so all of the content that is accessed more often will be held on this kind of drives, while all other content will be held on conventional HDDs. The main reason to use such a configuration is to balance the price and performance of their hosting platform and to decrease the load on the HDDs resulting from numerous reading and writing processes.
SSD with Data Caching in Hosting
The cloud platform where we create hosting accounts uses exclusively SSD drives, so your web applications and static sites will open extremely fast. The SSDs are used for files, emails and databases, so regardless of whether you open a page or check for new emails using webmail, the content will load very quickly. In order to offer even better speeds, we also use numerous dedicated SSDs that function only as cache. Any 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 better efficiency. What we achieve that way except for the better speed is lowered overall load, thus decreased chance of hardware failures, and extended lifespan of the primary drives, which is one more level of protection for any data that you upload to your account.
SSD with Data Caching in Semi-dedicated Servers
If you obtain one of our semi-dedicated server packages, your websites will be stored on a cloud platform that employs exclusively SSD drives for the storing of files, databases and e-mail messages. Along with the advanced ZFS file system that we use, this setup guarantees very fast loading speed for each web application hosted on our end. To ensure that the Internet sites of one user won't affect the ones of another, we also use a number of SSDs as cache - our system detects files that are accessed more frequently and clones them, so that they start loading from the caching drives. The content on the latter is refreshed dynamically and for that reason we can balance the load on all the drives, guarantee their long lifespan, minimize the risk of disk failures and, of course, provide a super fast and reliable Internet hosting service.
