A solid-state drive (SSD) is a media that uses flash modules so as to store data. The solid-state drives are still fairly new and more expensive than the classic hard disk drives (HDD), but they are considerably faster, so they are frequently used for Operating Systems and apps on both home PCs and servers. An SSD is recommended as it doesn't have spinning disks which limit its speed and could cause overheating like it could happen with an HDD. Most companies work with SSDs for caching purposes, so all the content that is accessed more frequently will be held on this kind of drives, while all the other content will be stored on regular HDDs. The reason to use this kind of a setup is to balance the cost and performance of their Internet hosting platform and to reduce the load on the HDDs resulting from numerous reading and writing processes.
SSD with Data Caching in Web Hosting
The cloud platform where we create web hosting accounts uses only SSD drives, so your web applications and static sites will open extremely fast. The SSDs are used for files, e-mail addresses and databases, so no matter if you load a page or check for new e-mails with webmail, the content will load immediately. In order to offer even higher speeds, we also use a number 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 later on read from them and not from the primary storage drives. Needless to say, that content is replaced dynamically for improved performance. What we achieve that way except for the better speed is decreased overall load, thus reduced probability of hardware failures, and longer lifespan of the main drives, which is one more level of protection for any information that you upload to your account.
SSD with Data Caching in Semi-dedicated Servers
If you obtain one of our semi-dedicated server plans, your websites will be stored on a cloud platform which uses solely SSD drives for the storing of files, databases and email messages. In addition to the advanced ZFS file system that we use, this configuration provides fast loading speed for any web app hosted on our end. To guarantee that the sites of one customer will not affect the ones of another one, we also use multiple SSDs as cache - our system identifies files which are accessed more frequently and clones them, so they start loading from the caching drives. The content on the latter is refreshed dynamically and because of this we can balance the load on all the drives, warrant their long lifespan, decrease the risk of disk failures and, of course, provide a fast and reliable web hosting service.
