A solid-state drive (SSD) is a media which uses flash modules in order to save information. The solid-state drives are still fairly new and more pricey when compared to standard hard disk drives (HDD), yet they're considerably faster, so they are ordinarily employed for Operating Systems and apps on both PCs and hosting servers. An SSD is preferred as it doesn't have spinning disks that restrict its speed and can even cause overheating as it may happen with an HDD. Most companies work with SSDs for caching purposes, so all site content that is accessed more often will be stored on this kind of drives, while all the other content will be stored on standard HDDs. The main reason to use this kind of a configuration is to balance the cost and overall performance of their hosting platform and to lower the load on the HDDs caused by intense reading and writing processes.
SSD with Data Caching in Shared Hosting
The cloud platform where we create shared hosting accounts uses solely SSD drives, so your web applications and static Internet sites will load very quickly. The SSDs are used for files, emails and databases, so regardless if you open a page or check for new email messages with webmail, the content will load immediately. So as to ensure even better speeds, we also use a group of dedicated SSDs which work only as cache. All of the content which generates a lot of traffic is copied on them automatically and is afterwards read from them and not from the main storage drives. Of course, that content is replaced dynamically for much better efficiency. What we achieve by doing this except for the improved speed is decreased overall load, thus reduced probability 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 Servers
If you obtain one of our semi-dedicated server packages, your sites will be stored on a cloud platform that employs solely SSD drives for the storage of files, databases and e-mails. Along with the leading-edge ZFS file system that we use, this setup guarantees very fast loading speed for every web app hosted on our end. To ensure that the sites of one user don't affect the ones of another one, we also use numerous SSDs as cache - our system discovers files that are accessed more frequently and clones them, so that they start loading from the caching drives. The content on the latter is updated dynamically and as a result we can balance the load on all of the drives, ensure their extended life-span, reduce the risk of disk failures and, of course, supply a quick and reliable Internet hosting service.
