A solid-state drive (SSD) is a media which uses flash modules so as to save data. The SSDs are still fairly new and more expensive than the standard hard disk drives (HDD), yet they are considerably faster, so they are quite often used for Operating Systems and applications on both desktops and hosting servers. An SSD is preferred as it doesn't have spinning disks that limit its speed and may even cause overheating like it may happen with an HDD. A number of companies employ SSDs for caching purposes, so all the site content which is accessed more frequently will be kept on such drives, while all the other content will be kept on conventional HDDs. The main reason to use this kind of a configuration is to balance the cost and performance of their Internet hosting platform and to decrease the load on the HDDs caused by countless reading and writing processes.
SSD with Data Caching in Hosting
The cloud platform where we make hosting accounts uses only SSD drives, so your web apps and static sites will load extremely 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 with webmail, the content will load without delay. To offer even higher speeds, we also use multiple dedicated SSDs that function only as cache. All content which generates lots of traffic is copied on them automatically and is later read from them and not from the main storage drives. Of course, that content is replaced dynamically for better efficiency. What we achieve this way aside from the better speed is reduced overall load, thus reduced probability of hardware failures, and extended lifespan of the main drives, that's one more level of protection for any data that you upload to your account.
SSD with Data Caching in Semi-dedicated Hosting
If you purchase one of our semi-dedicated hosting plans, your websites will be stored on a cloud platform that employs exclusively SSD drives for the storing of files, databases and emails. Together with the cutting-edge ZFS file system that we use, this configuration guarantees fast loading speed for every web app hosted on our end. To guarantee that the Internet sites of one customer do not affect the ones of another one, we also use numerous SSDs as cache - our system finds files which are accessed more frequently and copies them, so that they start loading from the caching drives. The content on the latter is refreshed dynamically and as a result we can balance the load on all drives, ensure their long lifespan, decrease the risk of disk failures and, of course, supply a fast and reliable Internet hosting service.
