A solid-state drive (SSD) is a media which uses flash modules so as to store information. The SSDs remain relatively new and more pricey compared to classic hard disk drives (HDD), yet they're faster, so they are often used for Operating Systems and apps on both home computer systems and hosting servers. An SSD is preferred as it doesn't have spinning disks which restrict its speed and can cause overheating as it may happen with an HDD. A number of companies employ SSDs for caching purposes, so any content which is accessed more frequently will be stored on such drives, while all other content will be located on conventional HDDs. The reason to use this kind of a setup is to balance the price and performance of their web hosting platform and to lower the load on the HDDs caused by numerous reading and writing processes.
SSD with Data Caching in Cloud Hosting
The cloud platform where we make cloud hosting accounts uses solely SSD drives, so your web apps and static sites will open very fast. The SSDs are used for files, e-mails and databases, so regardless if you load a page or check for new messages with webmail, the content will load without delay. So as to ensure even better speeds, we also use a group of dedicated SSDs that function only as cache. All of the content that generates lots of traffic is copied on them automatically and is later on read from them and not from the primary storage drives. Of course, that content is replaced dynamically for better efficiency. What we achieve that way in addition to the improved speed is decreased overall load, thus reduced chance of hardware failures, and prolonged lifespan of the primary drives, that is one more level of security for any data that you upload to your account.
SSD with Data Caching in Semi-dedicated Hosting
All semi-dedicated hosting accounts that we offer are created on a cloud platform that uses exclusively SSD drives. We do not use HDDs anymore, so your sites will load quickly since we employ SSDs for each aspect of the service - files, databases and emails. Considering that some people may host websites which could be more frequently visited than others, we also use multiple drives for caching. Our system finds any content which is loaded more frequently and clones it on these drives so as to load it from them. This setup is used for load-balancing purposes as we guarantee that several reading/writing intensive websites will not affect the performance of the rest of the Internet sites that are stored on the very same primary drive. Using caching drives also increases the life-span of the main storage SSDs and lowers the potential for disk failures.
