A solid-state drive (SSD) is a media that uses flash modules in order to store info. The solid-state drives remain fairly new and more expensive when compared to standard hard disk drives (HDD), however they are much faster, so they are often employed for Operating Systems and applications on both desktops and hosting servers. An SSD is preferred because it doesn't have spinning disks that restrict its speed and may cause overheating like it could happen with an HDD. A number of companies employ SSDs for caching purposes, so any website content which is accessed more frequently will be held on this type of drives, while all the other content will be kept on conventional HDDs. The reason to use such a configuration is to balance the price and performance of their Internet hosting platform and to decrease the load on the HDDs resulting from countless reading and writing processes.
SSD with Data Caching in Cloud Hosting
The cloud platform where we create cloud hosting accounts uses exclusively SSD drives, so your web apps and static Internet sites will open very quickly. The SSDs are used for files, e-mails and databases, so no matter if you load a page or check for new e-mail messages using webmail, the content will load immediately. To ensure even better speeds, we also use a number of 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 primary storage drives. Needless to say, that content is replaced dynamically for improved performance. What we achieve by doing this except for the improved speed is lowered overall load, thus lower chance of hardware failures, and longer lifespan of the main drives, that is one more level of protection for any information that you upload to your account.
SSD with Data Caching in Semi-dedicated Hosting
All semi-dedicated hosting accounts that we provide are generated on a cloud platform that uses exclusively SSD drives. We don't use HDDs anymore, so your websites will load amazingly quickly because we employ SSDs for every part of the service - files, databases and email addresses. As some customers may host websites that can be more popular than others, we also use a number of drives for caching. Our system finds all the content which is accessed more often and duplicates it on these drives so as to load it from them. This setup is used for load-balancing purposes as we ensure that several reading/writing intensive websites will not influence the performance of the rest of the Internet sites that are stored on the same primary drive. Using caching drives also increases the lifespan of the main storage SSDs and reduces the potential for disk failures.
