SSD with Data Caching in Shared Hosting
The cloud platform where we make shared hosting accounts uses exclusively 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 of whether you load a page or check for new e-mail messages with webmail, the content will load immediately. In order to ensure even higher speeds, we also use numerous dedicated SSDs that function only as cache. Any content that 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 much better efficiency. What we achieve that way aside from the improved speed is reduced overall load, thus lower chance of hardware failures, and longer lifespan of the primary drives, that's one more level of protection for any data that you upload to your account.
SSD with Data Caching in Semi-dedicated Servers
All semi-dedicated server accounts that we provide are made on a cloud platform which uses only SSD drives. We do not use HDDs anymore, so your websites will load very quickly because we use SSDs for all aspects of the service - files, databases and emails. As some people may host websites which can be more frequently visited than others, we also use multiple drives for caching. Our system detects all of the content which is loaded more regularly and clones it on these drives in order 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 sites that are stored on the same primary drive. Using caching drives also increases the lifespan of the main storage SSDs and lowers the chance of disk failures.
