SSD with Data Caching in Shared Hosting
The cloud platform where we make shared hosting accounts uses exclusively SSD drives, so your web apps and static Internet sites will load very quickly. The SSDs are used for files, email addresses and databases, so regardless of whether you load a page or check for new emails through webmail, the content will load without delay. To ensure even higher speeds, we also use a number of dedicated SSDs which function only as cache. All the content which generates a lot of traffic is copied on them automatically and is afterwards read from them and not from the primary storage drives. Of course, that content is replaced dynamically for much better performance. What we achieve this way in addition to the better speed is decreased overall load, thus reduced chance of hardware failures, and extended lifespan of the main drives, which is one more level of security 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 created on a cloud platform which uses solely SSD drives. We don't use HDDs any longer, so your Internet sites will load very fast as we use SSDs for each aspect of the service - files, databases and email addresses. Considering that some users may host sites that can be more popular than others, we also use multiple drives for caching. Our system detects all of the content that 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 make sure that several reading/writing intensive Internet sites will not influence the performance of the rest of the Internet sites which are stored on the same primary drive. Using caching drives also raises the lifespan of the main storage SSDs and decreases the potential for disk failures.
