SSD with Data Caching in Shared Hosting
The cloud platform where we make shared hosting accounts uses only SSD drives, so your web applications and static sites will open very quickly. The SSDs are used for files, email addresses and databases, so regardless of whether you open a page or check for new e-mails through webmail, the content will load without delay. In order to offer even greater speeds, we also use numerous dedicated SSDs that function only as cache. All the content that generates a lot of traffic is copied on them automatically and is afterwards read from them and not from the main storage drives. Of course, that content is replaced dynamically for much better efficiency. What we achieve this way apart from the better speed is lowered overall load, thus decreased 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 Hosting
All semi-dedicated hosting accounts that we provide are generated on a cloud platform that uses solely SSD drives. We do not use HDDs anymore, so your Internet sites will load very fast as we use SSDs for each aspect of the service - files, databases and e-mails. Considering that some people may host Internet sites that can be more frequently visited than others, we also use multiple drives for caching. Our system discovers all the content which is accessed more regularly 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 affect the performance of the rest of the websites that are stored on the very same main drive. Using caching drives also raises the life-span of the main storage SSDs and decreases the potential for disk failures.
