SSD with Data Caching in Shared Hosting
The cloud platform where we make shared hosting accounts uses only SSD drives, so your web apps and static sites will open very quickly. The SSDs are used for files, e-mail addresses and databases, so regardless of whether you open a page or check for new emails through webmail, the content will load without delay. In order to ensure even higher speeds, we also use multiple dedicated SSDs that function only as cache. All the content which generates lots 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 aside from the improved speed is lowered overall load, thus decreased chance of hardware failures, and extended lifespan of the main drives, that's one more level of protection for any info 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 do not use HDDs any longer, so your websites will load very fast because we use SSDs for each aspect of the service - files, databases and emails. Considering that some users may host websites that could be more popular than others, we also use a number of drives for caching. Our system identifies all of the content which is loaded more frequently and copies 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 Internet sites will not influence the performance of the other Internet sites that are stored on the very same primary drive. Using caching drives also raises the life-span of the main storage SSDs and decreases the potential for disk failures.
