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 if you open a page or check for new messages through webmail, the content will load promptly. To offer even higher speeds, we also use multiple dedicated SSDs which work only as cache. All content which generates lots 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 better efficiency. What we achieve by doing this except for the improved speed is reduced overall load, thus decreased potential for hardware failures, and prolonged 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 which uses solely SSD drives. We don't use HDDs anymore, so your sites will load quickly since we use SSDs for all aspects of the service - files, databases and e-mails. Considering that some users may host sites that could be more popular than others, we also use numerous drives for caching. Our system identifies any content which is accessed more frequently and duplicates 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 affect the performance of the rest of the websites that are stored on the very same primary drive. Using caching drives also raises the lifespan of the main storage SSDs and decreases the potential for disk failures.
