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 websites will open extremely fast. The SSDs are used for files, email addresses and databases, so no matter if you load a page or check for new e-mails using webmail, the content will load quickly. So as to ensure even greater speeds, we also use a group of dedicated SSDs which work only as cache. All the content which generates lots of traffic is copied on them automatically and is later on read from them and not from the primary storage drives. Needless to say, that content is replaced dynamically for much better performance. What we achieve by doing this except for the better speed is decreased overall load, thus lower chance of hardware failures, and longer lifespan of the main drives, that is one more level of security for any info 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 exclusively SSD drives. We don't use HDDs any longer, so your websites will load quickly because we employ SSDs for every part of the service - files, databases and e-mails. Considering that some users may host sites which are more popular than others, we also use many drives for caching. Our system discovers all the content that is loaded more often and clones 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 sites will not influence the performance of the rest of the websites that are stored on the very same main drive. Using caching drives also increases the lifespan of the main storage SSDs and lowers the chance of disk failures.
