A solid-state drive (SSD) is a media which uses flash modules so as to store data. The SSDs remain relatively new and more expensive than the classic hard disk drives (HDD), yet they are considerably faster, so they are quite often used for Operating Systems and apps on both personal computers and hosting servers. An SSD is preferred because it doesn't have spinning disks which limit its speed and may even cause overheating as it may happen with an HDD. Numerous companies work with SSDs for caching purposes, so all of the website content that is accessed more frequently will be located on this type of drives, while all other content will be stored on standard HDDs. The reason to use this kind of a setup is to balance the price and overall performance of their hosting platform and to minimize the load on the HDDs resulting from intense reading and writing processes.
SSD with Data Caching in Shared Hosting
The cloud platform where we create shared hosting
accounts uses solely SSD drives, so your web apps and static Internet sites will load very quickly. The SSDs are used for files, emails and databases, so no matter if you open a page or check for new e-mails using webmail, the content will load right away. In order to ensure even higher 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 afterwards read from them and not from the primary storage drives. Of course, that content is replaced dynamically for much better efficiency. What we achieve by doing this apart from the improved speed is lowered overall load, thus lower probability of hardware failures, and longer lifespan of the main drives, that is 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 employs solely SSD drives. We don't use HDDs any longer, so your websites will load amazingly quickly since we employ SSDs for every part of the service - files, databases and email addresses. Considering that some users may host sites that are more popular than others, we also use many drives for caching. Our system finds all of the content that is loaded more often and duplicates it on these drives so as to load it from them. This configuration is used for load-balancing purposes as we guarantee that several reading/writing intensive sites will not influence the performance of the other sites which are stored on the very same main drive. Using caching drives also raises the lifespan of the main storage SSDs and lowers the possibility of disk failures.
