A solid-state drive (SSD) improves the performance of each application running on it compared to an ordinary hard-disk drive (HDD). The reason is that an SSD uses a number of interconnected flash memory modules, so there're no physical parts to move. In contrast, a hard disk employs spinning disks and every reading or writing process causes the disks to move, meaning the speed of an HDD is limited. Since the cost of the two kinds of drives also differ, many computer systems and web servers are set up with an SSD for the operating system and various applications, and a hard disk for file storage, thus balancing price and effectiveness. A web hosting provider can also use a solid-state drive for caching purposes, which means that files that are used very often will be located on such a drive for accomplishing higher loading speeds and for reducing the reading/writing processes on the hard disks.
SSD with Data Caching in Cloud Website Hosting
The cloud platform where we make cloud website hosting accounts uses exclusively SSD drives, so your web applications and static Internet sites will load 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 very quickly. So as to ensure even higher speeds, we also use multiple dedicated SSDs which work only as cache. All content that 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 better performance. What we achieve by doing this in addition to the improved speed is decreased overall load, thus decreased probability of hardware failures, and extended 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 Servers
All semi-dedicated server accounts that we provide are generated on a cloud platform that uses only SSD drives. We do not use HDDs any longer, so your Internet sites will load quickly since we use SSDs for all aspects of the service - files, databases and e-mail addresses. Considering that some users may host sites that could be more frequently visited than others, we also use many drives for caching. Our system finds any content which is loaded more often and copies it on these drives in order to load it from them. This configuration is used for load-balancing purposes as we guarantee that several reading/writing intensive Internet sites will not influence the performance of the rest of the websites which are stored on the very same main drive. Using caching drives also increases the lifespan of the main storage SSDs and reduces the chance of disk failures.
