A solid-state drive (SSD) is a media which uses flash modules to store data. The SSDs are still relatively new and more pricey when compared to classic hard disk drives (HDD), but they're considerably faster, so they are quite often employed for Operating Systems and applications on both personal computers and servers. An SSD is recommended because it does not have spinning disks that limit its speed and could cause overheating as it could happen with an HDD. A number of companies employ SSDs for caching purposes, so all content that is accessed more often will be kept on such drives, while all the other content will be stored on conventional HDDs. The main reason to use this kind of a setup is to balance the cost and overall performance of their hosting platform and to lower the load on the HDDs resulting from numerous reading and writing processes.
SSD with Data Caching in Web Hosting
If you host your Internet sites in a web hosting account with us, you will definitely notice their fantastic performance. This is because our cloud platform uses only SSD drives for all of the files, emails and databases and we do not use HDDs for any part of the website hosting service. Along with the amazing ZFS file system, this configuration will increase the speed of your sites considerably. For load-balancing, we also use a number of SSDs for caching purposes only. Any content that generates increased traffic or causes a lot of reading/writing processes is duplicated on them promptly, so that the load on the main drives will be reduced, thus the overall performance of all websites hosted with us will be better. The abovementioned subsequently prolongs the life of the main drives and decreases the chance of a disk failure, that is a further warranty for the integrity of any content that you upload to your account.
SSD with Data Caching in Semi-dedicated Hosting
All semi-dedicated hosting accounts that we offer are created on a cloud platform that uses solely SSD drives. We don't use HDDs any longer, so your websites will load very quickly because we use SSDs for every aspect of the service - files, databases and e-mails. As some customers may host sites which are more popular than others, we also use many drives for caching. Our system identifies all of the content which is loaded more regularly and duplicates it on these drives in order to load it from them. This configuration is used for load-balancing purposes as we make sure that several reading/writing intensive sites will not affect the performance of the rest of the Internet sites that are stored on the same main drive. Using caching drives also raises the life-span of the main storage SSDs and lowers the chance of disk failures.
