A solid-state drive (SSD) is a media which uses flash modules so as to store info. The solid-state drives remain fairly new and more pricey compared to standard hard disk drives (HDD), but they are much faster, so they are quite often used for Operating Systems and applications on both desktops and servers. An SSD is preferred because it does not have spinning disks which limit its speed and can even cause overheating as it could happen with an HDD. Lots of companies use SSDs for caching purposes, so any website content which is accessed more frequently will be held on this type of drives, while all the other content will be stored on conventional HDDs. The main reason to use such a configuration is to balance the cost and overall performance of their hosting platform and to reduce the load on the HDDs resulting from countless reading and writing processes.
SSD with Data Caching in Shared Hosting
If you host your sites in a shared hosting account from us, you will definitely notice their exceptional performance. This is because our cloud platform uses only SSD drives for all files, e-mails and databases and we do not use HDDs for any part of the web hosting service. Along with the state-of-the-art ZFS file system, this configuration will increase the speed of your sites significantly. For load-balancing, we also use a number of SSDs for caching purposes only. All content that generates more traffic or creates a lot of reading/writing processes is copied on them promptly, so that the load on the main drives will be lower, thus the overall performance of all sites hosted with us will be better. The latter subsequently prolongs the life of the main drives and decreases the chance of a disk failure, that is another warranty for the reliability of all content which you upload to your account.
SSD with Data Caching in Semi-dedicated Servers
All semi-dedicated server accounts that we offer are generated on a cloud platform which employs only SSD drives. We do not use HDDs anymore, so your sites will load very quickly since we use SSDs for each aspect of the service - files, databases and e-mails. As some people may host Internet sites which could be more frequently visited than others, we also use many drives for caching. Our system identifies any content that is loaded more frequently and clones it on these drives so as to load it from them. This configuration is used for load-balancing purposes as we ensure that several reading/writing intensive websites will not affect the performance of the other websites that are stored on the same primary drive. Using caching drives also raises the life-span of the main storage SSDs and reduces the chance of disk failures.
