A solid-state drive (SSD) is a media that uses flash modules to save information. The SSDs are still relatively new and more expensive when compared to standard hard disk drives (HDD), but they're much faster, so they are quite often employed for Operating Systems and apps on both PCs and web servers. An SSD is recommended as it does not have spinning disks which restrict its speed and could cause overheating like it could happen with an HDD. A large number of companies use SSDs for caching purposes, so any website content that is accessed more often will be located on this kind of drives, while all other content will be held on ordinary HDDs. The reason to use this kind of a setup is to balance the cost and overall performance of their hosting platform and to decrease the load on the HDDs caused by countless reading and writing processes.
SSD with Data Caching in Shared Website Hosting
In case you host your websites in a shared website hosting account from us, you will definitely notice their excellent performance. The reason is that our cloud platform uses only SSD drives for all the files, emails and databases and we don't use HDDs for any part of the Internet hosting service. In addition to the leading-edge 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 increased traffic or creates a lot of reading/writing processes is copied on them promptly, so the load on the primary drives will be reduced, thus the overall performance of all Internet sites hosted on our end will improve. The latter subsequently prolongs the life of the primary drives and reduces the chance of a disk failure, which is one more guarantee for the reliability of any content that you upload to your account.
