A solid-state drive (SSD) is a media that uses flash modules to save info. The SSDs remain fairly new and more expensive than the standard hard disk drives (HDD), but they're considerably faster, so they are frequently employed for Operating Systems and applications on both personal computers and servers. An SSD is preferred as it doesn't have spinning disks that restrict its speed and can even cause overheating like it may happen with an HDD. Lots of companies work with SSDs for caching purposes, so any site content which is accessed more often will be stored on such drives, while all other content will be held on standard HDDs. The main reason to use this kind of a setup is to balance the price and performance of their web hosting platform and to minimize the load on the HDDs caused by intense reading and writing processes.
SSD with Data Caching in Shared Hosting
If you host your websites in a shared hosting account with us, you'll definitely notice their excellent 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 hosting service. In addition to the amazing ZFS file system, this configuration will increase the speed of your websites tremendously. For load-balancing, we also use multiple SSDs for caching purposes only. All the content that generates increased traffic or causes a lot of reading/writing processes is copied on them promptly, so that the load on the main drives will be reduced, thus the overall performance of all Internet sites hosted with us will be better. The latter in turn prolongs the life of the main drives and lessens the possibility of a disk failure, which is another warranty for the integrity of all content that you upload to your account.
