A solid-state drive (SSD) is a media that uses flash modules to save data. The solid-state drives remain relatively new and more pricey when compared to classic hard disk drives (HDD), but they are much faster, so they are quite often used for Operating Systems and applications on both PCs and web hosting servers. An SSD is preferred as it doesn't have spinning disks that limit its speed and can even cause overheating like it may happen with an HDD. Most companies use SSDs for caching purposes, so all the content which is accessed more frequently will be kept on this kind of drives, while all other content will be held on conventional HDDs. The reason to use such a setup is to balance the price and performance of their hosting platform and to minimize the load on the HDDs resulting from countless 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 fantastic performance. This is because our cloud platform uses only SSD drives for all files, e-mail addresses and databases and we don't use HDDs for any part of the web hosting service. In addition to the leading-edge ZFS file system, this setup will raise the speed of your websites substantially. For load-balancing, we also use a number of SSDs for caching purposes only. All of the content that generates increased traffic or causes lots of reading/writing processes is copied on them instantly, so the load on the main drives will be lower, thus the overall performance of all websites hosted with us will improve. The abovementioned in turn prolongs the life of the main drives and decreases the possibility of a disk failure, that is a further guarantee for the integrity of any content which you upload to your account.
