A solid-state drive (SSD) enhances the performance of any application running on it in comparison with a classic hard-disk drive (HDD). The reason is that an SSD employs a variety of interconnected flash memory units, so there're no physical parts to move. In comparison, a hard disk contains spinning disks and every reading or writing process causes the disks to rotate, meaning the speed of an HDD is limited. Since the cost of the two types of drives are different as well, lots of computer systems and web servers are set up with an SSD for the OS and various applications, and a hard-disk drive for file storage, thus balancing cost and effectiveness. A hosting service provider may also use an SSD for caching purposes, so files that are accessed on a regular basis will be kept on such a drive for achieving better loading speeds and for reducing the reading/writing processes on the HDDs.
SSD with Data Caching in Cloud Website Hosting
If you host your websites in a cloud website hosting account from our company, you'll definitely notice their fantastic performance. This is because our cloud platform uses only SSD drives for all files, emails and databases and we don't use HDDs for any part of the web hosting service. Along with the amazing ZFS file system, this setup will raise the speed of your websites tremendously. For load-balancing, we also use numerous SSDs for caching purposes only. All the content which generates more traffic or causes a lot of reading/writing processes is duplicated on them automatically, so that the load on the primary drives will be lower, thus the overall performance of all websites hosted with us will be better. This subsequently prolongs the life of the main drives and lessens the chance of a disk failure, that is one more warranty for the integrity of all content which you upload to your account.
