A solid-state drive (SSD) improves the performance of any application running on it compared to a regular hard-disk drive (HDD). The reason is that an SSD employs multiple interconnected flash memory modules, so there're no physical parts to move. In contrast, a hard disk uses spinning disks and any reading or writing process causes the disks to move, which means that the speed of an HDD is restricted. As the prices of the two kinds of drives are also different, a large number of desktops and web servers are equipped with an SSD for the OS and random applications, and an HDD for data storage, in this way balancing price and performance. A website hosting provider can also use a solid-state drive for caching purposes, which means that files that are used regularly will be stored on such a drive for reaching higher loading speeds and for limiting the reading/writing processes on the hard-disk drives.
SSD with Data Caching in Shared Website Hosting
In case you host your sites in a shared website hosting account with us, you'll notice their exceptional performance. The reason is that our cloud platform uses solely SSD drives for all the files, emails and databases and we do not use HDDs for any part of the web hosting service. Together with the advanced ZFS file system, this setup will increase the speed of your websites substantially. For load-balancing, we also use multiple SSDs for caching purposes only. Any content which generates more traffic or causes a lot of reading/writing processes is copied on them instantly, so the load on the main drives will be reduced, thus the overall performance of all sites hosted on our end will be better. The abovementioned subsequently prolongs the life of the main drives and decreases the chance of a disk failure, that is another guarantee for the reliability of all content that you upload to your account.
SSD with Data Caching in Semi-dedicated Hosting
All semi-dedicated hosting accounts that we offer are created on a cloud platform that uses only SSD drives. We don't use HDDs any longer, so your Internet sites will load very fast as we use SSDs for every part of the service - files, databases and e-mail addresses. As some users may host websites which are more frequently visited than others, we also use a number of drives for caching. Our system discovers all the content that is loaded more frequently and copies it on these drives in order to load it from them. This configuration is used for load-balancing purposes as we make sure that several reading/writing intensive Internet sites will not affect the performance of the rest of the Internet sites that are stored on the same main drive. Using caching drives also increases the lifespan of the main storage SSDs and reduces the probability of disk failures.
