A solid-state drive (SSD) is a media which uses flash modules in order to store information. The solid-state drives remain relatively new and more expensive compared to standard hard disk drives (HDD), however they're considerably faster, so they are quite often used for Operating Systems and applications on both PCs and web hosting servers. An SSD is recommended because it doesn't have spinning disks that limit its speed and may even cause overheating as it could happen with an HDD. A lot of companies use SSDs for caching purposes, so all of the website content that is accessed more often will be stored on such drives, while all the other content will be kept on standard HDDs. The main reason to use this type of a setup is to balance the cost and overall performance of their web hosting platform and to reduce the load on the HDDs resulting from intense reading and writing processes.
SSD with Data Caching in Shared Hosting
The cloud platform where we make shared hosting accounts uses solely SSD drives, so your web apps and static sites will load very quickly. The SSDs are used for files, e-mails and databases, so regardless if you open a page or check for new e-mails with webmail, the content will load immediately. In order to ensure even greater speeds, we also use multiple dedicated SSDs that work only as cache. All of the content which generates a lot of traffic is copied on them automatically and is afterwards read from them and not from the primary storage drives. Needless to say, that content is replaced dynamically for improved efficiency. What we achieve that way except for the better speed is decreased overall load, thus decreased chance of hardware failures, and extended lifespan of the main drives, that's one more level of security for any data that you upload to your account.
SSD with Data Caching in Semi-dedicated Hosting
If you want speed and fantastic performance for your Internet sites, our semi-dedicated hosting accounts shall be a really suitable solution as they're made on a cloud platform that uses SSDs for every part of the service - e-mail addresses, databases and files. This way, each and every website that you host on our end will load fast. Just like other providers, we also use SSDs for caching, but since all storage drives are solid-state ones, you can take advantage of the good performance at all times and whatever the type of your websites. The caching drives are used for load-balancing and all the frequently accessed content is copied to them, which both reduces the load and guarantees the good performance of all websites that load straight from the main drives. The lifespan of the latter is also increased since there'll be significantly less reading and writing processes on them.
