A solid-state drive (SSD) is a media that uses flash modules so as to store info. The solid-state drives are still fairly new and more expensive than the classic hard disk drives (HDD), however they are faster, so they are often used for Operating Systems and apps on both personal computers and web servers. An SSD is preferred because it doesn't have spinning disks which limit its speed and may even cause overheating like it may happen with an HDD. A large number of companies work with SSDs for caching purposes, so all of the site content that is accessed more often will be held on this type of drives, while all other content will be stored on regular HDDs. The reason to use such a configuration is to balance the cost and performance of their hosting platform and to reduce the load on the HDDs resulting from numerous reading and writing processes.
SSD with Data Caching in Website Hosting
The cloud platform where we create website hosting
accounts uses exclusively SSD drives, so your web applications and static Internet sites will load very fast. The SSDs are used for files, e-mails and databases, so no matter if you open a page or check for new e-mail messages through webmail, the content will load quickly. So as to ensure even better speeds, we also use a group of dedicated SSDs that function only as cache. All content that generates lots of traffic is copied on them automatically and is later on read from them and not from the primary storage drives. Of course, that content is replaced dynamically for better efficiency. What we achieve in this way aside from the improved speed is reduced overall load, thus reduced chance of hardware failures, and extended lifespan of the main drives, that's one more level of security for any info that you upload to your account.
SSD with Data Caching in Semi-dedicated Servers
Provided you want speed and high-end performance for your sites, our semi-dedicated server
accounts shall be a very suitable solution since they're made on a cloud platform that uses SSDs for every part of the service - e-mails, databases and files. This way, each and every site that you host here will load fast. Just like other providers, we also use SSDs for caching, but since all storage drives are solid-state ones, you will be able to take advantage of the top performance at all times and regardless of the type of your websites. The caching solid-state drives are used for load-balancing and any frequently accessed content is copied on them, which both reduces the load and ensures the good performance of all websites that load straight from the main drives. The lifespan of the latter will also be increased as there will be substantially less reading and writing processes on them.
