A solid-state drive (SSD) improves the performance of each app running on it as compared with a regular hard-disk drive (HDD). The reason is that an SSD uses a number of interconnected flash memory units, 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 spin, so the speed of an HDD is restricted. As the cost of the two kinds of drives also differ, many computer systems and web servers are equipped with an SSD for the operating system and various applications, and a hard-disk drive for file storage, in this way balancing price and effectiveness. A web hosting service provider may also use a solid-state drive for caching purposes, so files which are used very often will be saved on this type of a drive for reaching higher loading speeds and for limiting the reading/writing processes on the hard disks.
SSD with Data Caching in Website Hosting
The cloud platform where we create website hosting accounts uses only SSD drives, so your web applications and static websites will load very quickly. The SSDs are used for files, email addresses and databases, so no matter if you open a page or check for new e-mail messages through webmail, the content will load right away. So as to ensure even greater speeds, we also use multiple dedicated SSDs that work only as cache. All content that generates lots of traffic is copied on them automatically and is later read from them and not from the primary storage drives. Of course, that content is replaced dynamically for better performance. What we achieve by doing this apart from the improved speed is decreased overall load, thus lower chance of hardware failures, and longer lifespan of the main drives, which is one more level of security for any data that you upload to your account.
SSD with Data Caching in Semi-dedicated Hosting
If you sign up for one of our semi-dedicated hosting solutions, we will save your content on SSD drives and this is valid not only for the files, but also for all of the databases and email messages. This way, your script-driven apps and webmail will load extremely fast. We employ dedicated SSDs for caching too. Traffic-intensive website content is copied automatically on these drives, so we make certain that a number of heavy websites that generate a large amount of reading and writing processes will not influence the other Internet sites which share the exact same drive. By reduction of the overall system load we also increase the lifespan of the main storage drives and lower the potential for a disk failure, so by using SSD drives for caching purposes, we add another level of security for your website content.
