A solid-state drive (SSD) is a media that uses flash modules to save info. The solid-state drives are still relatively new and more expensive than the classic hard disk drives (HDD), yet they are faster, so they are frequently employed for Operating Systems and apps on both desktops and web hosting servers. An SSD is recommended as it doesn't have spinning disks which limit its speed and may cause overheating as it may happen with an HDD. Numerous companies use SSDs for caching purposes, so all site content that is accessed more often will be stored on such drives, while all other content will be held on regular HDDs. The reason to use this kind of a configuration is to balance the price and performance of their hosting platform and to minimize the load on the HDDs resulting from numerous reading and writing processes.
SSD with Data Caching in Hosting
The cloud platform where we make hosting accounts uses solely SSD drives, so your web apps and static Internet sites will load extremely fast. The SSDs are used for files, e-mail addresses and databases, so no matter if you load a page or check for new emails through webmail, the content will load without delay. To ensure even greater speeds, we also use numerous dedicated SSDs that work only as cache. All the content which 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 improved efficiency. What we achieve by doing this except for the better speed is lowered overall load, thus lower probability of hardware failures, and prolonged lifespan of the main drives, that's one more level of protection for any info that you upload to your account.
SSD with Data Caching in Semi-dedicated Servers
All semi-dedicated server accounts that we provide are generated on a cloud platform that uses solely SSD drives. We don't use HDDs anymore, so your websites will load very fast since we employ SSDs for each aspect of the service - files, databases and e-mails. As some customers may host Internet sites which can be more popular than others, we also use multiple drives for caching. Our system finds all of the content which is accessed more frequently and clones it on these drives so as to load it from them. This setup is used for load-balancing purposes as we ensure that several reading/writing intensive websites will not affect the performance of the rest of the websites which are stored on the same primary drive. Using caching drives also increases the lifespan of the main storage SSDs and reduces the possibility of disk failures.
