A solid-state drive is really quicker than any conventional hard disk. It is because a hard-disk drive uses spinning disks, which can rotate only so fast and the more data is read and written, the slower and warmer they become, at the same time an SDD employs modules of flash memory, therefore there are no physically moving components. The access speeds for an SSD are much higher, which makes these drives a preferred solution when speed is needed. That's why SSDs are in many cases used for the Operating System on a desktop or notebook and for storing data which is used often on web servers. A lot of providers also use a combination of the two drives, so they keep the data on HDDs, but they use one or more SSDs in order to cache the more often used data and because of this, the data loads quicker while the load on the HDDs is reduced since their disks need to spin less often to read and write.
SSD with Data Caching in Shared Hosting
The cloud platform where we make shared hosting accounts uses exclusively SSD drives, so your web apps and static websites will load very fast. The SSDs are used for files, email addresses and databases, so no matter if you load a page or check for new email messages using webmail, the content will load very quickly. In order to offer even better speeds, we also use numerous dedicated SSDs that work only as cache. All of the content that generates lots of traffic is copied on them automatically and is afterwards read from them and not from the main storage drives. Of course, that content is replaced dynamically for much better efficiency. What we achieve in this way apart from the better speed is lowered overall load, thus decreased possibility of hardware failures, and prolonged lifespan of the main drives, that's one more level of protection for any data that you upload to your account.
SSD with Data Caching in Semi-dedicated Servers
If you want speed and excellent performance for your sites, our semi-dedicated server accounts shall be a very suitable solution as they're made on a cloud platform that employs SSDs for each part of the service - emails, databases and files. That way, every website that you host on our end will load fast. Just like other companies, we also use SSDs for caching, but since all storage drives are solid-state ones, you will be able to take advantage of the good performance all of the time and irrespective of the nature of your sites. The caching drives are used for load-balancing and any frequently accessed content is copied to them, which both lowers the load and provides the fantastic performance of all websites which load from the main drives. The lifespan of the latter will also be increased considering that there will be significantly less reading and writing processes on them.
