A solid-state drive (SSD) is a media that uses flash modules so as to store info. The SSDs are still relatively new and more expensive than the classic hard disk drives (HDD), however they're considerably faster, so they are often employed for Operating Systems and applications on both home computer systems and web hosting servers. An SSD is preferred as it doesn't have spinning disks that limit its speed and may cause overheating like it could happen with an HDD. A large number of companies use SSDs for caching purposes, so all website content which is accessed more frequently will be kept on this type of drives, while all other content will be held on ordinary HDDs. The reason to use such a setup is to balance the price and overall performance of their website hosting platform and to lower the load on the HDDs caused by intense reading and writing processes.
SSD with Data Caching in Cloud Web Hosting
The cloud platform where we make cloud web 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 regardless of whether you load a page or check for new emails using webmail, the content will load without delay. To offer even greater speeds, we also use multiple dedicated SSDs which function only as cache. All the content that generates lots of traffic is copied on them automatically and is afterwards read from them and not from the primary storage drives. Of course, that content is replaced dynamically for improved efficiency. What we achieve that way in addition to the improved speed is reduced overall load, thus lower possibility of hardware failures, and prolonged lifespan of the primary drives, that is one more level of protection for any information that you upload to your account.
SSD with Data Caching in Semi-dedicated Servers
All semi-dedicated server accounts that we offer are made on a cloud platform which employs only SSD drives. We don't use HDDs anymore, so your websites will load quickly because we employ SSDs for every aspect of the service - files, databases and e-mails. Considering that some users may host sites that can be more popular than others, we also use numerous drives for caching. Our system finds all the content that is accessed more regularly and copies it on these drives so as to load it from them. This configuration is used for load-balancing purposes as we ensure that several reading/writing intensive websites will not affect the performance of the other websites which are stored on the very same primary drive. Using caching drives also increases the lifespan of the main storage SSDs and reduces the probability of disk failures.
