A solid-state drive (SSD) is a media which uses flash modules to store info. The SSDs remain relatively new and more pricey compared to classic hard disk drives (HDD), yet they are much faster, so they are ordinarily employed for Operating Systems and apps on both PCs and web servers. An SSD is recommended because it doesn't have spinning disks which restrict its speed and could cause overheating as it could happen with an HDD. Lots of companies use SSDs for caching purposes, so all of the site content that is accessed more often will be held on such drives, while all other content will be located on regular HDDs. The reason to use such a setup is to balance the cost and performance of their web hosting platform and to decrease the load on the HDDs caused by numerous reading and writing processes.
SSD with Data Caching in Shared Hosting
We use only SSDs on our state-of-the-art cloud web hosting platform and we have eliminated all HDDs on our production servers as to ensure lightning-fast loading speeds for every part of our services - files, e-mails and databases. Thus, any content that you upload to your shared hosting account will be accessible very fast. To boost the overall performance of the sites hosted on our end even more, we also use a number of SSDs which work only as cache - our system saves often accessed content on them and updates it instantly. We employ this kind of a setup to make sure that traffic-intensive sites don't influence the performance of the other sites hosted on our platform and this way all other websites can also take advantage of the speed which the SSD drives provide. Furthermore, since the load on the main drives is decreased, their lifespan shall be longer, that is one more guarantee for the safety and integrity of your information.
SSD with Data Caching in Semi-dedicated Servers
All semi-dedicated server accounts that we provide are made on a cloud platform which employs only SSD drives. We do not use HDDs anymore, so your Internet sites will load very fast since we use SSDs for all aspects of the service - files, databases and e-mails. Considering that some users may host sites that could be more popular than others, we also use numerous drives for caching. Our system identifies all of the content that is loaded more regularly and duplicates it on these drives so as to load it from them. This configuration is used for load-balancing purposes as we guarantee that several reading/writing intensive websites will not influence the performance of the rest of the sites which are stored on the same main drive. Using caching drives also raises the life-span of the main storage SSDs and decreases the chance of disk failures.
