A solid-state drive is substantially quicker than any regular hard disk. The reason is that an HDD uses spinning disks, which can rotate only so fast and the more info is read and written, the slower and warmer they become, while an SDD employs modules of flash memory, so there aren't any actually moving parts. The access speeds for an SSD are significantly higher, which makes these drives an ideal solution in case speed is needed. That's why SSDs are frequently employed for the Operating System on a desktop or notebook and for keeping data that's used regularly on servers. Many providers also use a combination of the two drives, so they store the data on hard-disks, but they use a couple of solid-state drives in order to cache the more often used data and consequently, the data loads much quicker while the load on the HDDs is lowered because their disks need to spin less frequently to read and write.
SSD with Data Caching in Shared Web Hosting
Our modern cloud hosting platform employs only SSD drives, so if you obtain any of our shared web hosting
solutions, you can take full advantage of the speed that these drives provide. We no longer use hard drives, so your files, databases and emails will all load from high-speed SSDs. For even greater performance, we use caching solid-state drives. A group of drives are used by our system for each file that is accessed more frequently and the data on these drives is dynamically refreshed in order to make sure that all of the traffic-intensive files load from them. In this way, the load on the primary drives is lowered, so we can provide excellent performance for all kinds of websites irrespective of how many times they are accessed and avoid a situation where some Internet sites are affected by an excessive number of reading and writing processes generated by others. This setup also increases the lifespan of the primary drives and reduces the chance of disk failure.
