RAID
See the advantages of having your websites and applications hosted on a RAID-enabled hosting server.
Redundant Array of Independent Disks, or RAID, is a method of saving content on multiple hard disks simultaneously. A RAID could be software or hardware depending on the HDDs which are used - physical or logical ones, yet what is common between them is the fact that they all operate as a single unit where information is saved. The top advantage of using a RAID is redundancy as the info on all drives shall be exactly the same all of the time, so even if a drive fails for some reason, the information will still be present on the remaining drives. The general performance is enhanced as well as the reading and writing processes can be split between multiple drives, so a single one will never be overloaded. There're different types of RAIDs where the efficiency and fault tolerance can vary depending on the particular setup - whether your data is written on all the drives real-time or it is written on a single drive and after that mirrored on another, the number of drives are used for the RAID, etcetera.
RAID in Cloud Web Hosting
Any content that you upload to your new cloud web hosting account will be held on quick NVMe drives that operate in RAID-Z. This configuration is built to work with the ZFS file system that runs on our cloud hosting platform and it adds one more level of security for your content on top of the real-time checksum verification that ZFS uses to ensure the integrity of the data. With RAID-Z, the info is stored on a couple of disks and at least one is a parity disk - whenever data is written on it, an extra bit is added, so in the event that any drive fails for some reason, the integrity of the data can be verified by recalculating its bits based on what is stored on the production drives and on the parity one. With RAID-Z, the functioning of our system will never be interrupted and it will continue working efficiently until the problematic drive is replaced and the info is synced on it.
