RAID in Shared Web Hosting
The state-of-the-art cloud web hosting platform where all shared web hosting accounts are generated uses fast NVMe drives instead of the traditional HDDs, and they work in RAID-Z. With this configuration, a number of hard drives operate together and at least a single one is a dedicated parity disk. In simple terms, when data is written on the remaining drives, it's copied on the parity one adding an extra bit. This is carried out for redundancy as even if some drive fails or falls out of the RAID for whatever reason, the data can be rebuilt and verified thanks to the parity disk and the data recorded on the other ones, thus practically nothing will be lost and there will not be any service disorders. This is one more level of protection for your info in addition to the top-notch ZFS file system which uses checksums to make sure that all of the data on our servers is intact and is not silently corrupted.
RAID in VPS Servers
If you employ one of our VPS server plans, any content which you upload will be saved on NVMe drives which function in RAID. At least 1 drive is intended for parity so as to guarantee the integrity of your information. In simple terms, this is a special drive where information is copied with one bit added to it. If a disk inside the RAID fails, your websites will continue working and when a new disk replaces the defective one, the bits of the information that will be duplicated on it are calculated using the healthy and the parity drives. That way, any chance of corrupting data during the process is prevented. We also use conventional hard disk drives which work in RAID for storing backup copies, so should you add this service to your VPS package, your site content will be stored on multiple drives and you won't ever need to worry about its integrity even in the event of multiple drive breakdowns.
