RAID in Web Hosting
The revolutionary cloud Internet hosting platform where all web hosting accounts are created uses super fast SSD drives as opposed to the classic HDDs, and they function in RAID-Z. With this setup, numerous hard disks function together and at least one of them is a dedicated parity disk. Put simply, when data is written on the rest of the drives, it's cloned on the parity one adding an extra bit. This is done for redundancy as even if a 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, so absolutely nothing will be lost and there won't be any service interruptions. This is an additional level of security for your info in addition to the revolutionary ZFS file system which uses checksums to ensure that all the data on our servers is intact and is not silently corrupted.
RAID in Semi-dedicated Servers
If you host your sites inside a semi-dedicated server account from our company, any content you upload will be saved on SSD drives which operate in RAID-Z. With this kind of RAID, at least 1 of the drives is used for parity - when data is synced between the drives, an additional bit is included in it on the parity one. The reasoning behind this is to ensure the integrity of the data that is cloned to a brand new drive in case one of the drives in the RAID fails as the website content being copied on the new disk is recalculated from the info on the standard disk drives and on the parity one. Another advantage of RAID-Z is that even in the event that a disk drive stops functioning, the system could switch to a different one immediately without service interruptions of any sort. RAID-Z adds an extra level of protection for the content which you upload on our cloud hosting platform along with the ZFS file system which uses unique checksums so as to validate the integrity of each file.
RAID in VPS Servers
The physical servers where we create VPS server employ quick SSD drives that will boost the speed of your Internet sites considerably. The disk drives function in RAID to ensure that you won't lose any information as a result of a power loss or a hardware malfunction. The production servers employ many different drives where the info is kept and one disk is used for parity i.e. one bit is added to all the data copied on it, that makes it easier to restore the content without loss in the event a main drive breaks down. In case you use our backup service, the information will be stored on a separate machine that uses standard hard-disk drives and despite the fact that there is no parity one in this case, they are also in a RAID to ensure that we will have a backup of your website content all of the time. With this type of setup your data will always be safe as it will be available on many drives.
