RAID in Hosting
The hard disks that we employ for storage with our state-of-the-art cloud Internet hosting platform are not the classic HDDs, but super fast NVMes. They function in RAID-Z - a special setup developed for the ZFS file system which we use. All the content that you upload to the hosting account will be held on multiple drives and at least one shall be used as a parity disk. This is a special drive where an extra bit is added to any content copied on it. In the event that a disk in the RAID stops functioning, it'll be replaced with no service interruptions and the info will be rebuilt on the new drive by recalculating its bits using the data on the parity disk plus that on the remaining disks. This is done so as to guarantee the integrity of the data and along with the real-time checksum authentication that the ZFS file system runs on all drives, you won't ever need to worry about losing any information no matter what.
RAID in Semi-dedicated Servers
The data uploaded to any semi-dedicated server account is stored on NVMe drives which operate in RAID-Z. One of the drives in type of a setup is used for parity - whenever data is copied on it, an additional bit is added. In case a disk happens to be defective, it will be removed from the RAID without interrupting the operation of the Internet sites as the data will load from the other drives, and when a brand new drive is included, the information that will be duplicated on it will be a combination between the info on the parity disk and data saved on the other drives in the RAID. This is done so as to guarantee that the information that is being cloned is correct, so as soon as the new drive is rebuilt, it could be included in the RAID as a production one. This is an extra warranty for the integrity of your data because the ZFS file system which runs on our cloud hosting platform analyzes a special checksum of all copies of the files on the separate drives to be able to avoid any chance of silent data corruption.
RAID in VPS Servers
The physical servers where we make VPS server use fast NVMe drives which will raise the speed of your Internet sites considerably. The drives work in RAID to make sure that you won't lose any data because of a power loss or a hardware malfunction. The production servers employ many different drives where the info is saved and one disk is used for parity i.e. one bit is added to all data copied on it, which makes it easier to recover the site content without any loss if a main drive fails. In case you pick our backup service, the data will be saved on a separate machine that uses standard hard-disk drives and despite the fact that there isn't a parity one in this case, they are also in a RAID to make sure that we will have a backup of your site content all the time. With this setup your information will always be safe since it will be available on many drives.
