Redundant Array of Independent Disks, or RAID, is a method of storing content on several hard disks simultaneously. A RAID might be software or hardware depending on the hard drives which are used - physical or logical ones, still what is common between them is the fact that they all operate as one single unit where info is saved. The biggest advantage of using a RAID is redundancy as the info on all of the drives is exactly the same all the time, so even in the event that some drive fails for whatever reason, the data will still be available on the rest of the drives. The overall performance is also better because the reading and writing processes will be split between various drives, so a single one will not be overloaded. There are different sorts of RAIDs where the efficiency and fault tolerance can vary according to the particular setup - whether info is written on all the drives real-time or it's written on a single drive and after that mirrored on another, what amount of drives are used for the RAID, and many others.

RAID in Web Hosting

The state-of-the-art cloud web hosting platform where all web hosting accounts are created uses fast NVMe drives instead of the standard HDDs, and they function in RAID-Z. With this configuration, multiple hard disks function together and at least a single one is a dedicated parity disk. Basically, when data is written on the rest of the drives, it is duplicated on the parity one adding an extra bit. This is carried out for redundancy as even in case some drive fails or falls out of the RAID for some reason, the info can be rebuilt and verified using the parity disk and the data stored on the other ones, therefore nothing will be lost and there will not be any service interruptions. This is one more level of security for your information along with the cutting-edge ZFS file system that uses checksums to make sure that all of the data on our servers is intact and is not silently corrupted.

RAID in Semi-dedicated Hosting

The RAID type that we use for the cloud Internet hosting platform where your semi-dedicated hosting account will be created is known as RAID-Z. What is different about it is that at least one of the disks is used as a parity drive. In simple terms, whenever any data is duplicated on this specific drive, one more bit is included to it and if a faulty disk is replaced, the info that will be duplicated on it is a combination of the data on the other drives in the RAID and that on the parity one. We do this to ensure that the information is intact. During this process, your Internet sites will be functioning normally since RAID-Z makes it possible for a whole drive to fail without service interruptions and it simply uses one of the other ones as the main production drive. Employing RAID-Z together with the ZFS file system that uses checksums to guarantee that no data will get silently corrupted on our servers, you will not need to worry about the integrity of your files.


All virtual private server accounts that our company provides are generated on physical servers that use NVMe drives functioning in RAID. At least 1 drive is intended for parity - one additional bit is included in the information copied on it and if a main disk stops working, this bit makes it much simpler to recalculate the bits of the files on the damaged drive so that the accurate info is restored on the new drive added to the RAID. In the mean time, your websites will stay online because all the info will still load from at least 1 more hard drive. If you add regular backups to your VPS package, a copy of the information will be stored on standard hard drives that also work in RAID since we want to make sure that any type of content you add will be safe and sound all the time. Employing multiple drives in RAID for all the main and backup servers allows us to offer fast and reliable Internet hosting service.
