Redundant Array of Independent Disks, or RAID, is a method of keeping content on a number of hard disks at the same time. A RAID might be software or hardware based on the HDDs that are used - physical or logical ones, however what is common between them is the fact that they all work as a single unit where info is saved. The biggest advantage of using a RAID is redundancy because the data on all of the drives will be exactly the same all the time, so even if a drive fails for some reason, the data will still be available on the remaining drives. The general performance is also enhanced because the reading and writing processes can be split between various drives, so a single one can't be overloaded. There're different kinds of RAIDs where the efficiency and fault tolerance may vary based on the particular setup - whether your data is written on all of the drives real-time or it's written on a single drive and then mirrored on another, what number of drives are used for the RAID, and so on.

RAID in Cloud Hosting

Our cutting-edge cloud web hosting platform where all cloud hosting accounts are generated uses super fast SSD drives as opposed to the traditional HDDs, and they work in RAID-Z. With this setup, numerous hard disks work together and at least 1 is a dedicated parity disk. In simple terms, when data is written on the rest of the drives, it's duplicated on the parity one adding an extra bit. This is done for redundancy as even in case some drive fails or falls out of the RAID for some reason, the data can be rebuilt and verified thanks to the parity disk and the data recorded on the other ones, thus nothing will be lost and there won't be any service disorders. This is another level of protection for your data together with the cutting-edge ZFS file system which uses checksums to make sure that all data on our servers is undamaged and is not silently corrupted.

RAID in Semi-dedicated Servers

If you host your websites inside a semi-dedicated server account from our firm, any content which you upload will be stored on SSD drives which work in RAID-Z. With this type of RAID, at least 1 of the hard drives is used for parity - when data is synced between the hard drives, an additional bit is added to it on the parity one. The reasoning behind this is to ensure the integrity of the data which is cloned to a brand new drive in the event that one of the disks in the RAID fails because the content being copied on the brand new disk is recalculated from the info on the standard drives and on the parity one. An additional advantage of RAID-Z is the fact that even in the event that a drive stops functioning, the system can switch to another one immediately without service interruptions of any kind. RAID-Z adds an additional level of protection for the content you upload on our cloud Internet hosting platform in addition to the ZFS file system which uses unique checksums as a way to authenticate the integrity of every single file.

RAID in VPS Servers

The physical servers where we create VPS server work with extremely fast SSD drives that will raise the speed of your websites significantly. The hard disks function in RAID to guarantee that you won't lose any data as a result of a power loss or a hardware failure. The production servers use a variety of drives where the info is saved and one disk is used for parity i.e. one bit is added to all of the info copied on it, that makes it easier to recover the content without any loss if a main drive stops working. In case you take advantage of our backup service, your data will be saved on a separate machine that uses standard hard-disk drives and although there's no parity one in this case, they are also in a RAID to ensure that we will have a backup of your site content all the time. With this kind of setup your information will always be safe since it will be available on multiple drives.
