Redundant Array of Independent Disks, or RAID, is a way of saving content on multiple hard drives at the same time. A RAID could be software or hardware based on the HDDs that are used - physical or logical ones, but what is common between them is the fact that they all work as just one single unit where your information is stored. The key advantage of using a RAID is redundancy because the data on all the drives is identical at all times, so even if one of the drives fails for whatever reason, the information will still be present on the rest of the drives. The general performance is enhanced as well since the reading and writing processes will be split between various drives, so a single one will never be overloaded. There're different types of RAIDs where the functionality and fault tolerance could differ according to the specific setup - whether info is written on all drives real-time or it is written on a single drive and afterwards mirrored on another, what amount of drives are used for the RAID, etc.

RAID in Shared Web Hosting

The hard disks that we use for storage with our revolutionary cloud web hosting platform are not the standard HDDs, but high-speed solid-state drives (SSD). They operate in RAID-Z - a special setup developed for the ZFS file system that we employ. All of the content that you upload to the shared web hosting account will be saved on multiple hard disks and at least 1 shall be used as a parity disk. This is a special drive where an extra bit is included to any content copied on it. In the event that a disk in the RAID stops working, it will be replaced without service interruptions and the info will be recovered on the new drive by recalculating its bits thanks to the data on the parity disk along with that on the remaining disks. This is done so as to guarantee the integrity of the information and together with the real-time checksum verification that the ZFS file system runs on all drives, you won't ever need to concern yourself with losing any data no matter what.

RAID in Semi-dedicated Hosting

In case you host your sites inside a semi-dedicated hosting account from our firm, any content that you upload will be kept on SSD drives which operate in RAID-Z. With this type of RAID, at least one of the hard drives is employed for parity - when data is synced between the disks, an additional bit is added to it on the parity one. The reasoning behind this is to guarantee the integrity of the information which is duplicated to a new drive if one of the drives in the RAID stops working as the content being copied on the new disk is recalculated from the information on the standard disk drives and on the parity one. An additional advantage of RAID-Z is the fact that even in case a hard drive fails, the system can easily switch to a different one right away without service disturbances of any sort. RAID-Z adds an extra level of security for the content you upload on our cloud web hosting platform along with the ZFS file system which uses unique checksums as a way to authenticate the integrity of every single file.

RAID in VPS Hosting

In case you employ one of our virtual private server solutions, any content that you upload will be stored on SSD drives that function in RAID. At least a single drive is employed for parity so as to ensure the integrity of the data. In simple terms, this is a special drive where info is copied with one bit added to it. In case a disk in the RAID breaks down, your Internet sites will continue working and when a new disk takes the place of the flawed one, the bits of the info that will be copied on it are calculated by using the healthy and the parity drives. By doing this, any probability of corrupting data during the process is prevented. We also use ordinary hard drives which function in RAID for storing backup copies, so should you add this service to your VPS package, your content will be stored on multiple drives and you won't ever have to worry about its integrity even in the event of multiple drive breakdowns.
