RAID, or Redundant Array of Independent Disks, is a technology for keeping data on multiple hard drives which work together as a single logical unit. The drives could be physical or logical i.e. in the second case one single drive is split into separate ones using virtualization software. In any case, identical info is saved on all the drives and the main advantage of employing this kind of a setup is that in case a drive stops working, the data will still be available on the remaining ones. Having a RAID also enhances the performance as the input and output operations will be spread among several drives. There are several types of RAID based on how many drives are used, whether writing is performed on all of the drives in real time or just on one, and how the info is synchronized between the hard drives - whether it is recorded in blocks on one drive after another or all of it is mirrored from one on the others. All of these factors indicate that the error tolerance and the performance between the various RAID types may differ.

RAID in Cloud Hosting

Our advanced cloud Internet hosting platform where all cloud hosting accounts are created uses quick NVMe drives as opposed to the classic HDDs, and they work in RAID-Z. With this setup, multiple hard disks work together and at least one is a dedicated parity disk. Put simply, when data is written on the other drives, it is duplicated on the parity one adding an extra bit. This is carried out for redundancy as even if 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 saved on the other ones, therefore absolutely nothing will be lost and there won't be any service interruptions. This is another level of protection for your information in addition to the cutting-edge ZFS file system which uses checksums to guarantee that all of the data on our servers is undamaged and is not silently corrupted.

RAID in Semi-dedicated Hosting

In case you host your Internet sites within a semi-dedicated hosting account from our company, any content that you upload will be held on NVMe drives which work in RAID-Z. With this kind of RAID, at least one of the hard disks is employed for parity - when data is synchronized between the disks, an extra bit is added to it on the parity one. The purpose behind this is to guarantee the integrity of the data that is copied to a brand new drive in case one of the drives in the RAID fails as the content being copied on the new disk is recalculated from the data on the standard drives and on the parity one. An additional advantage of RAID-Z is that even in the event that a drive fails, the system can easily switch to a different one right away without service disturbances of any type. RAID-Z adds an additional level of security for the content you upload on our cloud hosting platform in addition to the ZFS file system that uses unique checksums as a way to authenticate the integrity of each file.

RAID in VPS Web Hosting

All virtual private server accounts that we provide are created on physical servers which employ NVMe drives working in RAID. At least one drive is employed for parity - one extra bit is included in the data duplicated on it and if a main disk stops working, this bit makes it simpler to recalculate the bits of the files on the failed drive so that the accurate information is restored on the new drive included in the RAID. At the same time, your Internet sites will remain online since all the information will still load from at least 1 more drive. If you add regular backups to your VPS plan, a copy of your info will be saved on standard hard drives that also work in RAID because we want to make sure that any sort of website content you upload will be protected all of the time. Working with multiple drives in RAID for all of the main and backup servers permits us to offer fast and reliable hosting service.
