RAID, or Redundant Array of Independent Disks, is a technology of keeping data on multiple hard disks which work together as one single logical unit. The drives could be physical or logical i.e. in the aforementioned case one single drive is divided into independent ones through virtualization software. Either way, exactly the same information is kept on all the drives and the key benefit of employing this type of a setup is that if a drive fails, the data will still be available on the remaining ones. Employing a RAID also boosts the performance since the input and output operations will be spread among several drives. There are several types of RAID depending on how many hard drives are used, whether writing is performed on all drives in real time or just on a single one, and how the information is synchronized between the hard drives - whether it's written in blocks on one drive after another or it is mirrored from one on the others. These factors show that the error tolerance and the performance between the different RAID types could differ.

RAID in Cloud Hosting

The advanced cloud Internet hosting platform where all cloud hosting accounts are generated uses quick SSD drives instead of the traditional HDDs, and they function in RAID-Z. With this configuration, a number of hard disk drives function together and at least one of them is a dedicated parity disk. Simply put, when data is written on the other drives, it is 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 information can be rebuilt and verified thanks to the parity disk and the data saved on the other ones, therefore practically nothing will be lost and there will not be any service disorders. This is an additional level of security for your info together with the state-of-the-art ZFS file system which uses checksums to make sure that all data on our servers is intact and is not silently corrupted.

RAID in Semi-dedicated Hosting

The RAID type that we employ for the cloud hosting platform where your semi-dedicated hosting account will be created is referred to as RAID-Z. What's different about it is that at least 1 of the disks is employed as a parity drive. Put simply, whenever any kind of data is duplicated on this particular drive, one more bit is included to it and in the event that a defective disk is replaced, the info which will be cloned on it is a combination of the data on the remaining disk drives in the RAID and that on the parity one. We do this to make sure that the data is intact. Throughout this process, your sites will be functioning normally as RAID-Z enables a whole drive to fail without any service disturbances 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 ensure that no data shall get silently corrupted on our servers, you will not have to worry about the integrity of your files.


The physical servers where we generate virtual private server employ super fast SSD drives which will increase the speed of your sites noticeably. The drives work in RAID to make sure that you won't lose any information because of a power loss or a hardware breakdown. The production servers employ multiple drives where the data is kept and one disk is used for parity i.e. one bit is added to all of the information copied on it, that makes it easier to restore the site content without loss if a main drive breaks down. If you choose our backup service, your information will be stored on an individual machine that uses standard hard-disk drives and although there is no parity one in this case, they are also in a RAID to ensure that we will have a backup of your content all the time. With this particular setup your data will always be safe as it will be available on several drives.
