Redundant Array of Independent Disks, or RAID, is a way of storing content on multiple hard disk drives at the same time. A RAID can be software or hardware depending on the hard drives which are used - physical or logical ones, but what is common between them is that they all function as a single unit where your information is kept. The key advantage of employing a RAID is redundancy as the info on all of the drives is identical at all times, so even in case some drive fails for whatever reason, the info will still be present on the rest of the drives. The overall performance is also enhanced since the reading and writing processes could be split between multiple drives, so a single one will not be overloaded. There are different sorts of RAIDs where the functionality and fault tolerance can vary according to the particular setup - whether data is written on all the drives in real time or it's written on one drive and afterwards mirrored on another, what amount of drives are used for the RAID, etcetera.

RAID in Shared Hosting

The revolutionary cloud Internet hosting platform where all shared hosting accounts are made uses quick SSD drives as an alternative to the classic HDDs, and they function in RAID-Z. With this configuration, multiple hard disks function together and at least 1 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 if some drive fails or falls out of the RAID for whatever reason, the information can be rebuilt and verified using the parity disk and the data saved on the other ones, thus practically nothing will be lost and there will be no service interruptions. This is one more level of security for your data in addition to the state-of-the-art ZFS file system that uses checksums to make sure that all the data on our servers is intact and is not silently corrupted.

RAID in Semi-dedicated Hosting

The RAID type which we use for the cloud web hosting platform where your semi-dedicated hosting account shall be created is named RAID-Z. What is different about it is that at least one of the disks is used as a parity drive. Put simply, whenever any data is copied on this particular hard drive, one more bit is included to it and if a defective disk is replaced, the information which will be cloned on it is a mix of the data on the other hard disks in the RAID and that on the parity one. We do this to guarantee that the info is intact. During this process, your websites will be functioning normally as RAID-Z makes it possible for a whole drive to fail without any service interruptions and it simply works by using one of the other ones as the main production drive. Employing RAID-Z together with the ZFS file system which uses checksums to warrant that no data can get silently corrupted on our servers, you will never have to worry about the integrity of your files.


All virtual private server accounts that we offer are created on physical servers that take advantage of SSD drives working in RAID. At least 1 drive is used for parity - one additional bit is added to the information copied on it and in case a main disk stops working, this bit makes it much simpler to recalculate the bits of the files on the damaged disk drive so that the correct information is restored on the new drive included in the RAID. Meanwhile, your sites will still be online as all the information will still load from at least one other hard disk. In the event that you add routine backups to your VPS package, a copy of your info will be kept on standard hard disks which also work in RAID since we want to make certain that any type of content you upload will be safe and sound at all times. Working with multiple hard drives in RAID for all main and backup servers permits us to offer fast and reliable Internet hosting service.
