RAID, or Redundant Array of Independent Disks, is a technology of keeping data on several hard disk drives that operate together as a single logical unit. The drives could be physical or logical i.e. in the aforementioned case one drive is split into different ones using virtualization software. Either way, the very same info is stored on all drives and the main advantage of employing this kind of a setup is that in the event that a drive fails, the data will still be available on the remaining ones. Employing a RAID also enhances the overall performance since the input and output operations will be spread among a couple of drives. There are several kinds of RAID depending on how many drives are used, whether writing is done on all drives in real time or just on one, and how the information is synced between the drives - whether it's written in blocks on one drive after another or it is mirrored from one on the others. All these factors imply that the error tolerance as well as the performance between the various RAID types could differ.

RAID in Shared Web Hosting

The advanced cloud Internet hosting platform where all shared web hosting accounts are made employs fast SSD drives rather than the classic HDDs, and they work in RAID-Z. With this configuration, multiple hard disks function together and at least one is a dedicated parity disk. Simply put, when data is written on the other drives, it's duplicated on the parity one adding an extra bit. This is carried out for redundancy as even if a drive fails or falls out of the RAID for some reason, the data can be rebuilt and verified using the parity disk and the data saved on the other ones, thus not a thing will be lost and there will not 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 guarantee that all the data on our servers is intact and is not silently corrupted.

RAID in Semi-dedicated Hosting

In case you host your sites within a semi-dedicated hosting account from our company, any content you upload will be held on SSD drives which work in RAID-Z. With this form of RAID, at least 1 of the drives is used for parity - when data is synced between the hard drives, an extra bit is added to it on the parity one. The purpose behind this is to guarantee the integrity of the info which is duplicated to a new drive in case one of the hard drives in the RAID stops working since the website content being copied on the brand new disk is recalculated from the information on the standard hard drives and on the parity one. Another advantage of RAID-Z is that even in the event that a hard drive fails, the system can switch to a different one right away without service disturbances of any type. RAID-Z adds an extra level of safety for the content which you upload on our cloud web hosting platform together with the ZFS file system that uses unique checksums so as to verify the integrity of each and every file.

RAID in VPS Web Hosting

All virtual private server accounts that we offer are generated on physical servers which take advantage of SSD drives working in RAID. At least one drive is intended for parity - one additional bit is included in the info duplicated on it and if a main disk fails, this bit makes it easier to recalculate the bits of the files on the damaged hard disk so that the accurate info is recovered on the new drive added to the RAID. At the same time, your sites will stay online as all the data will still load from at least 1 other disk drive. If you add regular backups to your VPS package, a copy of your data will be saved on standard hard disks that also function in RAID because we would like to make certain that any site content you upload will be protected at all times. Working with multiple hard drives in RAID for all the main and backup servers enables us to offer fast and reliable Internet hosting service.
