Redundant Array of Independent Disks, or RAID, is a method of keeping content on several hard drives at the same time. A RAID can be software or hardware based on the hard drives which are used - physical or logical ones, however what’s common between them is the fact that they all work as one single unit where your information is stored. The main advantage of employing a RAID is redundancy since the information on all of the drives is exactly the same at all times, so even if one of the drives fails for some reason, the information will still be available on the remaining drives. The overall performance is also better because the reading and writing processes will be split between a number of drives, so a single one can't be overloaded. There are different kinds of RAIDs where the performance and fault tolerance may differ according to the exact setup - whether your data is written on all the drives real-time or it's written on a single drive and after that mirrored on another, the number of drives are used for the RAID, and so on.

RAID in Shared Website Hosting

All content which you upload to your new shared website hosting account will be stored on quick SSD drives which work in RAID-Z. This setup is built to use the ZFS file system which runs on our cloud web hosting platform and it adds another level of protection for your site content on top of the real-time checksum validation which ZFS uses to ensure the integrity of the data. With RAID-Z, the data is stored on several disks and at least one of them is a parity disk - whenever information is written on it, an extra bit is added, so in case any drive stops functioning for whatever reason, the integrity of the info can be verified by recalculating its bits in accordance with what is saved on the production disks and on the parity one. With RAID-Z, the functioning of our system will not be interrupted and it'll continue working smoothly until the faulty drive is replaced and the information is synced on it.

RAID in Semi-dedicated Hosting

In case you host your sites in a semi-dedicated hosting account from our company, any content that you upload will be kept on SSD drives which work in RAID-Z. With this form of RAID, at least 1 of the hard drives is employed for parity - when data is synced between the drives, an additional bit is added to it on the parity one. The reasoning behind this is to guarantee the integrity of the information that is duplicated to a new drive in the event that one of the hard drives in the RAID breaks down as the site content being copied on the new disk is recalculated from the data on the standard hard drives and on the parity one. Another advantage of RAID-Z is the fact that even in the event that a drive fails, the system could switch to another one immediately without service disturbances of any sort. RAID-Z adds one more level of security for the content which you upload on our cloud hosting platform together with the ZFS file system which uses unique checksums to validate the integrity of each file.

RAID in VPS Web Hosting

If you take advantage of one of our virtual private server packages, any content which you upload will be stored on SSD drives that operate in RAID. At least a single drive is intended for parity to ensure the integrity of the info. In simple terms, this is a special drive where data is copied with one bit added to it. In the event that a disk within the RAID stops functioning, your websites will continue working and when a new disk replaces the flawed one, the bits of the data that will be duplicated on it are calculated using the healthy and the parity drives. By doing this, any probability of corrupting data throughout the process is averted. We also employ ordinary hard disks that function in RAID for storing backup copies, so if you include this service to your VPS package, your website content will be stored on multiple drives and you'll never have to worry about its integrity even in the event of multiple drive breakdowns.
