RAID calculator is the ultimate tool to help you find your available disk space, space for data protection, and unused space with various RAID configurations. This tool uses an accurate and reliable RAID calculation formula to determine the aforementioned spaces.
Follow the given steps to use the RAID calculator.
As soon as the minimum disk count is met, the RAID calculator will quickly show you the available disk space, unused space, and space reserved for data protection.
If you are not already sold on this tool, then here are some additional features that will show you how amazing this RAID calculator is.
The RAID capacity calculator supports seven RAID configurations. These include the highly demanded RAID 5, RAID 6, and RAID 10 configurations. Here is a full list of the RAID configurations supported by our tool.
Our RAID reliability calculator comes with many convenient presets that allow new users to benefit from this tool easily. Users can choose from different hard drive sizes. Such as, 120 GB, 250 GB, 500 GB, 1 TB, etc., etc.
Coupled with the RAID configurations, it is very easy to find the storage space.
The RAID calculator works in real-time. It calculates the available space, unused space, and space allocated for security in under two seconds. Therefore, users do not have to wait to get their results.
The user interface of the RAID capacity calculator is expertly designed to aid newcomers. Simple but eye-catching graphics show the output of the RAID calculation. The various input options for RAID configuration, hard disk size, and disk size measurement units are colored differently. This makes it easy to spot and differentiate between them.
Overall, the RAID calculator is pretty easy to use due to its intuitive and simple design.
HDDs (Hard disk drives) used to be the norm until a few years ago, but now, faster technology for hard disks has emerged. Disks made with this tech are called SSDs (Solid State Drives).
Both types of drives support RAID configurations, and our RAID calculator works with them flawlessly. So, you can easily use it to calculate storage space regardless of whether you have an HDD or an SSD.
RAID stands for Redundant Array of Independent Disks. It is a hard disk configuration style that allows ample storage space for backing up your data and increases the tolerance for data loss and errors.
Different RAID configurations give differing amounts of actual storage, backup storage, and unused space. They also have different requirements for minimum hard drives.
Here’s a brief about all 7 RAID configurations used in our RAID calculator.
In RAID 0, there is no backup space. The maximum available space on the hard drives is used for data storage. RAID 0 requires a minimum of two hard drives. The data is striped (meaning written evenly) across the hard drives. This makes the data much faster to retrieve.
In RAID 1, there is no striping. Instead, Data is mirrored across two or more disks to provide redundancy. Since data can be read from any disk, the read performance is improved. RAID 1 with two disks can tolerate the failure of one disk without data loss.
In RAID 5, there are at least three drives. Aside from the standard data, there is a parity bit for each block of data. The parity bits are striped across different drives.
If one drive fails, the data on it can be reconstructed with the parity bits stored on other drives. RAID 5 has the advantage of providing more storage space than any other RAID configuration (Except RAID 0). You can confirm this with our RAID 5 calculator.
It is similar to RAID 5. The only difference is that there are two parity bits for each block of data, and the minimum number of required drives is four instead of three.
RAID 10 is actually RAID 1+0. In this configuration, you have two RAID 1 configurations under a RAID 0 configuration. This is known as a Nested RAID configuration.
In RAID 10, data is both mirrored and striped. This way, you get faster performance and data protection. You need a minimum of 4 drives for RAID 10.
Otherwise known as RAID 5+0, in this configuration, RAID 5 is combined with RAID 0. As a result, you get RAID 5 parity with RAID 0 striping, which results in faster RAID 5 performance. You need at least six drives for RAID 50.
Also known as RAID 6+0, the data is striped across two RAID 6 configurations. It requires a minimum of eight drives.
You can add multiple disk spaces by simply clicking on one of the given storage size options. The RAID reliability calculator will automatically add the clicked option to the list of drives for calculation.
Yes, our RAID calculator will clearly list whether a particular RAID configuration has fault tolerance or not. If you check the RAID 5 configuration, you will find that it does have a high fault tolerance.
The RAID calculator is completely free to use and does not require you to create an account either. The number of uses is also unlimited, so you do not have to worry about usage restrictions.
