RAID Calculator

RAID Calculator is a simple application that is built for estimating the real size of a RAID disk based on the used RAID levels. This enables you to decide which scheme provides you the desired disk space for your configuration.
The RAID technology is widely used for improving the data performance and security for both servers and personal computers. Although the technology implies combining multiple physical hard drives into a single logical unit, there are several configurations that can be used.
While some of them are designed to provide you with maximum disk space (RAID 0), others aim to improve data reading performance by storing similar data on multiple disks. You have the option to select the scheme that best suits your purpose and optimizes the available storage.
The RAID Calculator allows you to quickly estimate the available disk space when you combine several hard disks and use a certain RAID level. All you need to do is specify the number of drives, disk size and RAID configuration.
If you need to create a RAID disk, RAID Calculator provides you with a calculation tool capable of generating quick results. However, most users need to know a lot more about each RAID level before they make an informed decision.
Although the program does not include any documentation, it provides you with a link to the RAID technology on Wikipedia in order to read more details. If you have not done your research before, this can help you get started.
Unfortunately, you do not have the option to compare results for different scenarios or view the improvements such as the speed gain or the fault tolerance.
Overall, the RAID Calculator is a simple calculation tool that includes most of the used RAID configurations and provides accurate results.
