How This Calculator Works

Purpose and Design

This RAID calculator is designed to help Synology NAS users, IT professionals, and storage enthusiasts plan their storage configurations. It extends the capabilities of the official Synology RAID calculator by supporting larger disk sizes, up to 30TB.

Key Features

• Supports various RAID types: SHR, SHR-2, RAID 0, 1, 5, 6, and 10
• Calculates available capacity, space used for data protection, and unused space
• Allows for mixing different drive sizes
• Provides results for all RAID types simultaneously for easy comparison
• Supports drive sizes from 1TB to 30TB

Understanding the Results

Note: The "Used for Protection" column shows the amount of storage space dedicated to data protection in each RAID configuration. This is not a measure of the level of protection, but rather the capacity used to achieve the protection for that RAID type.

Who Can Benefit

This tool is particularly useful for:

• Users planning to upgrade their Synology NAS with larger drives
• IT administrators designing storage solutions for high-capacity needs
• Anyone looking to understand the trade-offs between different RAID configurations
• Those exploring configurations with the latest high-capacity drives (up to 30TB)

How to Use

Simply add the drives you're considering, and the calculator will instantly show you the results for all supported RAID types, even for configurations with the largest available drives on the market.
