# Advanced RAID Calculator
|
|
|
|
|
|
|
|
A professional storage capacity planning tool for various RAID configurations, including standard RAID, Synology SHR, ZFS, and Unraid. Built by [Beyond Cloud Technology](https://www.youtube.com/@beyondcloudtechnology)..
|
|
|
|
## 🌟 Features
|
|
|
|
- **Wide RAID Support** - Calculates usable storage for:
|
|
- Standard RAID: 0, 1, 5, 6, 10
|
|
- Synology: SHR & SHR-2
|
|
- ZFS: Stripe, Mirror, RAIDZ1, RAIDZ2, RAIDZ3
|
|
- Unraid: 1 or 2 parity drives
|
|
|
|
- **Accurate Calculations** - Accounts for the difference between decimal (TB) and binary (TiB) units, showing you the actual usable capacity (e.g., 12TB drives = 10.91 TiB actual)
|
|
|
|
- **Mixed Drive Sizes** - Supports configurations with drives of different sizes, especially useful for SHR, ZFS, and Unraid
|
|
|
|
- **ZFS vdev Support** - Configure multiple vdevs within ZFS pools for advanced configurations
|
|
|
|
- **Clear Results** - Displays:
|
|
- Usable capacity (in both TiB and TB)
|
|
- Raw capacity
|
|
- Storage efficiency percentage
|
|
- Fault tolerance (how many drives can fail)
|
|
- Read/write performance insights
|
|
|
|
- **Intuitive Interface** - Easy-to-use sliders and dropdowns with real-time validation
|
|
|
|
## 📖 How to Use
|
|
|
|
### 1. Open the Calculator
|
|
|
|
Simply open the `index.html` file in any modern web browser. No installation or server required!
|
|
|
|
### 2. Select Your RAID Type
|
|
|
|
Choose your desired RAID configuration from the dropdown menu. Options are organized by category:
|
|
|
|
- **Standard RAID** - Traditional RAID levels (0, 1, 5, 6, 10)
|
|
- **Synology RAID** - SHR and SHR-2 for Synology NAS devices
|
|
- **ZFS RAID** - ZFS configurations including RAIDZ variants
|
|
- **Unraid** - Unraid parity configurations
|
|
|
|
|
|
|
|
### 3. Configure Your Drives
|
|
|
|
#### Option A: Uniform Drive Sizes
|
|
|
|
For arrays with identical drives:
|
|
1. Use the **Number of Drives** slider to set how many drives you have (2-24)
|
|
2. Select the **Drive Size (TB)** from the dropdown (1TB to 24TB)
|
|
|
|
#### Option B: Mixed Drive Sizes
|
|
|
|
For arrays with different sized drives (perfect for SHR, Unraid, or ZFS):
|
|
|
|
1. Toggle the **Mixed Drive Sizes** switch to enable custom configuration
|
|
2. Individual drive size selectors will appear for each drive
|
|
3. Set the size for each drive independently
|
|
|
|
|
|
|
|
#### Option C: ZFS with Multiple vdevs
|
|
|
|
For advanced ZFS configurations:
|
|
1. Select a ZFS RAID type (Mirror, RAIDZ1, RAIDZ2, or RAIDZ3)
|
|
2. Configure the **Number of vdevs** slider
|
|
3. Set **Drives per vdev** to determine how many drives in each vdev
|
|
4. The total drive count is calculated automatically
|
|
|
|
### 4. Calculate Storage
|
|
|
|
Click the **Calculate Storage** button to perform the calculation.
|
|
|
|
### 5. Review Results
|
|
|
|
The results panel will display comprehensive information about your configuration:
|
|
|
|
|
|
|
|
**Results include:**
|
|
- **Usable Capacity** - The actual storage available for your data (shown in both TiB and TB)
|
|
- **Raw Capacity** - Total capacity of all drives combined
|
|
- **Storage Efficiency** - Percentage of raw capacity that's usable
|
|
- **Fault Tolerance** - How many drives can fail simultaneously without data loss
|
|
- **Performance Insights** - Read and write performance characteristics
|
|
- **Drive Configuration** - Summary of your drive setup
|
|
|
|
## 💡 Understanding the Results
|
|
|
|
### Capacity Units
|
|
|
|
The calculator shows capacity in both formats:
|
|
- **TiB (Tebibytes)** - Binary units (1024-based), what your OS reports
|
|
- **TB (Terabytes)** - Decimal units (1000-based), how drives are marketed
|
|
|
|
**Example:** A 12TB drive shows as approximately 10.91 TiB in your operating system.
|
|
|
|
### Storage Efficiency
|
|
|
|
This shows what percentage of your total drive capacity is actually usable:
|
|
- **RAID 0** - 100% (no redundancy)
|
|
- **RAID 1** - 50% (full mirroring)
|
|
- **RAID 5** - Varies based on drive count: (n-1)/n
|
|
- **RAID 6** - Varies based on drive count: (n-2)/n
|
|
- **SHR/Unraid** - Optimized based on drive sizes
|
|
|
|
### Fault Tolerance
|
|
|
|
Indicates how many drives can fail before data loss:
|
|
- **0 drives** - No redundancy (RAID 0, ZFS Stripe)
|
|
- **1 drive** - Single parity (RAID 5, RAIDZ1, SHR, Unraid-1)
|
|
- **2 drives** - Double parity (RAID 6, RAIDZ2, SHR-2, Unraid-2)
|
|
- **3 drives** - Triple parity (RAIDZ3)
|
|
|
|
## 🔧 Technical Details
|
|
|
|
### Technology Stack
|

|
### Calculation Methodology
|
|
|
|
The calculator uses industry-standard formulas for each RAID type:
|
|
|
|
- **Standard RAID** - Traditional RAID calculations accounting for parity and mirroring
|
|
- **Synology SHR** - Simulates Synology's hybrid RAID algorithm for optimal space utilization
|
|
- **ZFS** - Accounts for vdev striping and RAIDZ parity overhead
|
|
- **Unraid** - Calculates based on largest drive(s) being used for parity
|
|
|
|
All calculations account for the binary/decimal conversion (TB to TiB).
