How this shelf helps

Use these tools to plan RAID arrays, NAS capacity, video recording storage, memory cards, download time, VRAM, cabling, RF links, and hardware capacity before buying drives or configuring systems.

Calculator groups

Disk RAID CalculatorCalculate usable RAID capacity from drive count, drive size, RAID level, hot spares, filesystem overhead, and decimal-vsRAID 5 CalculatorEstimate RAID 5 capacity from drive count, drive size, hot spares, and filesystem overhead. RAID 5 is space-efficient, bRAID 6 CalculatorEstimate RAID 6 usable capacity and dual-parity overhead. RAID 6 gives up more capacity than RAID 5 but can survive two RAID 10 CalculatorEstimate RAID 10 capacity for mirrored stripe sets. RAID 10 usually sacrifices half of raw capacity but offers simple reMixed Drive RAID CalculatorEstimate what happens when a RAID array contains different drive sizes. Generic RAID usually treats each disk as if it wNAS Capacity CalculatorEstimate whether a NAS configuration meets your target usable capacity after RAID choice, hot spares, and a planning oveSurveillance Storage CalculatorEstimate security camera storage from camera count, bitrate, FPS, recording hours, retention days, compression, and motiCCTV Storage CalculatorEstimate security camera storage from camera count, bitrate, FPS, recording hours, retention days, compression, and motiMemory Card CalculatorEstimate how many photos or how much video a memory card can hold using card size, average file size, video bitrate, andDownload Time CalculatorEstimate download or upload time from file size, connection speed, unit choice, and real-world overhead.Memory Timing CalculatorConvert DDR data rate and timing values into true latency in nanoseconds so memory kits can be compared more fairly.Cable CalculatorEstimate cable voltage drop from voltage, current, one-way length, wire gauge, material, and phase. This is a safety-senVRAM CalculatorEstimate VRAM needs for gaming, creator work, multi-monitor setups, and rough local AI workloads using resolution, qualiRF Path CalculatorThis technical calculator uses visible units and deterministic formulas to estimate capacity, transfer time, latency, orWindows Storage Spaces CalculatorThis technical calculator uses visible units and deterministic formulas to estimate capacity, transfer time, latency, orLinux Chmod CalculatorThis technical calculator uses visible units and deterministic formulas to estimate capacity, transfer time, latency, or

Methodology notes

  • Exact formulas show the key equation and a numeric example.
  • Estimate tools use visible assumptions, ranges, and disclaimers.
  • Safety-sensitive calculators are conservative and may stay noindex until reviewed.
  • Draft or underdeveloped shelves do not appear in the sitemap.
