How much space will you actually get? RAID Calculator answers in seconds, for identical drives in classic RAID and for the mixed drives in a real NAS, whether it runs Synology, Unraid, ZFS, SnapRAID or Btrfs. PLAN YOUR NEXT DRIVE Real NAS boxes rarely hold identical drives. Give each bay its own size, or leave it empty, and see what your system does with them: • Five systems: Synology SHR, SHR-2 and RAID 1, 5 or 6; Unraid; ZFS RAID-Z; SnapRAID; and Btrfs RAID1 • Every drive drawn to scale and split into what it holds: data, parity, a mirror copy, or nothing at all • Unused capacity hatched, with the number spelled out • Biggest Upgrade names the single purchase that unlocks the most space, with one tap to try it • Save your current setup, then see every change compared with it (“+4 TB usable”), and Revert when you’re done • Unraid and SnapRAID put parity on your largest drives automatically • For ZFS, the figure ZFS itself will report, labeled as an estimate • Advice where it matters: SnapRAID’s recommended parity count, and a note on very wide RAID-Z groups • From 2 to 12 bays for Synology, or up to 30 for Unraid, ZFS, SnapRAID and Btrfs RAID1 COMPARE SYSTEMS See your drives under every system at once, most usable space first, with failures tolerated and unused space for each. Tap a system to switch to it and watch the same bays re-split. CLASSIC RAID, INSTANTLY Pick RAID 0, 1, 5, 6, 10, 50 or 60, JBOD, or ZFS RAID-Z1, Z2 or Z3, set from 1 to 24 drives and their size, and the answer is the first thing you see: • Usable capacity, raw capacity and storage efficiency • A drive strip showing which drives hold data, parity or mirror copies, split into groups for nested levels and RAID-Z • How many drives can fail, honest about the cases that depend on which drives fail • The TiB figure most NAS systems will report, and for RAID-Z what ZFS itself will report • A rebuild-risk caution for single-parity layouts on large drives, with a one-tap switch to a safer level when your drives allow it • Invalid setups explain themselves and offer a one-tap fix • Relative speed and availability ratings for every level LEARN AS YOU GO Every RAID level and every NAS system has an info sheet: an overview, pros and cons, and typical uses, plus ratings for RAID levels. RAID-Z and every NAS system also explain how the app calculates them. ON EVERY SCREEN • On iPad, and on iPhone Duo opened in landscape, results sit beside inputs and systems line up side by side • On iPad, up to 30 bays fit on screen • On iPhone Duo, info opens in place of the inputs so the results stay in view • Rotates to landscape on iPhone • Built for iOS 26 with native controls and Liquid Glass • Dark mode, Dynamic Type at every size, and full VoiceOver support that also reads each drive within a group • English, Spanish, French, Italian, Japanese, German, Traditional and Simplified Chinese, Korean, Brazilian Portuguese and Russian PRIVATE BY DESIGN No account, no ads, no tracking, no network connection needed. Every calculation happens on your device. Capacities use standard simplified formulas and don’t account for filesystem overhead, apart from the labeled ZFS estimate. Speed and availability ratings compare RAID levels with each other; they aren’t benchmarks. Not affiliated with or endorsed by Synology Inc. Synology and SHR are trademarks of Synology Inc.
