NAS enclosure planning
Choose a bay path from its lifecycle trade-off.
Compare the drive class, raw labels, reserve-inclusive capacity, and runway required by common enclosure sizes while keeping the data forecast fixed.
Bay lifecycle comparison
Compare the enclosure path before choosing a drive class.
Hold the data forecast constant, then compare 2-, 4-, 6-, and 8-bay paths by per-drive class, raw labels, reserve-inclusive capacity, and modelled runway.
The values below are editable planning baselines. Change the few inputs you know; open Advanced assumptions only when they change your decision.
Same target, four paths
See what extra bays change before comparing products.
Drive labels are rounded up to the maintained planning classes. Layout capacity is shown before filesystem and platform overhead.
| Path | Layout boundary | Per-drive class | Layout capacity | Raw drive labels | Modelled runway |
|---|---|---|---|---|---|
| 2-bay | — | — | — | — | — |
| 4-bay | — | — | — | — | — |
| 6-bay | — | — | — | — | — |

Editorial record
Maintained by Make Your Own Tools to turn “Store data safely” into a defined capacity, bays, redundancy, and recovery baseline. The references below provide the technical context for this planning path. Its calculation rules and planning assumptions are documented in the methodology, and affected calculations pass regression checks before the review date advances.
