Use the result to make the next technical decision.
Estimate mirror, single-parity, double-parity and triple-parity capacity and see the impact of spares and operational headroom.
Storage planning
Estimate usable array capacity before buying the drives.
Model mirrors or parity layouts, remove hot spares and reserve operational free space so raw drive totals do not become a capacity surprise.

Planning values
Read observations in context.
Real ZFS capacity also depends on device size, ashift, metadata, recordsize, compression, slop space and parity geometry. This is planning arithmetic, not zpool output.
Marketing analytics never receive the target.
DotMoose records only the tool name and a coarse success/error outcome for marketing analytics. Active server diagnostics use bounded operational security logs without placing the entered domain, IP, URL, DNS answer or report contents into marketing telemetry.
