RAID-Rechner.
Berechnen Sie Nutzkapazität, Effizienz, Ausfalltoleranz, IOPS, Durchsatz und Rebuild-Zeit für RAID 0, 1, 5, 6, 10, 50, 60 und ZFS RAIDZ.
Hard drives under production load often rebuild at 50–150 MB/s.

| JBOD / span (no redundancy) | 128 TB | 100 % | 0 | 150 |
- RAID protects against drive failure, not deletion, ransomware, fire or controller faults. Keep separate backups.
- Drive makers use decimal terabytes (10¹² bytes); operating systems often show binary TiB.

Technische Hinweise auf Englisch
Assumes identical drives. ZFS padding and slop space, controller caches and filesystem overhead are not included. RAID is not a backup. Everything is calculated in your browser; nothing is sent or probed on the network.
Usable capacity = data drives × size. Mixed IOPS = raw IOPS × read % + raw IOPS × write % ÷ write penalty. A RAIDZ vdev delivers about one drive’s random IOPS. Rebuild time = drive size ÷ rebuild speed.
8 × 16 TB drives in RAID 6 give 96 TB (87.3 TiB) usable, survive 2 drive failures and rebuild one drive in about 44 hours at 100 MB/s.
