So berechnen Sie Storage RAID

learn.whatIsHeading

RAID calculator determines data protection level, usable capacity, and redundancy. Different RAID levels offer various tradeoffs between speed, capacity, and fault tolerance.

Formel

RAID 0: Capacity = n×D; RAID 1: Capacity = D; RAID 5: Capacity = (n-1)×D; etc.

Schritt-für-Schritt-Anleitung

1Enter number of drives and drive capacity
2Select RAID level
3Calculate usable capacity and fault tolerance

Gelöste Beispiele

Eingabe

4 drives × 2TB each, RAID 5

Ergebnis

Usable: 6TB, Can lose 1 drive

RAID 5 parity stripe

Häufige Fehler vermeiden

✕Confusing hot spare with usable drives
✕Not accounting for RAID rebuild time vulnerability
