RAID Capacity Calculator

This RAID calculator computes array characteristics based on the the RAID level, the number of disks, and the disk capacity. Supported RAID levels are RAID 0, RAID 1, RAID 4, RAID 5, RAID 6, RAID 10 (1+0), RAID-DP, ZFS RAIDs (RAID-Z1, RAID-Z2, RAID-Z3).

RAID Type:
Disk Size (GB): 
Number of Disks: 


RAID Type: RAID0 (Stripe set)

Size (GB) = 146
Number of disks = 2
Space efficiency = 1 (100%)
Fault tolerance = 0 disk(s) (none)
RAID IO penalty (read) = 1/1 (one RAID IO per each host IO)
RAID IO penalty (write) = 1/1 (one RAID IO per each host IO)

Notes:
Minimum number of disks = 2.
RAID0 is not recommended for data with any business value.
