DISK Tools

RAID capacity and rebuild time, storage unit conversion, space usage and IOPS estimates.

raid calculator

Select RAID level to calculate capacity and performance characteristics
Enter the number of physical disks in the RAID array
Enter the capacity of each disk in terabytes
Typical: 50-150 MB/s
Common: 64, 128, 256

RAID 5 - Distributed Parity
  • Minimum disks: 3
  • Can survive 1 disk failure
  • Good read performance
  • Write performance penalty due to parity
  • Capacity: (N-1) × disk size

disk space calculator

Enter numeric value to convert between storage units
Select source unit for conversion
