RAID Performance Calculator

Estimate read and write performance for different RAID configurations based on disk specifications.

Select the RAID level for your configuration

Enter the number of disks in your RAID array

Enter the read/write speed of a single disk in MB/s

RAID Performance Characteristics

RAID 0

Maximum performance with no redundancy. Read and write speeds scale with the number of disks.

RAID 1

Good read performance with write performance similar to a single disk. Provides redundancy.

RAID 5/6

Good read performance with moderate write performance. Provides redundancy with parity.

Quick Examples

RAID 0 with 4 Disks

  • Disk Speed: 200 MB/s
  • Read Speed: 800 MB/s
  • Write Speed: 800 MB/s

RAID 5 with 6 Disks

  • Disk Speed: 200 MB/s
  • Read Speed: 1000 MB/s
  • Write Speed: 400 MB/s
