RAID iOPS Calculator - iOPS Required for Array Workload

To calculate the iOPS required by an array supporing a given read/write workload, enter the total iOPS needed, the read workload (which will provide the write workload), and the RAID level being used (so IO penalty can be accounted for). Then, click the Calculate Usable RAID Capacity button.


RAID I/O Penalties

RAID Level Read Write
RAID 0 1 1
RAID 1 1 2
RAID 5 1 4
RAID 6 1 6
RAID 10 1 2

Calculations used for this iOPS calculator are based upon the two great resources, TechRepublic's Calculate IOPS in a stoage array and Yellow Bricks' article entitled IOPS?
