How can I calculate approximate expected IOPS once I have measured or estimated the IOPS for a drive?

For reads RAID 10 will give 100% of the read IOPS for all the drives, so for 4 disks with 210 IOPS, you would get 840 read IOPS.

For writes RAID 10 will give you 50% of the write IOPS for all the drives, so for 4 disks with 210 IOPS, you would get 420 write IOPS.

Just to correct math write performance would be 420 IOPs. These numbers are ballpark but a good illustration. Thanks, Dart!
