Thanks Josh for an excellent series of posts, they have been most informative. Do I understand correctly that this ideal physical limit to IOPS applies when all I/O operations take place only on single sectors of the hard drive?

Any I/O greater than 512 bytes will mean additional seek time to complete that operation, as the heads will need to be repositioned. One would then also consider the transfer rate limitations of the storage unit

Josh – As a SMB VMware customer, this series really helped fill in some gaps in my understanding of storage.

The Yellow Bricks article was helpful too. Please keep up the great work!

Craig – good observation. Block size/workload characterization comes in the next installment as I move from the basics into real-world scenarios. Thanks for reading! -Josh

You miss out something regarding the block size and behavior which will significant impact the IOPS from time to time. Just my 2 cents
