    Same concept as above but from a different perspective:
    There are 1024 KB in a MB so you would convert the 10MBps to KB (the block size). Then divide the result by the block size being used (64).

    1024*10=10240
    10340/64=160

    Hi, I have to solve this problem:
    The system, that operates with 64KB blocks has 1,000 heavy users at a peak of 2 IOPS each and 2,000
    typical users at a peak of 1 IOPS each with a read/write ratio of 2:1. It is
    estimated that the application also experiences an overhead of 20 percent
    for other workloads. Heavy users have 400 GB and typical users have 75 Gb of unique data in this system. Calculate the IOPS requirements for RAID 1,
    RAID 5, and RAID 6. Is it the same? Those 64 KB, 4000 GB and 75 GB are confusing.
