  • Input/Output Operations Per Second, a common benchmark for harddisks and other computer storage media.
  • International Organisation of Pension Supervisors, an independent international body representing those involved in the supervision of private pension arrangements.


Sorry, no etymologies found.


  • How will an order of magnitude improvement in IOPS change the art of the possible in customer-facing applications?

    The Solid-State Future

  • For example, SanDisk showed the 240GB drive performing around 450 4KB random write IOPS, which is some 6x faster than traditional hard drives, according to the company. : News

  • Multiply that by 16, and you get 2,880,000 IOPS which is 500,000 less than the 2.3 million predicted by Oakgate.

    The Register

  • Initial tests show a sustained throughput rate of 100,000 IOPS which is staggering considering that this is just a simple 4 core, nothing special server.

    Data Center Knowledge

  • Extreme Throughput -- many cloud storage providers shy away from high performance database storage altogether because of an inability to hit IOPS targets.

    Tony Greenberg: Key Cloud Migration Decisions

  • Just as with the last storage discontinuity, total cost per IOPS will be much lower for SSDs relative to hard disks in many, if not most, cases.

    The Solid-State Future

  • Solid-state disks will help us regain the balance between storage and compute, so CAPEX per IOPS may well decrease substantially.

    The Solid-State Future

  • With 64 bit address spaces, why even have IOPS for persistent storage?

    The Solid-State Future

  • Power consumption is lower with SSDs than with hard disks, so electricity costs per IOPS will also drop.

    The Solid-State Future

  • Delivering results to a search query, placing the right advertisement in front of the right consumer at the right time, running a massively multiplayer online game, and building personalized pages are IOPS-intensive applications operating on gargantuan data stores.
