What are IOPS and Should You Care


What are IOPS and Should You Care?

When evaluating a new storage system, especially an all-flash array, the number of IOPS (Inputs/ Outputs per Second) that the storage system can sustain is often used to differentiate one storage system from another. But is this really a standard that has any merit given the demands of today’s data center and the capabilities of today’s storage systems?

There are three factors that when combined tell the full story of storage performance:

  1. Bandwidth rate
  2. Latency
  3. IOPS

Most storage vendors tend to focus on IOPS to brag about how fast their storage system is. But measuring storage system performance by IOPS only has value if the workloads using that storage system are IOPS demanding. Read the full report from George Crump at Storage Switzerland to learn more
