IOPS

“IOPS” stands for “Input/Output Operations Per Second.” IOPS is an important performance metric for storage devices that shows number of read/write operations that a storage device can perform per second.

A high IOPS number means that a storage device is capable of performing a large number of read and write operations in a very short amount of time. This can be beneficial for applications and systems that require fast and efficient access to storage resources.

If there is a sudden drop in IOPS, it could indicate a problem with the storage system or with one of the applications running on the system.
