You must average both write and write seek times in order to find the average seek time. Most of these ratings are given to you by the manufacturers. Generally a HDD will have an IOPS range of 55-180, while a SSD will have an IOPS from 3,000 – 40,000.

Are more IOPS better?

The greater the number of IOPS, the better the performance. How long it takes for a storage device to start an IO task, or latency, is measured in fractions of a second. The smaller the latency time is the better.

Should IOPS be high or low?

Higher values mean a device is capable of handling more operations per second. For example, a high sequential write IOPS value would be helpful when copying a large number of files from another drive. SSDs have significantly higher IOPS valued than HDDs.
