I was reading about latency and IOPS, and I understood what they mean and their significance in the storage world. But what I do not understand (many places it is mentioned) is that how can the numbers actually conflict with each other when an example is given.
In this explanation, the author states one of the examples saying..
Mr. Customer, our box can do a quarter million random 4K IOPS – and not from cache!”
…at 50ms latency.
Here, if the latency in 50ms then 4K IO's should take 200s. And if really 4K IO's is being completed in 1 sec, then should'nt the average latency be 4ms?
Can someone please explain what I am missing here.
