Sorry? 900 VMs equals 100% full random access. There is no sequential access there, just as I said in my first comment.

> It is obvious there is a difference

Because of your comment[0].

This comment[1] pretty much summarized what I said in a more eloquent way.

it depends on workload, if they do most of the work in RAM, and most of fs traffic is snapshoting and restoring from snapshots, then you will get 99% io seq traffic. If they do some non-trivial fs operations, then you will get q16t16 io traffic. It is very unlikely you will get q1t1 random.

In my view you are jumping from topic (single ssd vs nas) to another topic (your speculations about benchmark not representing real world scenarios) and then back.
