It won't be a real life test and 4KB is rather small by today's standards, 8KB is about the smallest there is for the typical database (Oracle, MS-SQL) on top of this, there is a *lot* of sequential writes.
(there are of course other workloads besides databases but they will most likely have a much larger block size)

I'll make some options on how to write, 4KB, 8KB, ..., as well as more options on size. (including full span)

This type of test is highly unlikely in any environment though.

We already know what Intel data-sheets tells.

100% 4KB writes, 100% span.
