This is not exactly what you said as we can see here: And this is just not the case as 4Kn (advanced 4Kn format) can only work with ashift=12 as they don't have emulation for 512bytes as opposed to the 512e (advanced format drives) which have 4K physical sectors, report 512b logical sectors...

Well that's a pretty good answer to my question :) Very much appreciated Gea for laying it down that way! I was seeing things the same, I guess I just wanted another confirmation that ZFS would utilize 4k in 512e drives ;) Thank you!

Why would a 4k native drive be a lower performance? I am just wondering, there are 8 times less operations involved in finding a sector. And there is less overhead from gaps between sectors. That generally means that heads are much faster in acquiring these sectors. Given that how would you...

I understand the differences between different raid setups with ZFS and I've been using ZFS for many years already. I am also aware of the replacement limitations in vdevs created with ashift=9. The real questions here are: 1) Is there any difference between 512e and 4kn from ZFS point of view...

Guys, I will try to keep it very short as I tend to get into unnecessary details. My ultimate goal is to choose between using 512n, 512e, or pure 4kN drives for a new ZFS storage appliance that will either consist of eight 4TB drives in four mirror VDEVs, or eventually Raidz2 in order to...
