January 15, 201610 yr 4K native Advanced Format disks are the future and adding support for them would only enhance compatibility with today's 512e disks. Please see this thread: https://lime-technology.com/forum/index.php?topic=45368.0 where I do some testing with a 4Kn disk and find encouragement as I prepare it for inclusion in an unRAID array, only to fall at the last hurdle when the array won't start, rejecting the disk silently. I see no reason why 4Kn shouldn't be trivial to support as it's just a simplification of the 512e kludge. Confirming that this feature was added in unRAID 6.4.0-rc8q. Edited September 20, 20178 yr by John_M Feature has been added, thank you!
January 15, 201610 yr We do plan to support this, but need to get one to test with. Probably just a little ways out yet (do not expect this in 6.2).
September 21, 20169 yr It has been 9 months and 6.2 has finally been released! One can only assume that you guys at Limetech are now considering what will go into the next release. Is it too early to ask if 4kn drive support will be included?
September 21, 20169 yr It has been 9 months and 6.2 has finally been released! One can only assume that you guys at Limetech are now considering what will go into the next release. Is it too early to ask if 4kn drive support will be included? How many devices out there are true 4kn? Meaning the logical sector size == physical sector size == 4096? I know there are some but seems to me these will fail in the marketplace because they are just not needed. All it does it let the drive manufactures rip out the firmware that deals with 512e. That firmware is written and mature, and besides all OS vendors (including us) have set things up so that partitions and file systems are aligned on 4K boundaries and use min 4K i/o anyway. There is no technical reason anything has to change at this point. That said, the feature is still on our 'todo' list but it's not very high on the list. This can change if a large customer requires the support though
April 7, 20179 yr I'm not a large customer but I have just bought two 10Tb disks that is 4k native, and it's very misleading when you can use the disks with "unassigned devices" and when you try to add to the array it will not start the array, not a single message why, you can keep pressing the start button efter the page has reloaded. I sure as hell want this feature as soon as possible, having bought two 10Tb disk that I can't use as intended make my stomach hurt.
May 22, 20179 yr Same, would like to see this feature request be a higher priority. More and more drives released today are 4k native that unraid can't handle.
May 22, 20179 yr As someone who's probably going to be picking up a few 10TB disks in the near future: What? Can someone explain this? Why wouldn't those (or other) disks work with unRAID?

Why wouldn't those (or other) disks work with unRAID? You can buy a 10TB disk, the majority of disks are still 512e only, for those that exist in both options just make sure you choose the 512e variant, most (all?) models that are available with 4kn also are available with 512e.

July 11, 20178 yr I'd like to throw my hat into the 4kn support as well. The sooner it can be supported the better please. Much appreciated!
July 30, 20178 yr It's pretty shady that this 512e requirement is not in the hardware requirement list or any of the official documentation. So glad I bought a Pro license and can't use my 10TB disks.

So glad I bought a Pro license and can't use my 10TB disks. I agree that it's not good to have to search the forum for this info, but to be fair, limetech has a generous trial period before you are required to purchase a license. That trial period should be used to fully evaluate what you want to use before you spend the money. I'm sure they will add 4kn support ASAP, but who knows how long it will actually take. There are MANY requests and modifications that are being worked on right now, and 4kn is on that list.
