Does anyone know if the controller PERC H310 supports HDD 4kN?

Recently I bought the HDD HGST HUS726020ALN610 2TB but when connecting can not configure.

The message PD MGMT: Capacity: 232.37 State: Blocked

Thank you. With this information better analyzing the scenario we can say that in my case is incompatiblidade (BIOS and PERC Controller). Disk ID 3 is my new disk of 2TB

and in detail we can see: Supported = no Supporte: No

HD can not be configured and used in the PERC controller.

then connected the SATA port: Size recognized in the BIOS: 232 GB

After starting the operating system: HDD Recognized: Yes Size: 2TB

I will use it as well and I will be more careful when buying new HDD.

No, it does not.

The Dell PERC H310 is a rebadged "LSI SAS 2008" RAID controller. As the name suggests, it was released around 2008/2009.

The 4K Native specification was completed in 2010, two years after the LSI SAS 2008 (and H310) were initially released. There were no firmware updates released by either LSI or Dell to retroactively enable 4K "Advanced Format" mode. I note that Microsoft didn't support 4K in Windows until Windows 8 and Server 2012 in 2012.

For most use-cases the performance and capacity benefits of 4K formatting are not particularly spectacular and really depend on your whole system stack (drives, controllers, operating system, and running applications) to be specifically designed to benefit - this article from 2010 running Windows 7 shows marginal improvements at-best: http://www.tomshardware.com/reviews/advanced-format-4k-sector-size-hard-drive,2759.html

In summary: "No, but don't sweat it."

Other answers explain the background well, so please read those too.

I was researching this before buying some 4kn drives, but can now verify that if you flash the PERC card into IT mode (find more info via google), everything should work fine. I pass the flashed PERC card to my NAS VM via PCI passthrough and I have had zero issues.

Flashing the card to IT mode has side effects (decreased iDRAC integration, etc) and should be evaluated on a case-by-case basis, however it seems to have wide support and generally recommended, especially in home/non-critical environments.
