4k native sector drives still not supported by RST?

Community Manager


just want to ask/confirm before buying a new hdd.. even with latest hardware/software (z170 uefi board, windows 10 in uefi mode, latest drivers), intel RST driver would still not support a 4kn drive, only 512e (with emulation)?

this old article is still correct? - "Intel® RST does not support 4k native sector size devices."

windows 8 / 8.1 / 10 officially fully support 4kn

seagate already offering 4kn sata drives (alongside legacy 512e models) too.

but for use with RST still not ok to buy?

512e may be bad for performance (as opposed to native)

so for new PC i was hoping to get 4kn, but i need RST driver to work with it too..
