Is it possible to combine disks with different sector sizes in one raid array?

Question

linux

There were several disks and an old server lying around here at work, so I decided to collect a file washer on it.
I chose larger disks, namely:
WDC WD2003FYYS-02W0B1 - 2 pieces
WDC WD20EARX-00PASB0
WDC WD20EARX-008FB0
The last two have Smart Sector Sizes in the parameters: 512 bytes logical, 4096 bytes physical
The first has 512/512.
What does it affect?
fdisk swears that the size of logical sectors is less than physical ones and slowdowns are possible.
I wanted to make raid 10 via mdadm - what is the best way to proceed?

Answer 1

The last two with 4k sectors (you can read more here ) and 512 emulation will work like 512.
fdisk says that it will work a little slower than a regular 4k disk, the difference will be 5-10%, you won’t notice at all compared to regular 512.
Collect calmly through mdadm and use it, everything will work fine
