Hi all,

I've a two disk RAID-10 (far 2, I guess).
One HDD seems to be going to the HDD heaven,
so I'm planning to change it.

The most convenient HDD I found has 4K sectors,
while the actual ones have 512 byte sectors.

It is a 4Kn drive, or a 512e drive? If it's 512e, as long as you add the whole disk or ensure alignment, it's OK. For 4Kn drives, that may be a problem. But so far I've only seen 4Kn drives as large 3+TB external USB.
