OT: AF 4k sector drives with 512 emulation
Still have good quality older sata hardware raid cards that require 512
bytes/sector. As far as I know HD manufacturers are not making native 512
bytes/sector drives any more.
Some have better 512e emulation than others. Looking for some advice on
which to avoid and which are recommended. Thanks. PS this is for a CentOS6
server.

512n drives still exist, although they tend to be a bit smaller, 2TB or less.

4Kn drives are appearing now also. I don't expect these drives to be
bootable except possibly by systems with UEFI firmware. It's also
possible hardware RAID will reject them unless explicitly supported.

I too noticed that HGST (now owned by WD) makes native 512n drives. That
pdf states that they come in 2,3,4 TB models. (A6 in the model # represents
512n). But there are almost no reviews on these HGST native 512n drives
online.
