512n or 512e SAS drives on new server

[Russ Roberts]

I'm buying a HP DL380 server with their P440ar smart controller. I will be installing Server 2016 and Hyper-V. HP offer 2 flavours of SAS drives - 512n and 512e. Which would you buy and why? Thanks in advance.

512n sounds like 512 byte sector native+logical
512e is possibly 4K native 512 logical, which would be a newer drive.

I'm not entirely sure, but that's what it sounds like.
