I plan to replace disks in my current home NAS which uses mdadm RAID1 + LUKS.

I am looking at MG10 disks. Specifically MG10ACA20TA or MG10ACA20TE. Both are CMR. The A one has 4k native sectors. The E one has 512b emulated sectores.

I am not sure what difference this makes in 2025? I suppose everything should be able to use 4k now so 4k native should be fine. However, I am not sure if 512 would cause any noticeable overhead...

Part of me wants to just go with the 4K. But MG10ACA20TA is not in stock anywhere local. MG10ACA20TE is in stock everywhere.

Price is approx. the same.

Do you see any drawbacks from one vs the other?
