I have no idea. I treat this as commodity (practically) –
HGST Ultrastar – whatever number comes up. Get the iX, not the X for the Netstor.Bob Zelin

That’s 3 internal and 1 external though ? :/
The diff is 512 bytes or 4k sectors
4k has 512 emulation.
Areca can handle both fine apparently.

arc-1883ix-16 is what you want. Go to the Areca website, and look at the spec sheet, you will see everything.

Boy Simon, I am confused –
the new cylinder Mac Pro has no slots. You take the Tnunderbolt port and go into the Netstor, and INSIDE the Netstor is where you put the ix card – so the 16 drives connect to the internal connectors. The ix has one external port for SAS expansion.
If it only had external ports, how would you get it to work with the Netstor and the new cylinder Mac Pro ?bob Zelin

I’ll be using the 2008 Mac Pro for now with the external SAS netstor’s we have.
Hence externals.

Advanced Format (4K sectors) is what you want. It’s better if you can use it. Not all cards support it, which is why the drives support 512 byte emulation. You don’t want to be using that since it’ll be worse than native 512bytes. So long as the card claims to support advanced format, you’re good.
