Which disk to use?

[rockberto]

Hello to all and sorry for my bad english. I'd like to know what is the maximum capacity of each hard drive and the better model I can use in zidooo uhd2000 (western digital red, or
 seagate ironwolf etc...) I'd like to use two 12 tb or 14 tb.
Thanx in advance

14TB is the max I know to have been tested although larger should work.

Speed is unimportant for media so I'd be looking at noise and price as main factors. WD Red is a good choice.

many thanx!

There is no actual limit.

Somebody reported a 16TB Seagate Ironwolf working too.

Can these players support external hard drives of 20tb?

I would be very careful buying such a drive. Above 16 Tbyte 512e AF (=Advanced Format doing 512 Byte sector emulation) won't work anymore and these will be 4Kn (=4K Native with 4K Logical and 4K Physical sectors). I doubt these will work with Android? Never tried one.
Maybe via USB there is still a trick possible but Internal/SATA I doubt.
