Questions about the QNAP TBS-464-8G-US

Hi,

I have some questions about the QNAP TBS-464-8G-US.

1- Can I put 4 8 TB WB-Black in it ?

2- Is this heating a lot does it need heat sink for the NVMe and does it have enough space for the NMVe and Heat sink ?

3- Is it possible to configure each drive as single drive ?
