Hard drive in NAS for video editing. Do I need an SSD and where can there be weaknesses?

Question

Video processing

I plan to purchase a ready-made NAS for home, since I have neither the knowledge nor the desire to assemble it myself.
It will be used as a storage and backup of all devices, of which there are few, namely: Macbook Pro, tablets and phones. And if I decide to take something from Asustor, then I also want to use the NAS as a 4K media player, the last two versions have models with HDMI 2.0.

Tell those who know whether it is possible (or necessary) to use SSD drives in the NAS. Theoretically, the speed of data exchange over the network between a poppy and a server will be limited by the speed of the HDDs themselves. The Asustor line has 2.5 and even 10 GBit ports. The question is, is it (HDD speed) enough to mount directly from the NAS?

Answer 1

For NVME-SSD (1.3Gb/s) even 10 gigabits (0.9Gb/s) will be a bottleneck.
For an HDD array (0.5Gb / s), a gigabit network (0.09Gb / s) will become a bottleneck.

Answer 2

Thanks everyone for the replies. Decided to put 2 HDD 8 TB. ZFS - interesting but tricky, won't work out of the box. Special thanks to nidalee for the detailed explanations!
