Hello
NAS noob here.
I've just purchased a Terramaster F4-423 on Amazon black friday sale.
Haven't heard great things about their operating system TOS so I've decided to change the OS (I have not yet) to TrueNas Core (after some research). I will probably go with the ZFS file structure as I think I may be able to add more drives at a later date. I will most likely purchase two 4TB HDD's (for redundancy. How good is ZFS at redundancy? With the HDD's how much redundancy will I need if I want to use one as a fail-safe if the other dies?
Additionally, are there any other NAS operating systems that are good?
I will mainly be using my NAS as a file storage device and a plex server (4K). I have a 1GBPS internet connection. I'm not too worried about accessing it remotely.
Also, I have heard that to install TrueNAS you need 32GB ram. However I have 16GB ddr4 3200mhz, is this enough?
I also thought about purchasing a few NVME's as the device has two slots. I was thinking of using one to install TrueNas (as it is not good to leave the USB in the motherboard) and the other to use as a caching drive. However after some research, I have heard this may not be necessary for my use case?
Also, will I be able to add more drives (easily) with ZFS at a later stage?
Apologies for all the questions, any help is appreciated.
