I’m setting up a new hard drive and formatted it as exFAT. I liked the cross platform support and not having to deal with permissions when mounting the device. BUT it doesn’t support hardlinks, which I want to use for the *arr apps. Is NTFS the best pick, and I’ll just have to live with read only on mac?
ZFS?
I’m a big fan of ZFS, and I use it extensively. For a single hard drive, though, wouldn’t ext4 and a few NFS shares make a lot more sense?
My recommendation would be to use a hard disk in a single computer, and to use a single operating system for a single computer.
Then you pick the most capable, fastest, native FS that fits your bill.
If you need to transmit data between computers, use the network. It’s that it’s there for.
It might be time to virtualize.
Use a network share
I just use ext4 on everything. It works pretty nicely.
