FreeBSD with ZFS tends to be less chaotic once setup. Linux distro in storage appliances can be hit or miss, but ZFS/F2FS/CephFS for /home and ext4+Overlayfs for OS / are reliable these days.

Usually, for JBOD file archiving people want to avoid cutting-edge anything. Sometimes Linux kernel less-popular fs updates add or remove data-corrupting fringe filesystem bugs and features. People usually discover this on their own after the first SSD/HDD starts to wear-out, upgrade breaks compatibility, and the solution is re-install/copy-over everything.

Accordingly, I was surprised people now deploy btrfs on linux / for some distro, as your options when things go awry was limited at one time. Would be cool if it was finally production ready, and actually reliable on degraded hardware.

Too late for me, started my own mini vanity NAS/automated-testing project last year with a few built in features similar to https://guacamole.apache.org and Proxmox. If the OS build stops sucking over winter break, than I may share the build-script someplace for people to pull off parts they find useful, and a USB-bootable portable rtx GPU image for test-drive/recovery scenarios. =3
