Here's my single story with NAS in 10+ years of software development.

A client had a NAS for their SaaS startup. Disks were having issues. The NAS was a prosumer product that was connected via USB. Had some SATA to SATA cable shipped by Amazon to the garage/colocation facility which basically meant removing the NAS and connecting the disks straight to the motherboard.

Issue solved.

It seems like one of those tarpit product categories that you are just better off by skipping completely, like ORMs, MCPs or reverse proxy HTTP servers.
