KNX.
Everything is decentrally programmed, and you can do extra automations and stuff from home assistant, but KNX devices are wired (generally) and will always Just Work™. More expensive that the cheaper retrofit options, but if you factor in manual overrides or getting the “better” wireless smart devices it is comparable. They generally also have a manual override at the panel. For core functions like lights, HVAC, roll shutters or blinds, etc… That is honestly the best option (unless you want every light to be an RGB light for some reason, then you still need smart bulbs)
Some drives are worse than others and higher capacities get worse and worse, in my experience, Seagate drives are extremely loud.
If you get helium drives (like wd red plus > 8TB i think),or 2nd hand hgst/ WD enterprise drives) they are significantly quieter.
But, having an ssd is cheaper probably. I have an SSD for the boot drive and all databases, configuration folders, etc… In docker so general IO is fast, then media, documents, pictures, etc… On the big HDDs.
