While I am enjoying this discussion on storage devices… ssd/hdd/nas … what I originally looking for was how do you organize/store the actual devices to help keep the desktop space organized.
Again OP, you have to provide key details to get good help. Do you want to store them someplace while they are still connected to your Mac? If so, that would be wherever you can route cables and power. Depending on your situation, you might be able to drill a hole through a wall and store them in a neighboring room/closet... or drill a hole in the back of a desk and hide them in a drawer. There are mounts that could hang them on a wall... or velcro them to the back of a monitor or back/side of the desk. There's
a little shelf that can hang off an iMac/ASD stand that holds & hides an enclosure or two. You could buy monitor stands with shelves and store them in the shelves (
one of
many examples). You could buy a shelf to attach under the lip of the back or side of the desk and store them all there (
one of many examples). Rolling cart that tucks under the side or back of desk (
one of many examples)?
Though I haven't tried it (and formatting may be an issue), I believe you can connect a multiport USB hub (
one of many examples) to your Synology and then connect each USB enclosure to it and it will make them like their own mini NAS storage drives. You might be able to do the same trick if your router has a USB port (easy enough to try).
Or do you mean when disconnected? if so, that can basically be
anywhere in your home: closet, pantry, fire safe, hidden safe, under a bed, cabinet, etc. Try to avoid places with extreme temperature variations, high humidity and/or strong magnetic fields.
If bare drives, you can buy big JBOD boxes (
one of many examples) and store them in the slots. Or
plastic cases. If they are all in their own enclosures, see above.
