Typewriters.
They had bars that needed to physically move, and so staggering them helped them not collide and get jammed.
If you imagine a bar coming from the center of each key towards your screen, you can see how the staggering was helpful. For instance, M misses J and K above it, naturally, but it also slightly misses I and the 8 above that.
It’s a great solution for a nonexistent problem in keyboards.
Just wanna throw in a voice saying your setup sounds completely fine to me. Maybe it’s a bit odd but it also sounds like how I’d do it if I had storage needs that large.
My current storage needs are currently met with a 2.5" SSD connected to a raspberry pi shared with samba over WiFi though so I’m pretty sure every storage nerd in here is gonna tell me my opinion doesn’t count, take it with a grain of salt.
