I'd like to have a 3, 4 or 5U chassis with a bunch of pass thru JBOD disks for swapping out my volumes. I'm looking for ideas on how to put 3.5" SATA drives into some caddy that's not much bigger than a 3.5" but will protect the data, power, and PCB of drives when removed and uses as little real estate as possible in the chassis to pack the disks in. The most I've seen is 12 x 5.25" in 4U which looks like it'll only fit a single disk into each 5.25" bay.
Is there anything you've seen like this to fit more disks?
