I plan to have my 3.5 in sata hard drives set up so they are swappable. I am using icydock enclosures. Some of the hard drives will be kept in storage cases, as I do not space on my desktop for them all. is it safe to store the bare hard drives in cases in the drawers of my wooden desk? is it safe to stack them? is it best to store them flat in the drawers? or can I have them sitting vertically to save drawer space? to anybody who has drives & swaps them out, do they store bare drives in cases like this?
