In case anyone can't find the security parts I found it:

Locks keep honest people honest.

That's all.

The idea of data security just wasn’t a thing until very recently.

Credit cards sales were recorded using ink imprints of the cards’ raised numbers, and the “duplicate paper” was then discarded with little thought into the trash. Phone books listed names and addresses of anyone who didn’t pay extra to have them omitted (very few people bothered). Checks (the things you wrote and handed out to ANYONE from the phone company to the paperboy) usually included social security numbers, and most universities also used Social Security Numbers as student ID numbers and required them to be printed on just about everything until well into the 90s. Simpler times.

Pretty much everyone I knew who had an Amiga had that box, and from the age of about 6 I was able to jimmy it open easily. Not that I had nefarious intent, just wanted to play Monkey Island.

What kind of sociopath stored their 3.5" floppies with the metal shutter up?

You could get in without the keys if you dropped it from chest height but there would be evidence of accessing the data.

added layer of security i'd say

My dad kept grainy porn gifs (technically, an animated format OLDER than .gif) on 5 inch floppies in one of these. I know it was porn because the lock sucked shit 😌

When I was 13, I looked at web pages about lock picking and then successfully picked the lock on our floppy disk case. Felt like a Mission Impossible operative for two whole days after that.

Pretty similar to a lot of mailboxes

I bet that whole case is just Microsoft Office 97. I remember that was like 50 floppy disks.

Edit: sorry for waking a necrothread. I was unprepared for how stale some posts are in this community.

Don't forget: all those discs have a "write protect" switch on 'em! Can't be too careful.

In reality, it's sometimes appropriate to set the bar at "tamper evident". Basically: did someone fuck with the data while nobody was looking? If the goods are just missing, or the enclosure is forced open (breaking it), you can reasonably answer that question.
