Speaking of which, I had a box of about that many floppies retired from the school computer lab. Obviously most of those failed format. Out of maybe 300, I have 15 left that still work. I obtained them in 04, about half were bad then. and only 15 survive today.

Aside from that, I picked up 4 boxes of NOS shrinkwrapped powerbook apple floppy disks from mendelsons in dayton oh. I think there were 3 more left and i never went back up there again.

I only opened 1 box and all of those were still good. so far. not one has failed and I have used the heck out of them for 7.5NAD, and etc..
