It would be nice if it fit on a standard size 1.44MB floppy, but given that I haven't used a floppy drive in about a decade, yeah I guess it doesn't matter much.
I think my current motherboard does not have pins for a floppy drive, but every motherboard I've owned before that does. I just kept moving the floppy drive from chassis to chassis every time I upgraded just in case I needed it. IIRC the last time I used a floppy was either to archive old data to CD-ROM or boot the computer when I couldn't find a USB thumb drive.
I do still own my first computer, an IBM PS/2 Model 50Z, which still has its original floppy drive. Other parts I upgraded -- the 286 was replaced with a 386 SX/Now!, the 30MB ESDI was upgraded to 100MB, and it now has a full 2MB of RAM. I keep the floppy drive because it reads disks that no other floppy drive has been able to read.
