They are not reliable at all. And if you don't want to use USB... well good luck finding a modern motherboard with a floppy disk interface. These days you obviously have to use a USB floppy disk readers. The argument of not using USB doesn't make a lot of sense, USB is not dangerous, it's how the OS is configured. Also how do you plug in mouse and keyboard, with PS2? And by the way, if you don't want to use USB at all you can use an SD card (you can find readers that are PCI express and thus don't require USB), or a CD ROM with a SATA reader, or a SATA HDD with an hotswap caddie, etc.
