most write protect switches are "advisory" and enforced by the computer OS. does this actually disable write at the usb flash drive level?

It physically stops writing and has saved me countless times from viruses.

what is a read-only flash drive?

The flash drive is actually conditionally read-only, depending upon the position of the read-only switch. In the read-only position, the drive cane be read from but not written to -- this is useful if you want to use it to store a clean copy of an operating system installation disk (especially since a fair number of modern computers do not have a CD/DVD/BluRay drive, let alone floppy drive, that would have served the same purpose in past years) -- you never know when you might need this if your computer develops a persistent crash or virus/worm/Trojan horse infection. In the other position, the drive can be written to -- this is how you put the clean copy of the operating system installation disk (or whatever) on there in the first place (from a known good system).
