Do External CD Drives Have Memory?

Yes.

The 3 most common types of CD-ROM are – read-only, rewritable, and magneto-optical. The different types depend on the material they can be written to. Memory is included in all three of them; it’s just the type of memory that changes with each type. Read-only CDs like music CDs will cost more if they’re made for very high-quality audio sound (red book), while rewritable CDs like computer data CDs will be less expensive for storing bulk data or digital photos/videos which can’t or don’t need to be redone often.
