BD-R DL: USB 3.0 High Speed Interface: Portable size is equipped with USB 3.0 high speed interface, bringing you faster data transfer speed and stable performance, compatible with USB 2.0 and USB 1.0.
Ready to use out of the box. Works very well. I was able to read older CD-RW that I couldn't read with other drives. Fast and reliable (and very reasonable in price!).
