Plextor today announced the PlexWriter 24/10/40U CD-RW drive, which features USB 2.0 connectivity. The drive operates as a USB 1.1 device under Mac OS 8.6 and later (and is therefore limited to 4x writing speeds) and as a USB 2.0 device under Mac OS X. The US$229 drive also features Burn-Proof technology, and while no Mac software is included, the drive is Mac compatible.
