Score: 58/100Rankings
The Rioddas External CD/DVD Drive is a compact USB 3.0 optical drive that reads and writes all common CD and DVD formats without an external power brick. It offers fast data rates, broad OS support, and a sleek brushed-metal finish, but lacks a warranty and Blu-ray capability.
YOTUO delivers a feather-light, dual-port USB 3.0/USB-C optical drive with solid CD/DVD speeds and a rugged polycarbonate case. It excels in portability but lacks universal Blu-ray support and has limited compatibility with some Linux flavors.
