On the drive’s end, we prefer the still-common Micro-USB port, though the larger Mini-USB is fine too (optical drives with USB-C ports are rare to nonexistent). But if you’re burning or ripping discs, the rate at which a drive can move data from your computer’s hard drive to the disc or vice versa becomes more important. We didn’t require Blu-ray drives to support reading and writing to Ultra HD (or UHD, or 4K) Blu-ray discs, but we considered it a nice bonus if you didn’t have to pay much more for that feature.
Read and write capability: DVD drives must read and write DVDs and CDs, and Blu-ray drives must read and write Blu-rays, DVDs, and CDs.
