Connector and cable: Drives should use standard detachable USB cables so that a frayed or broken cable doesn’t ruin the entire drive.Noise: All optical drives make noise, but the drive shouldn’t drown out the movie or show you’re trying to watch.Price: A good DVD drive shouldn’t cost more than $40, and a good Blu-ray drive should cost around $100.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. Speed: If all you’ll use your drive for is playing discs, just about any drive you buy will perform similarly.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.
