WD’s Red series is designed for NAS use, and all of the drives come with noise and vibration protection. Right now, WD is mired in a controversy for using SMR instead of CMR tech in select 4TB, 6TB, and 8TB Red drives. SMR is slower and generally not as reliable as CMR, so if you are interested in a Red drive, make sure you’re getting a drive that’s labeled CMR. You can get a 2TB, 3TB, or 4TB Red drive that uses CMR right now, and as long as you’re buying a CMR Red drive, you won’t have any issues.
