Is the WD120EFGX worth it over a cheaper 12TB desktop drive?

If the drive lives in a NAS, yes. Red Plus is rated for 24/7 operation and vibration in multi-drive bays, and it uses CMR recording, which desktop drives at this price often do not. For a single external enclosure, a cheaper drive may be enough.

Is this drive CMR or SMR?

It is CMR. WD lists the 12TB Red Plus as conventional magnetic recording, which keeps write speeds steady and rebuilds predictable in RAID.

Will it fit my Synology or QNAP NAS?

It is a standard 3.5-inch SATA drive, so it fits most multi-bay enclosures. Check your NAS maker's compatibility list for the exact model before buying, since some vendors restrict drives not on their list.

At 7200 rpm it is louder than 5400 rpm Red models. Expect noticeable hum and seek noise in a quiet room, so a NAS in a closet or office corner is a better fit than a bedroom.

What comes in the box?

The drive itself. No SATA cable or mounting screws are included, so have those on hand if your enclosure does not supply them.

Large-capacity drives tend to dip during Black Friday and other storage sales. At $399 at eBay as of November 5, 2026, it is worth watching for a drop before a planned array expansion.

Our take on the WD WD120EFGX Red Plus 12TB SATA Hard Drive for NAS

The WD120EFGX is a 12TB 3.5-inch SATA drive from WD's Red Plus line, built for NAS enclosures and multi-bay servers. It spins at 7200 rpm and uses CMR recording, which matters for RAID rebuilds and sustained writes. The best new price is $399 at eBay as of November 5, 2026, and only two stores list it new, so comparison shopping is thin.
