Our take on the Western Digital WD 3.5" Red Plus 8TB SATA III 6Gbps HDD WD80EFPX-WMC4ZN0

The WD Red Plus 8TB (WD80EFPX) is a 3.5-inch SATA III internal hard drive built for NAS enclosures. It spins at 5400 RPM with a 64 MB cache and uses CMR recording, which matters for RAID rebuilds. It is rated for continuous 24/7 operation in small home and office NAS systems. At $329.99 at PayMore Avon as of November 5, 2026, it sits at the top of its recent price range, so it is not a bargain right now.

Best forHome and small-office NAS ownersRAID arrays that need CMR drivesAlways-on backup and media storageBuyers replacing a failed NAS drive
Pros
  • CMR recording, safer for RAID rebuilds than SMR
  • Rated for 24/7 NAS use with vibration tolerance
  • Low idle power draw, runs cool and quiet
  • Standard SATA 6Gb/s, fits most NAS bays
  • Hardware encryption and password protection
Cons
  • 5400 RPM, so slower than 7200 RPM desktop drives
  • 64 MB cache is small for an 8TB drive
  • $329.99 is near the top of its recent price range
  • No cables or mounting screws beyond the box contents
  • Not a good pick for a single-drive desktop PC

Questions and answers

Is this drive CMR or SMR?
The WD80EFPX is CMR (conventional magnetic recording). That makes it the safer choice for RAID arrays, where SMR drives can stall during rebuilds.
Will it work in my Synology or QNAP NAS?
Yes. It is a standard 3.5-inch SATA 6Gb/s drive and fits most two- to eight-bay NAS enclosures. Check your NAS compatibility list for the exact model.
Is 5400 RPM fast enough for a NAS?
For backups, media streaming and file sharing, yes. It will not match a 7200 RPM drive for large sequential transfers or heavy virtualization workloads.
What is in the box?
The drive and the original box with its originally boxed contents. Mounting screws and SATA cables are not guaranteed, so check your NAS for spares.
Is $329.99 a good price?
It is at the top of the drive's recent range. Two stores list it new, so compare both before buying, and wait if you are not in a hurry.
Can I use it in a desktop PC?
It works, but it is tuned for NAS use. A 7200 RPM desktop drive gives better everyday performance for the same money.
