Questions and answers

Is the WD80EFPX CMR or SMR?
It is CMR (conventional magnetic recording). That matters for NAS use because SMR drives can stall badly during RAID rebuilds and sustained writes.
Is it worth it over a WD Red Pro or a cheaper desktop drive?
For a small NAS, yes: the 180TB/year rating and NAS firmware (TLER) make it more suitable than a desktop drive. A Red Pro adds 7200 RPM speed and a longer warranty, but costs more and runs louder.
Will it work in my Synology or QNAP NAS?
It is a standard 3.5-inch SATA drive, so it fits most 2- to 8-bay Synology, QNAP, TerraMaster and TrueNAS builds. Check your enclosure's drive compatibility list and bay size first.
How loud is it?
At 5640 RPM it is quieter than 7200 RPM drives, with a soft hum and light seek noise. Vibration can add up in dense multi-bay chassis, so use the mounting screws or trays.
What is in the box?
Just the bare drive. No SATA cable, screws or mounting bracket are included, so have those ready before installing.
When is it cheapest?
NAS drives tend to dip during Black Friday and back-to-school sales and when larger capacities launch. At $328.17 as of November 5, 2026, compare against the 3 stores listing it new before buying.
