Where WD Red Pro fits

WD Red Pro is WD's higher-performance NAS range: 7200rpm CMR drives with rotational vibration sensors for multi-bay enclosures, a higher workload rating and a longer warranty than Red Plus. It is aimed at busier pools, more users and larger bay counts where the extra speed and endurance pay off.

Workload rating and warranty

WD Red Pro is rated for 300TB of writes per year with a 5-year warranty, double the workload rating of Red Plus. The 7200rpm spindle gives faster sustained transfers, at the cost of a little more noise, heat and power.

Capacities and which NAS it suits

Red Pro spans from around 2TB up to about 26TB, covering the high end that Red Plus does not reach. The larger 16TB to 26TB models are the reason to choose Red Pro, for dense 4-bay-and-up pools and small-business arrays.

Red Pro suits 4-bay and larger NAS, busy multi-user pools and small-business units.

Frequently asked questions

Is WD Red Pro worth it over Red Plus?

If your NAS has four or more bays, several users, or you want the larger 16TB-plus sizes, Red Pro is worth it: 7200rpm, a 300TB per year workload rating and a 5-year warranty. For a quiet 2-bay home NAS, Red Plus is cheaper and quieter.

Is WD Red Pro CMR?

Yes, every WD Red Pro is CMR and RAID-safe. It is the higher-performance CMR sibling of Red Plus, spinning at 7200rpm rather than the quieter 5400rpm class.

How loud is WD Red Pro?

Red Pro is a 7200rpm drive, so it runs a little louder and warmer than the 5400rpm-class Red Plus. In a multi-bay NAS in a cupboard or office that is fine; for a NAS on a desk in a quiet room, Red Plus is the calmer choice.

What capacity Red Pro should I buy?

Red Pro earns its premium at the high end. For 16TB to 26TB dense pools it is a strong pick; below 12TB, Red Plus or IronWolf usually give better value for a home NAS. The table ranks UK Red Pro prices per terabyte.
