Product reviewsWestern Digital WD Red 4TB,Internal,5400 RPM,8.89 cm (3.5") (WD40EFRX) Hard Drive

What is says on the tin - an utterly reliable NAS drive

Performance isn't the greatest although it's not bad but this drive is designed for NAS use 24 hours a day and it does that job with total reliability. I have had 5 of these disks in my NAS now for 2 years and had no failures at all.

Prior to that I used (brand new) Seagate Barracudas, every one of them failed within 2 years - a 100% failure rate - so now I only buy WD Red for NAS use and I will never again buy a Seagate disk.Read full review...

Use this disk for Building a NAS server

I have built a NAS server using Freenas, an HP microserver and now 4 WD40EFRX, configured as (in raid terms) a striped Raid configuration. 4 * 4TB delivers 12 TB storage. All works well and quietly in the background - its not even housed in the main house to avoid the obvious problem of all in the same place, so the quiet assessment is a little tongue in cheek - id only know if they were REALLY noisy. The server sits there doing its thing 24 hours a day - great job, and I have had no problems with the WD RED disks, two of which were purchased as used,Read full review...

HDD Upgrade

Bought to upgrade a 2TB drive that was close to full. Once formatted (GPT) immediately recognised and a seamless reinstallation was completed without issue. as a NAS certified drive it achieves the highest reliability ratings.
