Reviews
4TB WD Red WD40EFRX, 3.5" NAS HDD, SATA III - 6Gb/s, 5400rpm, 64MB Cache, NCQ is rated 4.3 out of 5 by 34.
Rated 5 out of 5 by from Top notch NAS HDD I wanted to expand my NAS storage for multimedia purposes. Paired with Synology 218 i run 4k UHD HDR videos in my network without breaking a sweat. Raid 0 as i need more space not security of the files. I am happy with the result.

Rated 4 out of 5 by from Working fine so far What can I say they (2) arrived promptly, well packaged, and are still working three weeks later.

Rated 5 out of 5 by from Nas drive does what it says I bought this to bump up my storage in a Synology nas box. I had 3 or these 4TB drives already that have performed superbly for the last 3 or 4 years. I bought them because my NAS box told me the 2 3tb Seagate drives I had in it at the time had failed. There wasn't actually anything wrong with the drives (that I know of), and I have been using them ever since for other purposes without problems, but at the time I lost everything on them. Netgear wanted to charge me about a grand to recover the drives - so sod that, and after about 2 weeks of trying to hit on the right data recovery solution and I got everything back, but I went with some new WD RED drives for the rebuild. I stuck with the Netgear NAS as I couldn't afford to replace it, which worried me - but I haven't had a single problem with it on the WD RED drives for 3-4 years now. Now I got a new nas, and wanted to expand the storage - so decided to stick with the winning formula and bought another 4TB WD RED. Hard to write a hd review as out the box it really should just work, but my other 3 have performed flawlessly so it feels fair to comment.

Rated 5 out of 5 by from WD do once again what they do best If you have a NAS box that needs populating , these drives are excellent . They are pretty quick, and offer huge storage.
Date published: 2018-01-26
Rated 4 out of 5 by from So far so good I can't really fault these drives just yet although the review takes place in the early days of the life of a recent NAS build for which the WD Reds were purchased. Come back in 5 years and I'll give you a realtime verdict. I'm hoping that the WDs are more durable than recent generations of Seagate drives, both SAS and SATA, none of which have gone the distance. The failure rate of Seagates in comparison with WD or Samsung HDs has been astonishing.

Rated 5 out of 5 by from Ideal for NAS I fitted two of these drives into my Qnap TS-219 P+ six weeks ago. They are working quietly and faultlessly. They replace two Samsung HD204UI drives which were not as quiet and one of which would from time to time disconnect. from the Qnap. I use them to backup images of my my PC HDD each day using Norton Ghost 15.0.. A weekly master followed by six daily increments. A total of around 296 GB/week.

Rated 4 out of 5 by from First drive failed - replacement OK This disk was purchased as an additional disk in a WD MyCloud server. The first supplied disk was DoA. It was quickly replaced and the replacement is still performing well after 2 weeks.
Date published: 2017-02-28
Rated 5 out of 5 by from Great Drives at a good price I ordered 2 of these drives to add to a Synology DS216 Play. WD Red drives are excellent & well suited to NAS devices. They were quickly dispatched by Scan however I have 2 issues. 1) The drives were not that well packaged, only wrapped in bubble wrap. 2) The drives I received were OEM (Out of Region) drives, nowhere on the Scan website is this stated. Had I known this I would not have purchased from Scan.

Questions & Answers

Warranty

The warranty on this is listed as 24 months, however the warranty on the Western Digital Website, as well as for the WD30EFRX (3TB version) is listed as 36 months. Is this a mistake ?

Are these the new NASAware 2.0 versions?

Asked by: ewmanning
I believe these are the new NASAware 2.0 version drives as it does say on the products link. If there is a way of testing this, I will if you want and I can report back. I hope this helps.
