Great value and works well

Reviewed in Australia on 2 February 2019

Capacity: 4TBVerified Purchase

I ordered 2 of the 4TB drives for my Synology DS418+ as I was running low on storage.

The drives arrived quickly and were well packaged with lots of protective bubblewrap. As these are NAS drives there's no commercial packaging which is just fine.

The Synology NAS had no problems picking the drives up and making the storage available. The longest part was waiting for the NAS to provision the drives.

This is my second pair of 4TB drives, with the first purchase in December 2014, and I've had no issues. Fingers crossed these will continue the trend.

Don't forget to grab your serial number and register the drives with Western Digital directly.

Fantastic for media storage

Reviewed in Australia on 24 March 2019

Capacity: 4TBVerified Purchase

For someone who runs in-home media streaming for his family, these hard drives are the cornerstone for what I do. My Plex server runs 24/7 for access at anytime and as someone who works night shift, having access to my media anywhere is essential. These drives work well and have outlasted every other brand I have purchased to date.

Packaging is perfect, small cardboard box with enough bubble wrap inside it to stop it from moving around and cushioning it from any impacts on top of an anti-static bag to make sure that the drive arrives in working order.

Since I started working sporadic 12 hour shifts, being able to buy my drives online and mailed to my door has been a god send. Thanks WD and Amazon!

I use it as a Desktop HDD

Reviewed in Australia on 15 November 2019

Capacity: 4TBVerified Purchase

Since the price difference is too low I bought this as my main desktop drive. Im a photographer and I have my computer turned on whole day. It's quiet inside my tower and has 130Mb/s write speed. Just plugged in to the PC created a new volume using windows disk wizard. didn't need any additional software. Happy so far. will update this post if it failed.

1 DOA and 1 Drive already open

Reviewed in Australia on 9 July 2020

Capacity: 3 TBVerified Purchase

I have had a 6 Bay Nas for 8 years and after all my Seagate Green drives failed I replaced with WD RED 3TB. I bought 2 of these as ready hot-swappable drives in Dec 2018 when another Red drive failed I l left wrapped in place for 19 Months until today I needed to replace a drive as another 3TB WD Red dated Dec 2013 started to fail (5 1/2 years). On opening the 2 I brought from here on Amazon I found one drive was DOA and appears as if grease has leaked from main motor (Lucky still under warranty to RMA via Malaysia) and the 2nd I found already had the anti-static wrap open.

Quiet and reasonably fast

Reviewed in Australia on 16 February 2019

Capacity: 6TBVerified Purchase

I've filled my NAS with these drives (6TB) and am very pleasantly satisfied with the noise levels (inaudible) and vibration levels (close to none). Speeds are lower than a 7200RPM drive would deliver (this one is 5400rpm) but for NAS with some redundancy it's perfectly fine. Can't comment on longevity just yet

I ordered 2 WD Red 6TB Nas drives. The drives were delivered within 2 days as promised, however unfortunately one was DOA. The refund process was seamless so while an inconvenience, it was not an issue. The drive that worked, does exactly what it was designed for. As far as a tech purchase goes, I could not be happier

I bought 2 of these for NAS and am very satisfied with the performance. They work very reliably and quietly. The operating temperature is cool even with 24 hours non-stop NAS operation. They are not cheap but I am pleased with my decision.

Fast delivery - cant test it yet as this is for a system I wont get to for a few days, but its a good price and with fast delivery. Also it came nicely packaged in multiple layers of bubble wrap outside the static bag - good job.

Fraud? Was shipped an SMR 'AX unit in a bag marked 'RX

Reviewed in the United Kingdom on 21 June 2020

Capacity: 4TBVerified Purchase

Update 2020-11-21: I see now that WD have a Red Plus line which is sold as being CMR only. YouTube videos discuss this and suggest that the new Plus line is an explicit recognition that quietly using SMR for NAS was a mistake. Better still would have been to remove SMR from the Red line completely, but there you go. (Of course this move by WD does not exonerate vendors from committing fraud by mislabelling)

Shingled magnetic recording (SMR) is being used by WD on newer disks. It is measurably awful when used with a NAS. The WD40EFRX (the item I posted this review to) is a CMR (conventional magnetic recording) disk and is very good, I have one in my NAS already. WD now have an SMR 4TB drive, the WD40EFAX (cheaper for them?). So: RX = CMR = Good. AX = SMR = Bad.

I ordered the 'RX (this item). The disk came in bubble-wrap which clearly showed 'RX ... but the disk inside was an AX. See photo. Perhaps just a one-off mistake?

I am returning the 'AX and asking for an exact replacement. Let's see what I get this time.

Same problem with the replacement; the item was mislabeled on the bubble-wrap as an 'RX (which is what I want) but the item inside the bubble-wrap was an 'AX (which I don't want). I suspect the same would happen if I tried yet again. I suggest Amazon check the labeling for all remaining stock of this item.

Qualität des Produkts und Art und Weise der Lieferung sind ungenügend

Reviewed in Germany on 14 February 2018

Capacity: 4TBVerified Purchase

Nachdem ich in den letzten Jahren nie Probleme mit den WD Reds hatte, entschloss ich mich die neueren negativen Rezensionen zu ignorieren und habe mir bei Best-Hardware (100% positive Bewertungen) zwei 4TBs bestellt.

Warum sollte es mir aber auch anders ergehen:
- unzureichende Verpackung in Luftpolsterkuverts in einem nicht mit auf den empfindlichen Inhalt hinweisenden Karton
- erste Platte hatte das bekannte Klacken - tot
- die zweite Platte hatte beim Überprüfen des Garantieablaufdatums doch noch sieben! Monate übrig; Fertigungsdatum war laut Aufkleber der 11.12.2017 - wie geht das zusammen?
Ware geht zurück.

WD60EFRX bestellt - WD60EFAX bekommen

Reviewed in Germany on 27 June 2020

Capacity: 6TBVerified Purchase

Hab extra diese hier bestellt, weil im Titel gesagt wird, dass es sich um die WD60EFRX (RX - also mit CMR) handelt.
Auf der Luftpolsterfolie stand auch die korrekte Artikelnummer - auf der Festplatte selber aber WD60EFAX (AX - also mit SMR).
Bei Amazon reklamiert - zwei Tage später Ersatz bekommen. Dabei leider dasselbe Problem.

Kontrolliert also, welchen Artikel ihr wirklich bekommt!

Et la garantie ?????

Reviewed in France on 6 April 2016

Capacity: 3 TBVerified Purchase

L'enregistrement sur le site de Western Digital m'étant refusé, j'ai téléphoné au service client de WD (ticket # 040416-10923226) qui m'a indiqué que l'article acheté sur Amazon était un disque OEM, c'est-à-dire vendu à des fabricants ou assembleurs d'ordinateurs et que WD ne garantissait pas cette famille de disque ' c'est au fabricant ou assembleur de couvrir cette garantie.
Lors de ma commande sur le site Amazon, j'ai relevé dans la spécification que cet article était garanti FABRICANT pendant 3 ANS. En tout état de cause, il n'était pas indiqué une quelconque restriction de garantie du fait ci-dessus.

Il faudrait d'ailleurs se poser la question sur le droit de distribution de ces articles directement à des consommateurs !!!

VOUS VOUDREZ BIEN ME CONFIRMER L'ETENDUE DE LA GARANTIE DE CE PRODUIT, QUI POUR MOI NE PEUT ÊTRE INFERIEUR A 3 ANS.

Augen auf beim Festplattenkauf

Reviewed in Germany on 13 June 2020

Capacity: 6TBVerified Purchase

Die Festplatte wird im Produkttitel ausdrücklich als EFRX bezeichnet. Bei den EFRX Versionen der WD Red 6Tb handelt es sich um das "alte" Modell mit CMR Aufzeichnungstechnik. Leider entschied sich Western Digital kürzlich, die WD Red 6Tb Modelle als SMR Varianten (EFAX) zu produzieren. Als reine Datengräber sind diese Platten durchaus okay, im RAID-Verbund, insbesondere mit CMR-Platten können diese aber Probleme verursachen. Diese reichen dann von Leistungseinbrüchen bis hin zum "Rauswurf" der SMR Platte aus dem RAID-Verbund. Western Digital hat diese Umstellung leider erst kommuniziert, nachdem User dies selbst rausfinden mussten. Für Western Digital zu Recht ein herber Imageverlust.
Da bei mir im NAS bereits 4x6Tb WD in der CMR Variante laufen, habe ich aus o.g. Gründen bewusst eine WD Red 6Tb mit der Produktbezeichnung WD60EFRX (also CMR) bestellt. Leider wurde mir eine WD60EFAX geliefert. Für mich also gänzlich unbrauchbar und leider hier nicht das erste Mal. Auch bei der hier verkauften Retail-Variante sollte man aufpassen, was tatsächlich zu Hause ankommt.

WD60EFRX = 64Mb Cache = CMR
WD60EFAX = 256Mb Cache = SMR
