WD Red Pro 4TB NAS 3.5" Internal Hard Drive - 7200 RPM Class, SATA 6 Gb/s, CMR Recording Technology, 256MB Cache

I've been using Toshiba drives recently in my NAS drive, I was impressed with them, but now at only around 3 years of low use i'm starting to see errors in the SMART reporting system. Now I know it doesn't always mean they're going to die imminently....but they could...so it was time to start replacing them, and as i expect 5 years minimum from a low usage drive I decided to leave Toshiba & go back to Western Digital....I've tried Seagate before and found them to be very poor on the reliability front..so WD it is. This is my first time on these particular drives, the Red PRO, it uses CMR technology which is supposed to be a step up from the old SMR technology, faster speeds and reliability, also these have a 5 year, (limited) warranty...the Pro is a little bit more expensive than the basic Red version, but hopefully the little bit more spent equates to a better drive overall with a longer lifespan... Hopefully if it works well i'll replace my other drives with these Red plus ones too.

Bought this 10tb drive to replace a 5 year old 6tb drive in a NAS, as usual with WD its great and time will tell if it lasts. Only thing to mention is it runs noticeably louder than my previous drives

I bought another pair of the 4TB WD Red Pro drives to go in another Synology DS218 NAS, my third now. These drives have the extra benefit of being optimised for NAS working and are heavy duty, and the Synology knows about them and how to make the best use of the system. Except for some chatter when the heads are seeking, I cannot hear them working unless I use a screwdriver as a "mechanic's stethoscope" on the box. The box runs cool. The drives do not come with a fitting kit, but this is not required in most installations which expect to see standard drives and have appropriate mounting systems, as is the case with the Synology. Commissioning and drive checking took about an hour, including unpacking, initialising, updating, and installing all the software and permissions needed. The end capacity in the NAS is not 4TB, but much closer to 3.6TB after big-drive formatting and RAID system are taken into account. However I am happy with this as it is about two years worth of storage, and then it will be time for another newer RAID drive. More smaller new systems with incremental improvements instead of one big old slow one is like having several easily managed baskets for one's precious eggs instead of a big heavy one just asking to be dropped.

The two 4TB discs installed first time on a Synology 216+, each took about 10 hours to complete an extended scan and then recover the data from the existing disc. Automatically increased the volume from 1.8 to 3.6TB. Slightly more noise from the new discs but an acceptable level. The last set of 2TB discs failed with sector errors which is poor since they were purchased in May 2017. The despatch from Amazon Germany was efficient and I was kept well informed, unfortunately the despatching staff did not see the need to put sufficient packaging around the discs. The box was too large for the items and the items had broken the side and top of the box. Thankfully the discs survived, another plus but thats the last time I have an Amazon order sent overseas.

Bought this as a replacement drive for one that recently started giving out messages of imminent failure, in my NAS. I’ve always used WD Red drives in all my NAS devices and find them very quiet, in use. Got the pro version of the drive, as it was such a good price, but I’d have no problem going for the plus, if the price of the pro was too high. The only issue I had with this order was that, as per my photos, the packaging was nowhere near good enough for a computer hard drive. Just a bit of scrunched up paper on top of the drive is not enough as the seller should really be much more careful about how they are shipping out items like this. WD pro drives do have good warranties but I hope I don’t have to use it because of appalling packaging.

Slight overkill but they work, have high MTBF and 5y warranty

I replaced a silent 5 year old 2TB with this WD red 4TB and transferred years of data on to it. 1yr 10mths later this very noisy HD has failed taking all my data with it. NEVER AGAIN

The fittings on your old HDD need to be transferred to the new one/s, there’s quite a lot of noise on initial insertion and the formatting but quite afterwards. Being used in Raid 1 so that the disks can be “hot swapped” when faults occur.

HD durou apenas até o fim do período de devolução e estou pagando por um produto que não consigo utilizar. Não recomendo o produto.

J'ai commandé 3 disques. Il y a juste une feuille de papier cartonnée chiffonnée pour protéger les disques dur. Ce n est pas suffisant. Un disque ne fonctionne pas. J'ai de gros doutes sur la longévité des 2 autres disques dur ?? Un 2eme disque dur présente des secteurs défectueux après l'analyse SMART. (le 11/11/2020 : le 3eme disque contient lui aussi des secteurs défectueux)

Zur HDD selber kann ich kaum was schreiben - und wenn, dann nur positives. Leise und schnell verrichten sie ihren Dienst in meiner Synology. Aber die „Verpackung“, also der PLASTIKBEUTEL, ist eine Frechheit. Schicke gerade die zweite Platte zurück wegen Fehlern. Ganz ganz schlecht und dem Produkt in keiner Weise angemessen EDIT: die dritte Platte kam ordentlich gesichert verpackten und arbeitet fehlerfrei. Geht doch. Dafür gibt es Stern Nr. 5

اشتريته مستخدم بس مكانش شغال فية زنه كبيره لما بيتوصل ومش قاري خالص تقريبا مخبوط خبطه جامده
