WD Red Pro 6TB NAS 3.5" Internal Hard Drive - 7200 RPM Class, SATA 6 Gb/s, CMR, 256MB Cache, 5 Year Warranty

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.

As expected

Early days but seems perfect arrived looking like new 👌

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.

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.

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.

Great product as external HDD for my NAS and more stable and quiet than the previous Seagate I had.But was annoys me so much is the fact that I pay for 2TB, but actually only have 1.83 TB to use. Basically I feel ripped off as I'm missing near 120GB of space that I could desperately use. Now I need to play around as my HDD is already near its limit and I have much more to store.

has a clunky sound like a giant farting in some mountain range a few miles away, i got used to it eventually but its definitely a bit noisy
