Western Digital 16TB WD Red Pro NAS Internal Hard Drive HDD - 7200 RPM, SATA 6 Gb/s, CMR, 256 MB Cache, 3.5 - WD161KFGX

I purchased 5 18TB drives and have only received 3 so far. One was a 6TB drive that was mislabeled on the unopened package. I got a replacement and it was the proper size drive, but was DOA. The two drives that have worked are running great. I was able to backup just over 20TB between them and the speeds have been as expected.

I use a Synology Nas you can put these drives right in easy I have multiple of them that Ive been running for years flawlessly the only reason I change them out is now Im going from 4 terabyte to 10tb itll be nice to see him get a little cheaper down the road when the twenties come out but they are a solid product thank you WD

Drives are fine as long as they are consistently running, but they get noisy going from sleep mode and back. I am using in a personal raid 1 archive and they work great, but these drives are made more for a server array.

Used this to replace a failed drive in my NAS. Installed smoothly, and its storing information. The most important feature of any hard drive by *far* is longevity, and I wont know that for quite a while. But initial impression is it works just fine.

The performance of the drive is great -- fast, efficient and no delays. The read/write operations are very noisy. Youll want your NAS in another room or it will drive you crazy. Also, the drive does a heartbeat head noise every few seconds ALL DAY LONG. With the noise of the drive, this will also drive you crazy. I tried another brand (T*****a) and they are nice and quiet with no heartbeat.

I have a home lab with a NAS thats central for most things running. Last fall I realized the old disks were passing 8 years of total run time (and less than 50 Power On cycles) and not only were the old drives showing their age as in lacking good cache but I figured it wouldnt be too far off into the future before the drives would fail, so I started to replace the drives. Same housing, same hardware (Except for the disk) same software - once data was migrated over, nobody would be able to tell the difference except the newer disks were faster. And I was pretty happy - that is until last week. This disk was D-E-A-D - a ton of read errors, and no way to even send a command to the drive. I removed the drive and started testing it, to look at SMART data finding a looong list of errors (192) and a Raw Read Error Rate sky high (almost 500K). The log is showing failures even at PowerOn - its as if the drive is having a hard time talking back to the controller. The drive gets EXTREMELY hot being powered on for just a few minutes. So this is going the way of RMAs once WD gets back to me. Had I written this review a month ago it would be full 5 stars and never had a problem kind of review. Having replaced 4 drives with a very long run time without major issues this is a bummer. It happens - sometimes a drive is just bad, except in this case WD added to my frustration with a web-site that would not initiate an RMA for me.

These drives don’t have all 3 side mounting screw holes. Only the fore and aft. WD seems to have tried to save a few Pennie’s by omitting the middle 6-32 mount holes which my drive carrier requires for 4 point securing. Had to hang these off just the back 2 screws. Hope they last. Should have stayed with seagate.

As an IT professional, I have replaced my share of hard drives and I was impressed to say that of all the drives I have replaced over a 20 year period of bring in IT, I only have replaced 3-4 failed Western Digital drives. And all of these were 5-11 years old. They ran a good life. Today for the first time ever, I received a DOA WD drive. The worst part is that it was one of their professional top of the line drives, a WD Red Pro! What a let down this was. I have lost a lot of confidence on WD after this experience and can no longer blindly recommend them. Its now worth looking at the competition before making a decision. I still have more bad than good experiences with WD, but getting a DOA Pro drive is not ok.

I just installed two of the 4TB Pro versions in a two-bay Synology NAS. Only time will tell if theyre reliable. Im using them as a file dump at home, so Im not exactly pushing the limits of their capabilities. I had no issues whatsoever setting them up in a Raid 1 configuration. Its been quite a while since I picked up a WD HDD. One thing I forgot about is how much noisier they are compared to the NAS-rated Seagate HDDs Ive used in the past. In fairness, the DS220j in which I installed them is far from soundproof, but WD HDDs have this harsh, grindy quality to them that I just havent experienced with comparable Seagate drives. Its not such a severe problem that I wouldnt recommend buying these drives. Its NAS storage. Reliability is paramount. But its surprising to me that WD HDDs still make the same muffled pops and crackles that they did 12+ years ago, specifically, a 2.5 WD Black HDD I put in my PS3. In my experience, Seagate HDDs at comparable performance levels sound less harsh. Again, its nothing severe enough to put you off buying these drives, but have some distance between you and your installation.

I have fifteen of these drives installed in three separate NAS devices. I purchased two of these 8 TB drives to upgrade my memory capacity in one of my Digital Robotics (Drobo) NAS devices. These two drive units have been in use for about three weeks. As I understand it WD began offering these RED PRO drives specifically for a RAID application (my Drobos are) From the WD information - Since your NAS system is always on, a reliable drive is essential. With an MTBF of up to 1 million hours, the WD Red Pro drive is engineered to tackle 24/7 environments. I am a small tax practitioner and need reliability for all of my backed up files. I do have one important consideration. WD warrants these drives for five years. Unless their warranty policy has changed, a customer would be expected to return a defective drive to WD for testing and evaluation to confirm that the failure was within their warranty clauses. However, I am NOT going to send in one of my drives with some extremely sensitive tax client information just to have it replaced under warranty. However, I did have had one fail several years ago. I contacted Western Digital Customer Service and explained the situation. I was provided with a Confidentiality Waiver to complete. I submitted it to WD and the drive was replaced under warranty.
