These HDDs are highly recommended and I have had great luck with WD drives in the past. They are set up in a raid 1+0 and are used as daily back-ups of work data on a TB3 external enclosure. Throughput is good and they continually pass all diagnostics. The reason for 3 of 5 stars is that at least one of the drives and likely 2 are very noisy. They rattle, clank and gurgle when accessed (not the head crashing type of noise). Because of that I may be replacing them. The shopping exp was good, delivery was fast, packaging was excellent, performance as stated is good.

I bought this drive because I was very mad about my lack in storage in my server, this was the best purchase that I have ever made. The drive is very reliable and has been through quite a few power outages and brownouts before I got a UPS and it's still trucking along like nothing ever happened. The performance of this drive is very quick as long as you have the system it is put into configured correctly. The only slight issue I have is the drive is quite loud while it is doing a SMART test, but I don't see that big of a problem with that because it is a standard thing that makes sure the drive is functioning correctly.

I purchased 3 of the 4-TB Gold hard drives a few weeks ago and have not had any problems with them. The 7200 rpm feature makes the read/write function really fast. The main thing that I want to mention is that these drives are quiet - no click-clacks resulting from drive head seeking motions. Only time will reveal to me how reliable they are.

Got the Gold for the size and speed, but video files are slower to load than I'm used to. I can't figure out if that's a problem with my new computer or the HD.Another problem is the loud grinding noises it sometimes makes. Maybe because of it's size? I ran checkdsk and it said it was ok, but I can't help but worry about it now. Sometimes it's normal HD sounds, but sometimes it's sounds like metal on metal grinding.Also, I wasn't expecting the 14tb to be only 13tb, so now I regret not getting the 16 because I'm running out of room already and my new computer only has one space for a 3.5 hd.I ordered directly from WD and it was shipped quickly.
I replaced two, 6TB UltraStar drives with two, 18TB Gold Enterprise drives in my RAID chassis, which I use as a Time Machine backup for my Mac computer. I've had the drives for a couple of weeks now and everything has gone swimmingly. The only complaint I have is the noise level of the drives. Since the Gold Enterprise drive specifications are similar to that of the UltraStar drive, I expected the same level of noise. What I found, however, is the Gold Enterprise drives are noisier. You can definitely hear the read/write heads shuttling around in the drive. There is definitely room to improve the drive design in this regard. Aside from the noise, I am satisfied with the drive performance and am hoping I get the same level of reliability with the Gold Enterprise ...

I chose to order directly from Western Digital to ensure the drives were covered by their 5 year warranty. The drives came within a few days of purchase packaged in a box that provided exceptional protection.
I have installed and used many of these drives. Not 1 has been DOA and several have been going over a decade (Including Black HDD). Only problem is that both times I got a warranty replacement (failing smart-but still working) they replaced them with lesser drives. Granted they were close to the end of warranty, but a blue drive is NOT a replacement for an enterprise drive. I haven't had problems with the RMA process and turn around was fast, just not equal replacements.
I bought two of these when they were on sale for $250 off. I use them in a RAID0 array for a home server I have setup. The drives contain the large, infrequently accessed files the server serves. The drives perform well against all benchmarks I have thrown at it. I have had no data failures in the time I have owned it.I will however issue potential buyers this warning. WARNING: Not made of gold. Even though the drive claims to be gold, it is in fact made with the same non-gold materials just like any other drive. There may be gold inside, I'm no hardware engineer.Also, while the description of the drive says "Enterprise Class" I have yet to be called "classy" by anyone accessing the server. I assume this is because it will take time for the Enterprise Class to ... MoreI bought two of these when they were on sale for $250 off. I use them in a RAID0 array for a home server I have setup.

I assume this is because it will take time for the Enterprise Class to take affect. No stars taken away for this... yet!And one last bit of miscommunication about the drive, likely due to my ignorance about drive terminology, and upon which I hold no umbrage: The drive is advertised as 16TB, which of course I and likely any other buyer would assume is a reference to Terry Bradshaw and the Pittsburg Steelers scoring 16 points in their 1974 Superbowl win. It, however, refers to the drive having a capacity of 16 "terabytes."
I really appreciate being able to buy directly; this is a large plus. The drive was shipped quickly and was well packaged. The 2TB version is quiet, which is important for my use case as the array is in my office. The write speeds when tested with HD Tune prior to adding it to the RAID array was 190 maximum, and 156 average, which is close to the published max read value. I will be buying more of these to expand the storage in the future.
Have not had this drive for a long time, but it is very quiet, checks out with no problems and works just like it should. It backs up my little NUC every day. This drive works out to nineteen dollars per terabyte so I back up everything to this drive with no compaction. I may buy more if the sale lasts. My other WD Gold drives are about five years old now and keep running perfectly.
Love it so far. With its long warranty, I have the confidence to trust this drive with my data. I purchased two and have them in a Sabrent JOB enclosure connected via USB 3.2.As long as it works and delivers the rated speeds in the years to come, what's not to like? I gave it 5 stars, although if I wanted to quibble, I'd probably take away 1 star for the unusual noises it makes during operation. It's not particularly loud, however, so it doesn't bother me much.
