There was a problem filtering reviews right now. Please try again later.
I decided running it as a secondary (D) drive was better for my setup. But now I have the APM issue again. So the drives is constantly laggy because it's always sleeping. It seems to be normal and WD is fully aware as others have the problem. Do a search for WD Gold constantly spinning down and unable to save APM setting.
EDIT 2: Decide 1 Star was a a little harsh. Despite the permanent sleep issue (which I have to run a program called Keep Alive HD...which does a great job) this really is a very reliable and quite drive. No need for SSD for my secondary drive...YET.
Also tried to login to Western Digital support portal to see if I can register this hard disk. But Western Digital does not allow me login in as I am required to change my password. However the "Change Password" button does not redirect to anywhere at their website, without any error messages. It has been over a week now, and the case has been escalated to lever 2 support twice. Still not fixed.
I wanted something that gave the best of both performance AND solid reliability. Typically, NAS rated drives are around 5,200 RPM with longevity their focus, however the WD Gold is a fast 7,200 RPM drive with 128MB Cache and has specs that are close even to the fast consumer grade WD Black drive.
I’ve included some photos Crystal Mark benchmark tests for both ESATA and USB 3.0 for your review. I’m using the Vantec 3.5" SATA 6Gb/s to USB 3.0/eSATA HDD Enclosure (NST-366SU3-BK) found here on Amazon.
I’ve included a couple photos of benchmarks of both the WD Black and WD Gold which may help you decide which is better for your application.
Loving the speed of my WD Gold and feel secure with my data. I hope you found this review helpful.
I noticed after a few hours that the drive was making small intermittent clicking noises. Ticks happening around every 6 seconds or so, quiet enough to not be noticed while playing music or videos, but just loud enough to be heard when things went quiet. I immediately ran a DSKCHK and 3rd part hard drive diagnostic software, suspecting the drive being faulty after all, only to find the drive had no known issues. I opened up the computer case and checked all surrounding drives, unplugging and testing to make sure it was indeed the new drive making the noise. With all other drives unplugged it became obvious the new drive was making the noise. But with no other problems that could be found with the disk, I decided to simply assume it to be a standard noise the drive makes in normal functions.
Now, this may be an overreaction on my part; making a mountain out of a molehill as they say, but I absolutely, positively, cannot stand the noise this drive makes. I've tried to ignore it. Over the course of the first day I barely perceived it, easily drowning it out with a video or music, but now, it's all I can hear. It's akin to Chinese Water Torture, a simple tick, once every 6 seconds, 10 times a minute, 600 times an hour, driving me to madness. Once I truly began to notice the sound, it changed my entire way of life. Where I used to simply sit casually and enjoy some music or videos, I now have been forced by this cacophony to use headphones, hunched over in defeat,in an attempt to drown out the noise. My 350$ 7.1 surrounds sound system sitting in silent, abandoned idleness . I have to force myself to not listen for it, using all my willpower to force it from my mind, which obviously doesn't work as I just notice it more and more each time it clicks. Even now as type this, I can hear it. The tick turned pound, blasting my consciousness away from relaxation and damning me to some kind of rhythmic hell!
So as I do not have to time or money to hire ex-KGB operatives to train me in anti-torture methods I have decided to simply remove the drive and live my life with 4TB less space but an infinite amount a happiness more. I'm not certain if my drive is simply defective or my hearing is simply keener than everyone else's who bought this drive, but as things stand I simply cannot recommend the drive to anyone who owns one or more ears.
Do not recommend. 2 stars.

A bit noisy though - with audible clonking noises - not advised for where that might matter.
Ignore the poor review on here from the guy that doesn't understand the difference between raw and formatted capacity. For reference 14TB manufacturer raw measurement = 12.73TB formatted without any file system overhead.
The Two Larger drives run hotter than the 3Tb drives both averaging around 46'C whilst their smaller counterparts are running closer to 37'C. The larger drives are lower down and the smaller drives sit at the top of the NAS so in a way I was expecting the heat to collect at the top, but after looking into the performance data I found that it's normal for Golds to run hotter and its still well within acceptable range. I've got monitoring and logging in place and will consider installing a large slow fan into the server cabinet to encourage a little upward draft through the stack and push the heat up the chimney running through the spine of the cabinet.
From a Sound point of view I expected to hear more noise from the Gold disks based on reviews and migrating from two to four disks but in reality I've heard little to no difference from the NAS which is still only really audible when it spins up from sleep based on client access over the day, reaching a peak in the early hours of morning whilst backups and Raid Scrubbing tend to be carried out.
Performance is improved, but I'm putting this down to the newer Synology box more than drive speed and I'd think it would only really be valid to start comparing identical RAID Configs using Identical Drive Arrays.
I'll update any of my HDD reviews if I encounter any NAS issues over the years. I've a pile of spare space again now so do not expect to have to swap out drives for around 5 years or so when I will probably pull the 3Tb drives and replace with what ever size is economical at the time...
