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

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.

AFTER NOTE: Finally, resolution...It took several (at least 5) interactions with Customer Service, none of which were possible by phone, but the issue is finally resolved. Western Digital replaced the drive (finally agreeing to pay shipping back the bad drive to them). It took additional attempts for acknowledgement of my return of the bad drive shipment back to them, which then finally activated the full 5 year warranty on the replacement drive. Their default is 120 days, seriously, so if you do buy this and have to return it, be diligent! They just seem overwhelmed in Customer Service. ORIGINAL Which is worse? A hard drive with a 5-year warranty that dies after 33 DAYS, or the company that makes them --in this case Western Digital -- responding unreasonably with rigid rules that are far from appropriate. From my point of view, for a business, the purchase of the hard drive is not just the sheet metal and magnetic discs needed to put them together, it is the company backing the drive, ensuring its reliability. To be fair, I have owned 3 Red drives used previously for three years without a problem. This specific purchase was for 4 drives to be used in a Synology DS918+ NAS. I moved up to these Pro drives because I was concerned with the period AFTER 3 years, not the first month! The drives installed easily, seemed (on the outside) to be constructed well and were packaged appropriately for shipment. Yesterday, the NAS reflected significant degradation in one of these 4 drives, to the point of not being usable. I figured even good companies have a few buggy drives so I went to the WD website, which was buggy in and of itself and incapable of processing an RMA. So then I called the company this morning. I was informed that I could ship the drive back to them (AT MY EXPENSE) and they would ship me another drive (re-certified) upon receipt. 10-15 business days (thats two-three weeks, folks). The alternative was I could get premium service, if I gave them my credit card number:They would reserve the full retail price of the drive on my card, ship me a NEW drive now, and release the amount on hold when they got the drive back. Again, shipping on my dime. When I pointed out that it was 33 days (the drive had itself only actually been at work for about three weeks), they said that they would escalate the case, and try to get free shipping, but that if I wanted a NEW drive, they would still need my credit card...even though I explained to them that I was happy to return the drive and wait for them to get it before shipping me the new drive (I bought another drive as a standby for the NAS). They said they would escalate and see. That was about 12 hours ago...still waiting to see. As a business person, I rely on machines...but more importantly I rely on the good faith of the companies producing those machines. When the machine fails -- which happens -- I expect the company to back them up, and do what is right. Right now, I cant even get a straight answer from WD. As some in Washington are known to say SAD!!! Two stars in respect of the WD drives that have worked for me in the past.

These are not retail units, the warranty will not apply to these units. Unit its really loud when it spins

Bought the 18 TB variant, definitely not the best packaging for a $400 hard drive. The drive works but I hate the occasional loud clicking noise from head parking or some advanced power management (APM) feature that I couldn’t disable. APM resets minutes later after I disable it. I tried several disk management softwares with no luck. It must be the firmware. Why put APM on a NAS drive that is meant to run 24/7??

Purchased to upgrade a system that has some failing drives. Install and resilvering was quick and easy.

I generally have nothing bad to say about WD drives. I still have 8 2nd gen WD Red drives from 2012 running. Have not tested for errors, but last I checked they were fine. My WD Black drives reached over 35,000 hours before reporting bad sectors- they still survived to transfer my data and rebuild the array. These are my first purchase of the latest generation NAS drive and I hope they do as well as my former WD black. I will continue to replace failing black drives from 2011 with these Red Pro as needed. Hopefully prices will start coming down within the next year or two.

I BOUGHT 2 HARD DRIVES FROM NEW EGG AND AFTER SEVERAL DAYS OF TESTING WITH QNAP; THEY WERE DEEMED, DEFECTIVE OK......THAT HAPPENS. BUT I HAD INSTALLED THESE INTO A NAS AND HAD TAKEN OVER 2 WEEKS GOING BACK AND FORTH WITH QNAP IN MY SPARE TIME TO DIAGNOSE THE HARD DRIVES. NEW EGG WILL NOT TAKE THEM BACK BECAUSE I DO NOT HAVE THE ORIGINAL PACKAGING. I HAD PACKAGING FOR 2 OTHER HARD DRIVES (BLACK). SAME SIZE BOX ETC. ETC. WILL NOT TAKE BACK AND GIVE NEW ONES!!!! WHAT IF THESE WERE IN THE NAS FOR A YEAR? AM I SUPPOSED TO KEEP THE BOXES FOR THE HARD DRIVES UNTIL THE DAY I THROW THEM OUT? DOES NEW EGG THINK I AM INCAPABLE OF PACKAGING UP 2 HARD DRIVES SAFELY? I WAS REFERRED TO WESTERN DIGITAL TO GET REPLACEMENTS. THIS MEANT OPENING AN ACCOUNT AND SENDING THE HARD DRIVES TO THEM AND WAITING FOR REPLACEMENTS........WHICH CAME AND DO WORK. THE POINT IS, THAT TOOK ANOTHER 2 AND A HALF WEEKS. SO FROM THE ORIGINAL PURCHASE OF DEFECTIVES UNTIL I HAVE WORKING HARD DRIVES TOOK OVER A MONTH. ALL THIS FOR 2 DEFECTIVE HARD DRIVES THAT WERE ROUGHLY 2 WEEKS OLD. NEVER AGAIN NEW EGG!!!!

These are the only drives I will ever use for my NAS. Rock solid.

First things first. This 2TB Red Pro drive is CMR (not SMR) technology, which is a relief. In any event, I installed these drives (2 of them) in my quite old, Synology DS211 NAS and thus far have had no issues at all. Pretty happy with them. I havent done any performance testing and this is just an occasional use device, largely for archival storage. I did upgrade to Synology DSM 6.2, no problems there either. All the drive features seem to work including sleep mode and S.M.A.R.T and other drive management technologies. Im mostly happy these drives were not SMR, that was my biggest concern. As far as noise, when these drives are spinning they are pretty darn quiet... literally cant hear them at less than 3 feet from my head. They do make some interesting noises when going into sleep/wake mode however.. very bizarre sounds. Vibration seems non-existent as well. I did have some older WD drives in this NAS for almost 8 years and they seemed to occasionally have some harmonics, these new Red Pro 2TB drives dont seem to have that issue at all. Good luck!

This is a review for a drive that was purchased from Amazon and fulfilled by Amazon. I received a new drive in new (sealed) packaging. It was exactly as expected. I was able to verify the 5-year warranty with Western Digital and register in online. I have installed it in my system and it is working correctly so far. Should that change, I will update this review. I cant speak for other sellers in the marketplace, but as I stated... I got from Amazon exactly what I ordered.
