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

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??

I installed these drives into a Dell PowerEdge R210 II and they are working flawlessly so far. Its been a week. They are running in an Unraid server. I was thinking that they may need jumpers set to support 3Gbps SATA settings, but they worked magically out of the box.

Having a synology NAS, I know to test drives first before installing now as it creates a nightmare if you get a bad drive when trying to rebuild an array. Arrived sealed, although not a tight seal, so who knows but it gives a little bit of peace of mind.

The drives turned up and are running very happily in my NAS.

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.

No failures.

Great drives for the Synology NAS DS220+. Have a good warranty and are designed to be used with a NAS.

The drive is louder than I would like. I tend to have a fan running most of the time, so I dont really notice, but when I dont it makes clickity access sound, nearly constantly. Sometimes it seems to never stop. It is not broken, just on the noisy side. My last internal was not like this, so I am a bit surprised that it sounds a bit...loud.

you can count on them in your NAS.

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.
