"Can I use a NAS hard drive as a regular drive? Many people may ask this question. The answer is YES. You can use it as a regular desktop drive, as long as the interface is in accordance. But there is a problem you should pay attention to: NAS HDDs have TLER technology.
TLER technology allows the drive to mark sectors as bad sectors when it can't access the sectors after continuous attempt for 3-5 seconds. This reduced the failure rate of raid array and improved reliability and stability.
However, if you use NAS hard drive as a regular drive, some sectors may be marked as bad sectors incorrectly. Because common desktop drives without TLER technology usually mark sectors as bad sectors when they can't access the sectors after continuous attempt for 30 seconds to 1 minute."​

Yeah, difference is it's not the Red Plus, which is CMR vs SMR on the Amazon drive.

Amazon has one for $65 after $15 coupon. Wondering if it's the same model.
I did not see that. I show this drive as $84 (essentially the non-coupon price).

No. Not the same model. This one is the Plus with the CMR while the Amazon is a regular one with SMR technology.

They are looking at the NON-plus version on Amazon, which has a $15 coupon. DO NOT get the non-plus version, it is SMR and a completely different drive from this one.

I wouldn't order a western digital for anything
I ordered a few Red Plus from the official WD site for black friday, and half of them have already failed. I'm returning them all. Such a shame, as they were an awesome price.

Quote from Kopite :
Funny I just received this drive 2 hours ago from the order I placed early last week for $75. It took 9 days for UPS/USPS to make a 400 miles journey from Newegg's warehouse. As soon as I powered it up, it made a huge spinning noise, so it must be defective. The packaging was OK but could have been better - it was placed in a thick bubble pocket inside a small box that just fits a 3.5" drive. Already requested for refund, Newegg provided a free return label and no restocking fee. Just need to pack it up and make a trip to UPS store Mad.
I had two bad ones from Amazon in the last month. Third is on the way, hopefully it works.

Pretty much, though I was able to get this shipped & sold by Amazon on Thanksgiving for $68.99.

As others have stated, the Amazon deal is a SMR drive. It will work fine in a single-drive NAS setup but the conventional wisdom is that SMR technology isn't well-suited for multi-drive NAS systems that use certain RAID types and "hybrid" RAID-like technologies like Synology devices have.

Yeah, unfortunately the free shipping option from Newegg is very slow. It took over 1.5 weeks for me to get my order of these drives from Newegg.

Amazon has matched the price... although I think their stock is limited ATM.
