"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.

This is the same price that WD site had in BF. WD was still "processing" my order. Cancelled it and ordered through Newegg.
Deal expires 12/17 23:59:59 PST. You have to hurry if you want it. Amazon has not price matched.

$17.5 per terabyte is pretty good for the shuck-less non data hoarders.

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.

Yeah...this drive wouldn't increase my storage capacity at all without significant hardware changes. What a shame. Cheap storage isn't always cheap.

these are fine for desktop use - they're rated for 24/7

another bogus statement - TLER requires a hardware controller, which the avg PC doesn't have... end of story

While you can use a NAS drive on your PC, I don't recommend it under most circumstances. NAS drives, aside from the bad sector marking, are 5400 rpm drives - to save power. (Maybe used as a data drive would be fine.)

Amazon has one for $65 after $15 coupon. Wondering if it's the same model?
