How does this compare to the $200 12tb WD deal a few days ago? This seems have higher $/TB
I've had good luck with WD drives but this is from last year's Backblaze report:
HGST -- now a division of Western Digital -- continues to have the most reliable drives, with a cumulative AFR of just 0.47%.
Toshiba comes in second at 0.98%.
Seagate brings up the rear this quarter at 2.05% AFR.
WDC (Western Digital) hard drives aren't in the listing. Backblaze doesn't say so, but I suspect it stopped buying WDC drives because it had, far and away, the highest AFR (almost 4%) at the beginning of last year. It brought in some newer models for testing, so maybe it'll be back in a later quarter's results.
It's reasonable to assume that high-capacity drives, being newer, would be less reliable. But that's not always the case.
HGST AFRs are consistent. The 4TB and 12TB (ALE600) drives have equally low 0.44% AFRs. Its N604 12TB model has a slightly higher AFR at 0.48%.
Seagate has two 12TB drive models, and one has half the AFR of the other. Their 10TB is the most reliable (0.74%) and the 16TB drive its least (3.49%) of all the tested drives.
Toshiba's 4TB drive is one of the most reliable, while its 14TB drive is only slightly less so, and is on a par with the better Seagate 12TB drive at 1.06% AFR.
A 7200rpm enterprise drive vs. shucked 5400 retail drive aren't directly comparable in performance and warranty.
Everything is comparable.
Without the ability to analyze slightly differing options, we'd really be limited in making purchases which maximize the ROI.
7200 vs 5400:
Do you need/want the extra speed?
Does it justify the extra $$?
Will the 7200 fail sooner?
Does it justify the extra $$?
3 year vs 5 year warranty:
Will either fail sooner than 5 years? If not, moot point.
If so, does it justify the extra $$?
You don't need to buy expensive drive like this for NVR. I have used much cheaper regular drives for the last three years without a single one failed.
Nvr drives need 24/7 duty but they should spin at 3k is speeds because they write blocks from cache in a regular method and are usually large block writes. I would stay away from desktop drives they are not meant for 24 hour duty and use nvr specific drives or an enterprise drive but the power consumption will likely be 50-100% higher. Many of these shucked drives are slower 5k enterprise drives so they could fit the bill but ymmv.

This seems like a good deal for an additional $80 with 5 year warranty
