This is purely subjective as all enterprise class hdd have similar technical specifications & they all use identical manufacturing process. Unlike consumer class drives where there have been infamous examples of initial WD green models & certain seagate barracuda 7200.10/DM2000/DM3000 series models in 2011-2015 there has never been a "mass failure series" in enterprise class models in last 10-12 years as far as I know.

exactly, some people prefer WD's some prefer Seagate's and they always will, but all enterprise-class drives are pretty much good regardless of the brand, they are built for durability. We see a lot more Seagate than WD-branded drives in the enterprise-class, before selling drives, I use to not like Seagate drives, as I had some of their older models fail on me back in the day, after which I exclusively stuck to WD. now after selling Seagate drives, my inclination has shifted again so much so that I am now personally using all Seagate EXOS drives on my system and only have 1 WD RED drive.

This is positive info:)

Yes, I've heard of this, but it's a scam or a fraud when the seller is selling these drives as new. and almost everyone talks about buying new and getting used models or older models *which they returned for a refund*
The troubling part is the smart data being altered there , strictly talking about that particular case

Just fyi, genuine "manufacturer recertified drives" (not seller refurbished or this particular case) also have their SMART data reset but that is done by the manufacturer itself after deciding that current SMART data is negligible to affect it in the long term.
 
"If the drive passes a stress test like pre-clear and post read on unraid, it will probably last a long time."
I have belived this for a while. Am I wrong or not getting some nuance?

It is "decently" correct if you keep in mind this golden rule that any hdd/ssd can fail at any time as no hdd/ssd is 100% failure proof. Also, it is a good idea to start thinking about replacing hdd/creating backup (if required) when it crosses 50k power on hours.
 
The 20 x 16TB lot has arrived, this one was a huge mess, will explain it in detail later. currently testing the drives will go on sale on Monday, I don't know the final pricing yet either so please don't DM and ask me, I will know once I receive all invoices from the logistics team.


As per the article, it seems that CrystalDiskInfo should be fine to use and I will include a photo from that alongside of HDD Sentinel
Below is a quick health info of one of the drives that was open by the customs dept.

That is fine for "non-tempered" drives but for the "tempered drives" one needs to check using tools like below which compare a "certain seagate official firmware value" with power on values seen in typical SMART based software like hdtune & crystaldiskinfo to see if they match (or very closely match) or not.

 
Seagate 16TB EXOS
Model:
Power On Hours: 0
Start Stop Count: 1
Qty: 20

Pricing: Rs. 18000/-

Smart Data: https://drive.google.com/drive/folders/1DTkhAR92raG4QUd7qow6y323Hqz5p7Y_?usp=sharing

RANT: last time when I ordered 20 qty of 14 TB & 16 TB drives (10 of each) they did not attract any additional scrutiny from the customs officials last time. but this time the order was withheld for 5 days, while they opened the package and checked the drives. They came back with the usual, that the package is undervalued and to show proof of purchase, but also something new was that this required BIS certification, and that to release them, since the quantity was high, they would charge me Rs. 2000/- per drive (in total Rs. 40000/-) :eek:
my rebuttal was very simple, I told them I was ok declaring the full value of the drives and showing the full purchase invoice because if I did that and went through the official channels my customs duty/GST would not be more than 40k they were asking me as a bribe. they said but you still need a BIS cert to clear it. I did a quick Google search and found out that there is no mention of BIS certification for the internal hard drives only external USB-powered drives are mentioned, I showed them that as proof and they backed off, but I still had to pay for the undervalued item and the amount agreed on was Rs. 1000 per drive. which increases my costs to acquire them and therefore increases the pricing above. I wanted to price it at the same pricing as last time but with additional payment made, ruined that chance.
That is fine for "non-tempered" drives but for the "tempered drives" one needs to check using tools like below which compare a "certain seagate official firmware value" with power on values seen in typical SMART based software like hdtune & crystaldiskinfo to see if they match (or very closely match) or not.

Its difficult to test them in the current scenario, I don't have Linux on my main machine and every other system I have is a Tiny. I tried checking with the external casing I usually use to connect to my PC and no data was shown.
