16TB spinning rust is here

Most likely HAMR tech, i think we should avoid those and stick to traditional which is PMR and can support currently up to 12 TB.
Is the reason to avoid them because these disadvantages?

I'd never touch them. Maybe with some 3-way mirror software RAID, but definitely not outside of that.
These are HMB drives.
-
The drives use HAMR (Heat Assisted Magnetic Recording) but according to Seagate they say it at least as reliable as old tech. I read somewhere that they have demonstrated that their HAMR heads have 20 times the required lifespan for industry nearline specs.
They had working drives already in 2015 and have been running drives in production 2017 and 2018 so they've had enough years to iron out any issues. The tech itself is decades old. If it was just on the consumer drives I would have been sceptical but since they put it on their enterprise line, especially for hyperscale use, I think the technology is definitely production ready.

They are HMB drives. (Hold my beer)

And then.... Seagate. Will wait to see if WD follows suit.

WD announced earlier that they are also looking at releasing 16TB drives this year. They use MAMR technology (Microwave Assisted Magnetic Recording) which is also new.
I found out that Toshiba also have 16TB drives on the market but they are using "traditional" tech and have done it by adding a 9th platter instead of 8.

@scottalanmiller what's the general consensus here? Do we not buy Seagate because they fail more? Genuinely curious.

Most companies buy drives from their vendor so they have no control over what drive they are actually buying. They are buying an HPE or Dell drive - manufactured by Seagate, WD, Toshiba etc. Just like they are buying 256GB of HPE RAM - manufactured by Micron, Samsung, Hynix etc.

And there is no data that suggests that Seagate drives fails more than others.
Backblaze have some data that suggests that some Seagate models are more failure prone than other drives on average but they also have data that suggests that other Seagate models have less failure than the average drive.

I think the last set of drive failure data from backblaze showed Seagate as having higher failure rates compared to other brands. Don't have the link handy but you should be able to Google it pretty easily.

Generally avoid them, yes. Big usage shops like BB have had issues with them, and repair shops have advised that they see the failure rates on them in the wild being very high.

My buddy the runs his own tiny shop confirms this. He sees more failed seagate than anything else.

What would be the best brand/model high capacity (8+ TB) SATA hard drive today?

HGST. Owned by Western Digital, but still running their own production lines. They're a little more expensive, but also more reliable. You have to decide if the extra cost is worth the reliability difference.

Ever since those floods several years ago, HDDquality has gone down.

Yeah, and anyone that doesn't believe you just needs to go look at the annual failure rates Backblaze publishes.

Yeah I saw that posted here recently. Man, it is a horror story.

Losing a factory will do that, especially for a market in decline.

Don't they also use primarily consumer grade drives?
