C'mon $10/TB! Honestly with DDR4 prices finally dropping this year I'm just glad high density drives are falling too.

At same time, curious about longevity of these He drives, as we know He slowly leaks out wondering if the age of 8+ years of use has past

So is that actually a problem problem, or more of a "it may be a problem"? I haven't heard anything along those lines, but I just might be ignorant to it.

I honestly don't know either and was tossing out the question. What I have to go on are articles from HDD makers when tackling the He problem and how they really struggled to contain it. Eventually they got the seal to a point where it was ready for mass production. My curiosity though is around the fact that He can "leak" out of even metal because of how small the atom are so logic says the drives will eventually lose its He?

I think drive prices will continue to drop for sure. The 16TB drives are out now and I see them regularly so as they become prevalent, they will definitely force the prices on the 8TB, et al down for sure.

But the flip side of this is that 1/2/3/4/5/6TB drive prices are going up. I'm seeing 4TB regularly priced where I can buy 8TB. I guess it's a marketing reaction because if you need a 4TB, you're stuck as you can't use anything larger, and now you're going to pay for that. Of course that is just going to drive upgrades to remove the equipment that requires 4TB drives, and then the drive prices will crash when demand crashes, and by that time 4TB ssds can just be used instead and wake up that older equipment since the ssds will be so much faster in the application. As the IT world turns...lol...

Pricing in my experience follows bathtub curve, highest when it's new and shiny, drops before bottoming out when it's "obsolete", then it rises again as "vintage" or "must have for replacement" type of situations

Yep, that's the curve all right. Although, it seems that the 1...6TB drives are priced to fatten the other side of that bathtub curve.

My 8 arrived a yesterday but I didn't have time to work with them until tonight. Came in a big box intended for approximately 24. And tons of padding. I feel I'll be reusing it in the future I think.

Noticed when I put one in my TrueNAS box it reported 7.15TiB disk size vs ~7.27 of a typical 8TB drive and the 'user capacity' was ~7.8TB.
SmartCTL reported 4K physical and 512 logical. But I figure they're formatted as 520b in one way or another. It does report "Type 1 protection" which may be it.

I'm going to go through and use sg_format to see if I can set them back to normal 4Kn or 512e without this.

Update, just needed to do

sg_format --format --size=4096 /dev/da12

and

I see no reason to use 512e in my use-case since I'm working with 4K ashift anyways.

Can SG_format be run from within Windows?

I got five of the 8TB drives today, with manf dates (3) Dec 2015, (1) Jun 2015 (1) Aug 2016. I will run some tests and let you know average run time, total writes and overall health if anyone is curious.
