"As of June 30, 2020, Backblaze had 142,630 spinning hard drives in our
cloud storage ecosystem spread across four data centers. Of that number,
there were 2,271 boot drives and 140,059 data drives. This review looks
at the Q2 2020 and lifetime hard drive failure rates of the data drive
models currently in operation in our data centers and provides a handful
of insights and observations along the way. As always, we look forward
to your comments."

"At the end of Q2 2020, Backblaze was using 140,059 hard drives to store
customer data. For our evaluation we remove from consideration those
drive models for which we did not have at least 60 drives (see why
below). This leaves us with 139,867 hard drives in our review. The table
below covers what happened in Q2 2020."

Yup, buy HGST drives. And hard drives are getting more reliable.

Go off the median skew, low cost consumer Western Digital and Seagate,
and there will be added cost. Probably at "enterprise" offerings,
additionally, for such as the above, which equates to perhaps longer
warrantees than a commercially-skewed drive, whose ratings may apt
favor in-house IT reputability, over term/unit-replacement
considerations. Bottom line is still a shared gamble on failure for
either.

Also, a deal that goes down on cloud facility material demand, a bid
to manufacturing is unlikely to resemble how the manufacturer,
themself, represent their product line. Samsung and their QVO,
various EVO model offerings, for instance, are no less prone to
customized manufacturing runs -- unusual configurations resulting from
two groups of engineers getting together, Samsung's and a prospective
buyer's engineering interests, together who bid/counter-bid for
specific specifications and concessions.

I was looking at one from perhaps a laptop brand, accordingly to how
deep they want to go into stressing quality. I'd found a Samsung SSD
with an off-the-wall serial nomenclature, spares in eventually being
sold on EBAY, at some premium for Samsung quality. What they actually
were are Samsung drives that came up in excess and didn't make it into
a production run for a customer Samsung made these drives. It would
probably take a x60 magnifier after splitting that particular case to
determine where component materials were sourced for applicability
characteristics.

What's the best place to buy new ones for cheap?

Let's take a random advert.

https://www.serversupply.com/HARD%20...ST/0F38462.htm

HGST is owned by Western Digital.

The category is "Enterprise". 16TB for $577 USD.

HGST was staffed by IBM staffers, because it was
the former IBM consumer drive division, and made
DeathStars.

They might have done HelioSeal before WDC did.
Unlike regular air-breathing drives (which use a breather hole),
the HelioSeal are sealed and have a Helium gas atmosphere
inside. Helium drives draw less power, or allow more platters
(with the platters eventually returning to glass, just like
IBM days - that's how they plan to make thinner platters).

The Helium gas is guaranteed to stay inside for 5 years.

What part of that history sez "16TB for $79" ? :-)

Whatever the guy in IT, on the inside of big volume
corporate/government dealings, tells you to buy. If you're lucky
enough to know one less hard of hearing than dispensing spare time.
Cheap is as you will. I once found myself undisputedly clueless, upon
attending a semi-private procurement event, how so many corrupt and
decadent people conceivably all fit into that one room at the same
time.

Glass? Maybe OK for hoop stress at 10krpm (1.8 MPa / 260 psi)
but you might want to be careful with the jerk at spinup.

The Helium gas is guaranteed to stay inside for 5 years.

Why not Hydrogen? _Much_ cheaper and better properties.
Oh, yeah, invokes the LZ Hindenburg at the hands of Joisey
longshoremen (What are grounding strap?) But seriously, the
heat from that small a volume is less than in a cup of coffee.

Balloons should not be filled with pure hydrogen unless you are
real careful or making YouTube videobangs. In large numbers
they'd be a hazard especially with the static electricity.
Nor does Nitrogen dilution help much.

I don't think hydrogen is quite as good for the
metals around it. Helium has fewer "side-effects".

As for the glass, we don't know what kind of glass
those platters are made from. I guess we'll just
have to get one of those $79 drives and open it up
for a look. They love the exotic chemistry, so just
about anything is possible. The surface finish has
to be smooth to about 2nm or so (at least, that's what
the MFM pictures look like, of the surface).

Does anybody have a Helium drive more than 5 years old? They arrived 2013 IIRR.
