If you pick something that doesn't fail under their extreme circumstances, it's a lot less likely to fail at home.
That depends entirely on the failure mechanism. If their drives are running hot for very long periods of time and you have very well ventilated case in comparison then the extreme test may not be very relevant. Conversely if there's a drive prone to failure from frequently powering up and down then their results from running 24/7/365 wouldn't pick it up.
Consider the conditions - this is selecting for the environment of a lot of drives packed into poorly ventilated cases so those that cope best with heat will win. While heat over time is a common cause of drive failure there are others, so the results are not so useful for drives in desktop cases or in well ventilated servers (eg. ones with hot-swap bays so there is no way to pack the drives in as densely as Backblaze do).
Anyone around long enough will remember how stupid the CNG trend was
All the busses and most of the taxis run off it where I live. The taxis that do not are hybrid electric cars however.
Hydrogen does directly compete with electric cars and is not competing very well but it is still too early to dismiss it out of hand. Batteries suck a vast amount less than they used to but they are still disappointing.
it always seemed to me that hydrogen powered car were quietly promoted by big oil as they knew they would never be adopted but did help shift the focus and money away from EVs.
While very likely that's only a segment of the hydrogen vehicle work. Also don't dismiss it out of hand just because of the sponsor - the first working hybrid car I saw was built for a mining company in 1986. They wanted a crew transport vehicle to operate underground without emissions and also drive above ground where emissions did not matter as much. Full electric wasn't an attractive option because batteries really sucked an incredible amount in 1986.
There's been a lot of work on storing and retrieving hydrogen from solid storage over the last couple of decades - so if you don't think of it that way and instead think of it as just a gas bottle the numbers would indeed make zero sense. I think "New Scientist" had had a few good articles on it over the years.
Fairly close to highway speed so not bad for a first model. Also remember that the entire point of these things (despite others attempting to bring in their cause) is to reduce pollution at the point where the vehicle is. It's a car for city driving. The pollution is mostly shifted to heavy industrial areas instead of where a lot of people are trying to breath. There is also a bit of a fuel security aspect where the hydrogen can come from whatever source you have around. The Chinese market could really go for something like this due to high levels of pollution from vehicles in their cities. Los Angeles not so much until the things can cruise at 100km/h (60mph).
I suggest reading a bit of stuff on the Harford web site to get some perspective about what is reusable and what is not.
If you are impatient the short answer is that most things bombarded with neutrons become low level nuclear waste that is not active enough to ever use for fuel. It still has to be disposed of in some way - not a difficult problem, but just an example that the wave the magic wand idea of reusing everything as fuel is a simple and misleading "lie to children".
If you want to discuss at a more than grade school level then such oversimplication should be avoided. Sadly PR firms deliberately drove the discussion down to a grade school level and people with a typical level of science education do not know any better.
So who kicks off the safety rating stuff? You really should have thought of that and a pile of other stuff before posting. Even the ASTM was kickstarted by government.
exposed spinning blades of death! And yet, I managed to get into adulthood with ten fingers and ten toes!
They used to be a lot more exposed than you seem to remember. Ask someone over fifty. Also "nanny state"? Am I missing sarcasm or are you really that out of touch with reality. Take a look at Iran if you want to see what a stifling "nanny state" looks like.
Enron was why they "can't have nice things". I worked for an energy utility outside of the USA at the time when that international laughing stock was showing what some people will do when they are not carefully watched. Maybe the regulation went too far, I do not know, but it's there for a reason.
George Washington with help from others managed to do it before he died.
WTF is it with these "tyranny of the masses" idiots? They have no idea how lucky they are to be born into a country where they get some say in how it is run and seem to want some sort of King instead.
The thick copper wire required for 5V unfortunately removes the "easy". Wiring up 12V lighting was bad enough with 100W or so per bulb. Ohm didn't just have a guideline, it's a law. If you want to shove a lot of power down a line at 5V you start to need a lot of copper.
I never got why we never bothered making additional DC sockets for our homes
Why? Wiring the size of knitting needles to feed multiple things that may need to collectively draw a fair bit of current. DC is a bit of a pain for long runs, hence the "wall warts". It doesn't help that there are 5V, 12V, 18V and other devices. If everything was 12V it would make sense (eg. boats wired up with all 12V appliances are apparently a commonplace thing), with 5V maybe a bit less sense unless everything DC is low current like the USB chargers are now. The wiring for 5V DC has to be significantly thicker than for 12V DC for the same power consumption.
I guess you could in theory have a power socket that allows USB too.
Thankfully that is starting to happen with USB on power boards and so many tablets, phones etc charging off USB.
Back in the day hospitals were full of lawnmower injuries until consumers got annoyed enough to tell governments to force lawnmower manufacturers to change their designs. Government regulation is often a "choice of consumers" as well. In a competitive market sometimes all manufacturers of a product sometimes make something the customer does not want because that's what everyone else is making. Without minimum standards you end up with 1980s Chinese quality and safety features.
Glass is very stable over centuries so long as you don't get it wet. Water attacks it very slowly but will eventually leach it away - hence the fuss about vitirification of nuclear waste and some proposed storage sites being too wet. The stuff about church windows flowing over time is "chinese whispers" about lead organ pipes somehow getting confused with glass, then attempted justification after the fact because glazier put the stronger thick edge at the bottom. You need low end oven temperatures for glass to flow over a timeframe of centuries.
If we've learned anything from the Arab Spring it's that most of the people living there favor these types of religiously oppressive governments
A lack of freedom of assembly for reasons other than worship is why they can't have nice things. To put things simply nobody but the Islamist political groups can even meet let alone get organized.
Why do people think it's a democracy in Iran? Ahmedinajad and the others have been figureheads and never allowed to decide anything important. That's why his rants about Israel were not much to worry about, sabre ratting for the sake of popular support with no way he could follow through. It should be taken no more seriously than if the Mayor of Springfield threatened to invade France.
The man is legitimately popular and he has Morality Police on the streets, with the full support of the people who voted for him. It can happen here, people.
You haven't had your balls squeezed by the TSA yet? They are a populist measure that is functionally equivalent.
The Shah was a monster and Khomeni was an unknown quantity with zero blood on his hands at the time so a lot of people were "fooled". The revolution was almost bloodless. What happened next was not.
Just wait a bit longer for the kids to grow up and the loosening grip to let go. Which way it's going to go is a mystery but it's not going to be the stifling autocratic nanny state it is now.
Just in case of thin skins - the comment at the bottom was a general statement describing the hate preachers of Christianity-Lite and not aimed at the above poster.
Disagree if you wish but it's an opinion so debating it as if a fact is pointless.
That's kind of funny since the refusal to accept that humans evolved is about sticking to Dogma designed to keep evangelicals in The Party. Other branches of Christianity that do not rely on a God that does what he is told to do are not threatened by talk of evolution.
If talk of reality is a danger to your God then it is indeed a puny God.

Correct me if I am wrong, but aren't the Toshiba drives still just rebadged Hitachi drives?

Having the vehicle not fall to pieces due to hydrogen embrittlement, also an issue.
That's a very well known issue solved by material selection.
Messing it up would be equivalent to making an umbrella out of sugar.

Yes but that was 1970. New ones are minor.

Already happened and not going to be hastened by minor changes.
