It's about hitting the disk in alternating sections. If you use large stripes (say 16 MB) and a bit of buffering (not a problem with linear access) you will only lose a little speed from the extra seeks. The average throughput however stays the same... which seems important to you.
Why come up with stupid problem with trivial solutions? They are rated for 300G, will they fail any way with bad transit? Yes. Often? Probably not. Just keep a temporary local copy of every backup. After the drives get plugged into the remote MAID they get checked, if something went wrong, make a new copy and try again.
I'm not saying designing such a system makes sense, tape is a mature system... and if the data really needs to be available fast enough to justify a remote MAID you can probably pay for fiber to it as well. Regardless, most of the FUD thrown up against HDs is silly.
If it's really important to you... make a lot of partitions, RAID0 the lot of them... hey presto, a volume which will maintain average linear read and write speed across the entire volume.
Weight and volume wise HDs are in the same region as tapes, so yeah... it would be perfectly possible to design a HD carrier to which you could backup over SAN and then move to remote "storage" (data needs to be kept alive, so the remote storage would need to be a MAID system).
Wealth concentration kills the economy... there is no value in a factory which produces goods for which there are no consumers, and consumption is only dependent on income for poor and middle class people. So yes, market value has been destroyed.
The casino is always trying to rip you off, but in this case it's probably just the normal rip off and a machine failure.
That couple should put up a web page of exactly what happened with the name of the casino mentioned as many times as possible and in big letters at the top... with a bit of luck the casino will pay them to take it down.
Well unless you have brown skin, in which case you are effectively forced to always have identification on you (unless you want to spend time in jail if the police ever stops you for any reason).

Intentionally writing story lines which only give the appearance of order but which are actually just random shit happening is smart? I'll freely admit, it was funny when I saw it the first time in Twin Peaks... but I just can't stomach DEEP any more. It's not smart, it's lazy at best and pandering to the lowest common denominator at worst.
The patent legal industry does have the habit of pushing it's opinion on patent legislation while pretending to be impartial... which is either evil or extremely naive.
What is especially grating is that they then turn around and tell engineers they aren't allowed to judge obviousness because they are biased by hindsight (and thus we have to use lawyer written "tests" which just pervert the meaning of the word and turns obviousness into a question of prior art).
There's always ambulance chasers like Intellectual Ventures... they will of course take a huge percentage, but that just goes back to lawyers being the only ones coming out purely ahead in this game.
It's always been my opinion that projects like xvid and x264 should have a "may not be distributed in the United States" (and now also Germany) in the license. For something like Linux and GCC you might have a case when you say "well there are patents, but they aren't being litigated so who knows if they are valid" but for MPEG some of the patents are known to be litigated and known to have been declared valid in court.
Any copying being done for American (and now German) recipients for these projects is not authorized by virtue of the GPL... if you can not can not provide the rights which come with the GPL then the GPL does not grant you the right to distribute. The project owners are really subverting the GPL by pretending that's not true.
Small inventors who want to work on stuff they can't bring to market by themselves do benefit, because without patents it's very hard for them to get money together in secrecy to get a lead on the market. That said, the damage it does to small (software) engineering companies by making any little project they do trip over a dozen of patents means it still is not worth it.
As for big companies, they might benefit from being able to throw up barriers to entry... but slowly but surely it's becoming apparent that "it protects the big guys" was just a way the lawyers used to sell it to the big companies. Being able to throw up patent walls doesn't protect you from being bled dry by patent trolls.
In the end there is only one group who benefits from patents and suffers no negative results... lawyers.
Gearing affects force, not power... so if gearing could cause the control motor to need to be "more powerful" it could cause it to need to be less powerful as well. AFAICS it can do neither though.
It seems the variable speed control always has to provide half the output power... even if you chain multiple magic gearboxes. Still that halves the power necessary for the true CVT, might be worth it.
The presenter in the video claims the energy needed to vary the speed on the second shaft is very small, compared to the input power, so you can use a small electric engine.
Spun down HD takes less than 1 Watt, Atom or low clocked Athlon server ~20 Watt, if you use RAID1(0) you really don't need hardware RAID either... so why would this take a lot of hardware/power? An union of RAID1 arrays with a dozen drives where only 1 of the arrays is spun up takes less power than a 4 drive RAID5 array.

You can't transition to a post scarcity economy at all without heavy wealth redistribution.
Otherwise the economy tears itself apart in the transition, which is where we are now.

Modern cheap SATA drives have average linear read and write speeds of around 120 MB/s.

The German court used TRIPS in their argument for why software patents should be legal BTW.

Smart people can make very dumb choices in life (or more often, avoid making choices as much as possible).
No matter how well explored the metagame in a RTS gets I doubt you can be among the best without a high IQ.

It's not like there aren't other licenses they could pick which try a little harder to be patent compatible.

The idea doesn't seem entirely new (and I'm not convinced it works).

Has a limited number of client connections though (10 I think). Not a problem for most, but annoying.
