6TB Helium-Filled Hard Drives

Would be interesting to see how they intend on keeping that Helium gas inside the drives, because it is a bitch to contain.

What would happen if the helium were to escape? won't that just create an extra point of failure in exchange for extra storage on one drive?

most likly to do with friction and heat ...

 

guessing its sorta the same reason race cars use nitrogen to fill there tyre's

 

Nitrogen dont help by himself is because of the tyres.

with that high count of bits per sqare-milimeter data probably won't last that long.. and getting these drives to be pressurized with helium over a long time will be pretty expensive as helium can escape through thin metal and rubber over time (helum-molecules are just tiny enough)

Woo because hey, we're not already running out of helium...

 

Some guy on the Ars Technica comment section of this article says;

For anybody concerned about the helium consumption of these drives, I did some numbers (which I've only nominally checked, so feel free to correct me if I made any mistakes):

Quote:
A 3.5" hard drive's external dimensions are roughly:

10cm x 15cm x 2.5cm

HDD volume:

375cc

Internal airspace, estimated less than 190cc

A standard 12-inch balloon occupies 15000cc

At least 200 12-inch balloons can be filled from a standard 125 cf (medium-sized) helium tank (costs about $80 to rent, which gives you the helium inside plus the overhead of renting it)

Hard drives per helium tank: 15000*200/190 = 16,000

Helium cost per hard drive: 0.5 cents

Helium would need to rise to 200x its current price to comprise $1 of the hard drive's manufacturing cost

Roughly 700 million hard drives are manufactured each year; if they were *all* 3.5" (unlikely) and *all* helium-filed, you'd need 50,000 of those helium tanks to fill them.

200 million cubic meters of helium are produced/extracted each year, meaning our 700 million hard drives would consume 133,000 cubic meters - 0.07% of yearly production.

In short, I don't think helium filled hard drives are going to have much of an impact on our helium reserves either way.

So, if his math is correct, then our helium supply isn't going to run out because of these hard drives.

So we can't make artificial helium? What's the big deal, people not getting high off helium due to it being in low quantities really that bad? Maybe we should sacrifice helium balloon's for helium drives and call it a day?

I roll with sigs off so I have no idea what you're advertising.

 

This is NOT the signature you are looking for.

why not make vacuum sealed hdd's?  wouldn't that be better than using 2He

Wow I had no idea there was a helium problem until this thread...

 

 

Fortunately, there's a backup plan: If we run out of mined helium we can always recover it from the atmosphere. That will run us only 10,000 times the current costs.

Sorry to tell you, but already been posted. Search function works wonders ;)

Search function is broken to all hell and back. 'Google does wonders' is more appropriate

Agreed :)

that way no air no resistance whatsoever.....just a thought!   :)

 

Well lets leave it as a thought, as you know you can't build a perpetual motion machine, at least not on earth.

Doubt that you need much to fill a HDD.

The same amount used to cool a super magnet for a few minutes could probably make a ton of HDDs.

I think fusion nuclear power could be used to create helium as well, so one more reason to research that.
