Western Digital Announces World's First 10TB Helium-Filled Hard Drive (techgage.com)
Deathspawner writes: Western Digital today announced a new, helium-filled enterprise HDD that allows for 10TB capacities without using the SMR method, sticking to industry standard PMR. SMR, or Shingled Magnetic Recording drives, can not typically be used natively by the OS or disk controllers, and instead often require extra software and/or firmware updates. This makes their broad adoption limited, since the drives are not drop-in replacements for the far more ubiquitous Perpendicular Magnetic Recording (PMR). WD's latest enterprise drive, sold as the HGST Ultrastar He10, uses the PMR storage method, and as such is a full drop-in replacement for any standard hard drive.
All the audio tracks you store on the drive sound really high-pitched and squeaky when you play them back...
I've abandoned my search for truth; now I'm just looking for some useful delusions.
Tethering yourself to a bunch of helium-filled drives is a great way to get into the cloud.
Thanks to the War on Drugs, it's easier to buy meth than it is to buy cold medicine!
Soon my pr0n will fit on a reasonable number of drives.
We keep finding new uses for Helium, but not new supplies.
Doesn't helium leak out of things shockingly quickly? What's the expected lifetime of the helium within the drive, and when will it stop operating with... whatever helium adds to the equation, here?
I have an SMR 8TB Seagate drive which is marked as an archival drive. It's worked well so far. The problem with Shingle Magnetic Recording drives which I have noticed is that occasionally the drive will "stall" while it rearranges data. This is probably extremely bad for some raid systems as the paranoid ones might think the drive has prematurely died. Still this drive was inexpensive for its size and stores a LOT of data which is handy for backing up my actual RAID NAS system. Just don't use a drive like this in your Raid or you might run into serious problems.
I worry about these helium drives leaking their helium eventually and dying. They claim to have a sealed unit where the seal will last for years which is hopefully the case but you never know...
But I've got some helium-filled drives, and the mechanical noises from head movement etc are actually distinctively different and higher-pitched.
Western digital announces that the new hard drives use the integrated face system to store data.
Lighter laptops. Great news
Should be easier on batteries too right?
What to do with dead HDD's, suck the air err helium out!
We all end up with a dead drive sooner or later. But don't throw it out! Open that fucker and remove the arms. Ha ha! You can't, can you? They're held in place by mental magnets. Get yourself some kind of leverage tool and prise those cunts apart. Ta da! You now have a pair of ridiculously power magnets.
The trade-offs are too great. HAMR will hopefully be viable soon.
Must be anti-cylon design. Battlestar use Only.

I agree that Hydrogen sounds like a better approach.
1) orders of magnitudes cheaper
2) even less dense
3) much larger molecules, so leakage should be far less
Not inert, true, but that should be possible to deal with.
I love Mondays. On a Monday, anything is possible.
"SMR, or Shingled Magnetic Recording drives, can not typically be used natively by the OS or disk controllers, and instead often require extra software and/or firmware updates"
Only host-managed are that way. There are device managed drives as well.
Is there any data to show that "typically" many SMR drives are host-based instead of drive-based?

Nice thought on #2, but incorrect. Hydrogen diffuses through steel quite quickly.
Hydrogen is the bane of ultra-high vacuum (UHV) systems, which have stainless steel walls 1/2 to 1 inch in thickness. New system? Hydrogen comes out of the steel itself, as it contains some. But with time, that might be depleted, but no —more comes in from the atmosphere, or from any replaced components or new seals.
For UHV systems, helium is quite useful for finding leaks. Microscopic or even nanoscopic pathways for the helium atoms to make their way in. One frequently has poor base vacuum, and must hunt around blowing helium on suspected parts. These could be anything: micro-crack in a weld, stress-crack in a feed-through, an improperly bolted seal, a loose bolt. It can get very fiddly.
Longevity on these will suck, Helium seeps out of everything eventually. so these drives will not just fail for normal reasons but instead fail due to helium leaking out and drawing in standard atmosphere.
Do not look at laser with remaining good eye.
The permeation rate of helium is roughly:
diffusion rate of seal material / thickness of material * time * pressure difference
The pressure difference term can be made approximately zero using a diaphragm to allow for changes in atmospheric pressure. Any value * 0 = 0, so permeation (leakage) is roughly zero.
Additionally, some seal materials work quite well. But again that's easy when the inside and outside are the same pressure - there's nothing causing the helium to exit, even if it could pass through easily.
There's so little space inside a drive to fill, I don't think cost of the gas itself would change by more than a few pennies.

So why not vacuum?
Is it much harder to achieve UHV than filling the cavity with inert gas?
4wdloop
And why is your voice so funny?
The reason will be the pressure differential. With vacuum inside, a drive's housing would have to be much stronger. Read: thicker, bulkier, heavier, more expensive, and leaving less room inside for platters / heads etc.
By US government edict, these drives cannot be exported to 1930s Germany. We instead recommend our Hydrogen line of Flash drives.
The real reason is that the heads need some medium to "fly" on. When they rub the disk surface, it's called a crash for a reason.
Why guess when you can know? Measure!
The drive heads rely on gas in the drive to work correctly.
I love it when the head rubs the disk surface...
wait, what were we talking about?
The GP didn't say that we're running out of He; the GP said that we are not finding *new* supplies -- which is not something you refuted. You quoted something about known supplies. It could well be that the GP's claim is true. Most of our *new* natural gas supplies are from fracking, which results in very little helium.
Moreover, I'm not sure what you're trying to prove. You note that, "*A few* fields in the United States contain over 7% helium by volume," and then make the unsubstantiated claim that none of this He is recovered (which, if true, would prove what, exactly?) and that these few fields contain more than enough He for everyone. Citations please! The fact is that He prices are going up, and Econ 101 says the cause is demand increasing faster than supply.
Hydrogen would also provide a super-cool secure erase facility! And most excellent data center fires :-o.
Yeah, I guess the amount of hydrogen would be quite small..
Did Hitachi release a swingin song about Shingled Magnetic Recording? The Perpendicular one was great!
I thought 8 and 10tb helium-filled drives had been around for a while. Like a year or so.
If you can have one backup drive to have to manage an offsite variant off, that is already far better than two.
"There is more worth loving than we have strength to love." - Brian Jay Stanley
The Magnetic Technology Failure Board investigates head crashes and assigns blame to procedures and operators, much like the NTSB.
FYI the HAMR road map is SMR.
Perhaps there will be non-SMR version as well.

I was thinking about that. "Gee, let's put a flammable gas inside something that can get really hot! What could possibly go wrong?"
However, Hydrogen has a pretty high auto-ignition temperature (over 900 degrees F), so your computer would have probably melted into slag long before your hard drive exploded.

True, but figure it's a data center so you have a whole lot of them. Of course, they wouldn't all go up at once, so you'd have more of a pop-pop-pop than a big kaboom.
Wrong. Diffusion depends on the PARTIAL pressure difference of the helium. For helium at one atmosphere on one side, and the atmosphere itself on the other side, the partial pressure difference is one full atmosphere.
drive heads use Bernoulli's principle to 'fly' an incredibly small distance above the platter. Take the gaseous medium out, and you end up with a record needle instead of a magnetic read / write head.

To be clear: most people buying these types of drives don't buy them one at a time to be shoved into a workstation, or even to be used as a backup. They buy 10+ or more at a time to assemble into some sort of RAID. They are most likely looking to maximize available terabytes per rack unit in a datacenter. Things like cost are secondary in these scenarios -- it costs what it costs. 7200RPM is great, especially when a large number of drives are striped together with RAID 10 or something similar (because with RAID 10, the more drives you add, the faster things go). Latency? Meh, we'll front-end the array with a nice SSD-based read-write cache (also RAID10), usually one that's managed right from the same controller card. And like most new enterprise-class drives, these have SAS3 interfaces -- that's 12 Gb/S. With arrays built with these drives, your network bandwidth and OS offload likely become the bottleneck very quickly. Make no mistake -- the target buyer is someone who wants to build very dense, fast, large arrays of drives -- think JBOD for virtualization, or a huge fast fileshare box with a bunch of fast NICs, or a big database instance, etc. So -- until SSDs come in these capacities -- just because *you* won't use this in your gamer rig / IDE / whatever, doesn't mean there isn't a market for huge, relatively fast spinning rust drives.
Soon my pr0n will fit on a reasonable number of drives.
And your g1rlfriends will fit in a similarly theoretical space.
Thanks for that.
Sure it isn't the other way around. Let me quote wikipedia https://en.wikipedia.org/wiki/....
Oxygen.
2) even less dense

We can solve this by making the cases out of hydrogen!
So if you happen to not find your HDs, look at the ceiling
Slashdot, fix the reply notifications... You won't get away with it...
Hard Disk Drives are so obsolete. This is like Atlanta Coach Works announcing their latest, greatest, horse drawn buggy. It is lower, longer, wider and has ... SSD is the answer.
more chrome than their 2015 model. Has gas shocks in the suspension, and electric whips for the horses. But still a buggy. I'd rather drive my car.

A helium "molecule" is just a single helium atom. It's .31 Angtsroms. Much smaller than a hydrogen molecule.
The comments about hydrogen and steel not getting along, though, are pretty devastating.
The post says:
> Shingled Magnetic Recording drives, can not typically be used natively by the OS
but gives no reference or explanation for this claim. Searching for this claim finds it repeated verbatim on many sites, but no explanation.
The details of the recording technology rarely matter to the OS which treats the device as block-level storage. I'm not saying it's impossible for SMR to require an OS update, but I would like an explanation or reference.
It sounds like problem is that an SMR drive can't write to a single track, so using it *efficiently* requires an OS update, much like SSDs. But some clarification would be nice.
No, she'll still be big.
