MIT boffin: Salted disks hold SIX TIMES more data
A Singapore researcher claims that disk drives could hold six times more data by adding table salt to a bit-patterned media (BPM) process. This sounds bonkers but there is a pukka press release issued by Singapore’s Agency for Science, Technology and Research (A*STAR) which describes Dr Joel Yang's work. Bit-patterning is a way …

Totally normal
After all, it's like chips, they also taste 6 x better with salt on them!
6 times better? 5.3956, you have to balance it with the guilt of eating too much salt!
Even more amusing
If Intel can apply this process to cpu's.
Really?
#unplugs and opens hard drive#
#sprinkles platters with table salt#
#close and plugs drive back in#
Oie! That didn't work any better than this "water cooling" thing I was told about!
You probably used salt with Iodine. Please try again with salt without Iodine.
(Tablesalt can be bought both with and without as it's a good way of averting certain illnesses)
Re: Really?
If you use the table salt and water cooling together, you will see a drastic change.
@"use the table salt and water cooling together, you will see a drastic change."
... and as an added bonus, you can have a sea life aquarium in your PC.
Keep the fries salted!
Looks like System Shock had it right all along.
Could somebody grab my coat for me? Left it in Beta Grove...

I bet the first commercial one is a sea-gate

It's obvious
Everyone knows you need salt with your chips.
Just think what they will be able to do when they discover the magical properties of vinegar.
Hah!
I had to admit I was wondering if it was an April Fool's come late...
...I mean, imagine it - you can just see a thousand 1st and 2nd line support kiddies around the country all opening up their cases and pouring table salt all over the insides...
Units?
Tbit/in^2?
Come on el reg. Where's yer Libraries of Congress per milliWales conversion?
Yeah, El Reg need to come up with a scale for something this small. Perhaps something based on the Jedward-Talent?
...or even the Beiber-Talent (ducks in case there are any True Beleibers lurking ready to pounce, not likely on El Reg but you never know...)
If only...
..they could increase the size of hard drives as fast as they can increase the size of bloatware, we'd be getting somewhere.
Great Idea...
That looks great, right up to the point that the iron platters rust...
you got it
If you mean disk storage, doubling (or more) the linear density will double the transfer rate assuming the associated controllers and paths can handle it, and I think they can.
If you mean main memory storage, then see last week's article on memristor development with products coming in about a year.
500GB != 3TB
"a 500GB 2.5-inch hard drive could hold 3TB" Uh?
For the obvious:
500GB-sized drive (assuming platter density gains of 6X as per the article) would scale and become a 3TB drive, based soley on same platter size with density gains.
Granted, for those who didn't catch this, the explaination will probably be lost on you as well.
Agreed, but if it's a 500GB drive, it can't be a 3TB as well!
It's a pedantic comment on grammar, not arithmetic.
"table salt"
Seeing that term used to describe actual salt in a tech article confused me so much that I've just sprinkled a load of pseudo-random characters on my chips.....
Now all we need
is for some researchers in Glasgow to invent a deep-fried one.
I think we need someone to write a Research Pepper...
/gets coat and is dragged off stage left.
Overkill?
3.3Gb seems like a colossal jump from 128bit salts
/gets coat.
Wait...
People are still using mechanical drives? Oh oh...is it for slow-access long-term storage units?
Yea but...
The storage density goes up, but future research will reveal that the average disk life declines due to increased risk of heart disease.
<ba dum dum>
So... how can the...
Solid-state HDD Manufactures (ODMs and or OEMs), plain to make their Gear more attractive to the Man on the Street? I mean a 3TB HDD (i.e. Platter Drive), for ca~ 150- € seems to me a more attractive proposition then say a 40GB ~ 60GB SSHD that cost 2x to 4x as much?
And here I thought the Future was in Flash.
Well not at this rate, and I for One welcome our bargain Basement 3TB 2.5" HDDs
This is nonsense.
I soaked my hard drive in salt water and now it won't work!
Despite the salty comments...
The real beneficiary of the increased density won't be 3.5" bulk drives at 20 TB. Look for 1.8" notebook drives replacing 2.5" and 2.5" replacing 3.5". It's worth noting that an array of (enterprise-class?) 1.8" drives will have 3x t0 4x the spindles of 2.5" in a front-access removable configuration, and maybe 6 to 8x in a non-removable bulk store configuration. With a 2x to 4x density gain of 2.5" over 3.5", we'd be looking at 6x the IOPs/U for removable and maybe 32x for non-removable bulk arrays.
That's more than a little interesting, given the IOPS starvation systems are facing without some action.
Big versus small
Either way, you can still cram 4 or more laptop sized hard drives into a single full size drive bay on a desktop computer. That dramatically shrinks the footprint of a storage array that has some hope of meeting modern multimedia storage needs.
Just as always, stories of magnetic tech reaching insurmountable physical limits and now there seems a way to improve it dramatically. You'll never catch me saying `well, that's it for X technology`.
re: Units?
Since nobody was interested in my previous post, I thought I'd make a stab:
1 LoC (Library o' Congress) = ~80 Tb
1 pWa (picoWales) = ~32.2 in^2
Therefore: 3 Tb/in^2 comes out at being a barn-storming 7.5 LoC/pWa
Not bad. If only I knew what it meant.
Can I have a 'P' please Bob...
When I looked at the photos it just reminded me of a very large Blockbusters board...
News just in...
Two hard drives we out on the town last night and the higher caacity one was a salted.
If it can be applied to power
You could get laptops with a saltened battery.
/getscoat
This just in...
Windows 9 will take 1TB of hard disk space. It stores all data as 32 bit characters, UTF-32 and all that. Program binaries take a gigabyte each.
Disk space all taken up, please move along.
"faster"
Higher density gives greater linear throughput.
It does NOT give greater IOPS - seek times stay the same.
Will applying salt to HDD arms reduce their inertia?
It's a PR scam
The fact that it uses e-beam lithography means it's a scam. As anyone who uses e-beam lithography knows, just to lithograph a square centimeter would take a week or so.
And no rusting?
I wonder whether MSG can be used as a cheap substitute.
Heh
When I first scanned the first paragraph and saw (A*STAR) I immediately assumed the "*" had been put there instead of an "S".
It was a WTF moment.
