back to article 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!

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.

We don't need bigger drives.

We need faster storage.

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?

FAIL

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.

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.

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.

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.

"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.
