Ultra-High-Density Hard Drives Made With Graphene Store 10x More Data

It means you can accumulate more clutter, which you will never use.

Windows 11 will need it for the OS..................

Any day now for the past 20 years: Batteries that will charge in minutes and hold 100x current capacities; dirt cheap solar panels; and new storage type that will hold a bazillion times more data.

Why the concern about low friction and wear resistance? HDD heads fly over the surface without contacting it.

In 2008, Matthieu Lamelot wrote a piece about Seagate drives:

With a width of less than a hundred nanometers and a thickness of about ten, the head flies above the platter at a speed of up to 15,000 RPM, at a height that’s the equivalent of 40 atoms.

The head/platter operation is like a Boeing 747 flying over the surface of the earth at Mach 800 at less than one centimeter from the ground, while counting every blade of grass and “making fewer than 10 unrecoverable counting errors in an area equivalent to all of Ireland.”

As far as using them for PC’s and laptops, SSD’s are the only way to go IMO.

I wondered if anyone would catch the reference....it took awhile - thanks!

“One BYTE = 8 BITS, so 8 Trillion BITS.”

Correct. I missed that.

Do these drives have multiple levels of data similiar to Blu Ray DVDs?

At that bit density wonder what the transfer rate is. And the track spacing.

Cost per bit of storage must be extremely low even now since so much is stored out there now. And all that byte-gobbling video stuff...

As storage and memory increased in the past new applications became possible e.g. Photos, music, videos.

I wonder what applications are on the horizon that would make use of increasing storage capacity?

I have to think it doesn’t stop with video. Something to do with VR?

I don't think so..................

I am impressed with the technology of mechanical hard drives these past few decades.
Considering the mass production of those things they represent serious precision engineering and manufacturing.

Data retention is serious business and those devices HAVE to always work or you are out of business.

I recently bought a Occulus Quest 2 VR headset.
From what i have noticed during my small time using it is if you want seriously good quality 360 degree video you need BIG TIME memory storage.

At this point, I don’t care much about density. 1TB is enough for me. What I care about is access time. For this reason, I much prefer SSDs and will never go back to magnetic drives again.

As long as you have good backups, you'll be OK. The biggest problem with SSDs IMO, is that too many of their failure modes is completely catastrophic and unrecoverable.

They are also too expensive for my purposes, except for the boot drive (where speed is most needed anyway). I still store my data on HDDs because they are much cheaper, and transfer rates isn't nearly as important for me.

WOW! Even More pr0n Home Movies ... PING!

You can find all the Windows Ping list threads with FR search: just search on keyword "windowspinglist".

Thanks to Red Badger for the ping!

[dayglored]

> That’s a lot of porn.

The pr0n industry has been driving the advances in personal computer technology since the early 90's.

Seriously.

Now the search engines are so good, it is crazy to store info on disks.

At least until TPTB determine that the info you are looking for is 'problematic' in some way.

What ever happened to those crystal cubes (around an inch square, I think) that they said was so promising more than a decade ago?
