Hard disk drives are hitting a wall for density in 2019,
thinner gases and platters needed to raise capacity. and
few breakthroughs are forecasted that will raise 3.5
capacity to 40TB and beyond.
Then I thought, why not take the size of the first hard
drives and put todays
densities on them, we could have
a washing machine sized hard drive in the exabytes.
realized the R&D, Factory Tooling & RPMs for such drives
would make it an hard sell to datacenters with slow read
So I realized, why has nobody proposed to double / triple
quadruple the height of a 3.5 HDD to fit more platters
inside? By making the drive housing multiples thicker of a
standard drive, you can at
least double the HD data capacity with todays mature
This way, the HD only needs one write arm, one motor,
interface board, one set of SATA ports and one housing to
multiply the capacity of a hard drive. It
would need minimal R&D, tooling, for the read/write
head, spindle and housing manufacture. The drive might
cost twice as much to make but have 5 times the
capacity as you are using the high precision parts of the
drive for 5 times the platters.
They could make a drive five standard drives thick,
about as tall as it is
and have 6x the platters compared to 5 seperate HDs.
This Sextuple HD could store a
100 TB and sell for $300 retail in 2019, and the company
that made it could make
digit profit margins.
Datacenters would gobble this up as the cost per
is a fraction of the price compared to buying multiple
standard HDs. Even if half as reliable as standard HDs
would gobble it up due to the sheer reduction in storage
Prosumers benefit too, imagine being Linus Tech Tips
creating a TB a day in raw 12k video footage. Imagine
buying a 100 TB hard drive for $300 in 2019!
My digital life is less than 10TB, but I would love buying
Triple HDs because I could store every MB I have on one
drive, and carry it like a lunch box with over 20TB to
I nearly kept this to myself to patent it, but I realized
would make me & lots of people richer if it got on the
market soon. So Im posting it so someone can convince
WD, Seagate or HGST to give it a chance on the market.

||// slow read / write speeds.//
||Just RAID your large drive for better speed.
||I think the likelihood of SSD prices dropping to be the
same as HD prices going to dissuade anyone from
investing in new HD technology
||Big note of caution for SSD. Depending on your supplier they have different failure modes - either total brick or recoverable. It was a big brand name on my 2nd iteration of drives that bricked itself.
||To recover SSD's just get it into the BIOS and leave it for 30 minutes to sort itself out without any hassle. My first set sprang to life again. Big expensive brand - bricked - it was in the specs all along.
||HDDs are so cheap these days I don't know why computers don't come with an automatic backup HDD (also known as RAID 1) as the default. This should mitigate any concerns about HDD crashing/bricking, since the chances of both HDD crashing at the same time are tiny (unless of course the HDD crash is caused by dropping the computer).
||Who needs drives? Just store it in the cloud! 😎
||Seemingly many milennia ago, but actually only in the mid-1980's, the IBM PC-XT came equipped with a 10Mb 5.25" "full height" MFM hard disk drive.
||Physically, this was the same form factor as two typical DVD drives placed on on another. These drives were extraordinarily fragile, consumed huge amounts of energy, were only slightly faster than Edison waxed cylinders in terms of access time, and cost as much as a small car. They were also highly desireable, meaning that they were usually allocated to managers where their potential as computing devices was wasted.
||A quick test indicated that one of these drives would occupy the same volume as about 8 2.5" HDDs placed "on edge" with space for a fan and some auxiliary electronics, so upgrading an XT with 640Kb of RAM and a 4.77MHz processor with an additional 16Tb of drive space would be an interesting project; getting MSDOS 3.3 to address that much capacity would be a challenge.
||I have an uncomfortable feeling about blindly putting all my data on "the cloud". Call me old fashioned if you will ...
||[norm], you're old-fashioned.
||Putting things on edge makes a difference to the
||No, but it allows better conformity to the dimensions of the larger drive.
||Just find yourself a reasonably good Mentat?
||Just make sure he's RLL encoded. (Red-Lipped Logician?)
