what's in the works for the future of computer data storage I mean we've gone
from 2 gabt to 2 terabytes being a
typical amount of PC storage in less than 20 years a thousandfold increase so
are things just going to keep becoming exponentially more capacitors why don't
we start answering this question with a look at our old friend the mechanical
hard drive already there are a number of
Technologies in the works that will make hard drives more spacious while still
allowing them to fit in that familiar 3 and 1/2 in enclosure hard drive makers
like Seagate and Western Digital are working on Technologies such as shingled
magnetic recording which overlaps data tracks to essentially make them narrower
bit patterned media which can encode one bit of data to just one magnetic grain
instead of a group and heat assisted magnetic recording or hammer
which heats up small areas of the hard disk allowing the magnetic grains
themselves that store the data to be a lot smaller and you can learn more about
hammer in this video here these Technologies are expected to help push
hard drive capacities to 50 terabytes by
the year 2020 wow but aside from changing how
magnetic platter data recording Works manufacturers are also looking at using
more exotic materials hard drives filled with helium instead of good oldfashioned
air are already on the market since
helium is less dense than air there's less fluid resistance when the drive
platters spin meaning more precise positioning of the Reed right head with
lower power consumption and all of this without making your mp3 sound like the
singer just sucked air from a balloon of
course by this point you may have moved off of hard drives in favor of ssds in
which case you might be more interested in Intel and micron's 3D Cross Point
which features very dense Arrangements of memory cells that don't require
transistors leading to higher capacities 3D Cross Point will also have latencies
up to a, times lower than traditional
nand and will last for much longer than a conventional SSD meaning we could see
drives much bigger and faster than what we have today and Samsung is also
working on a competing technology called zand though they're being uh quite tight
lipped about how it works but we're not
just restricted to making traditional hard drives larger or making smaller and
smaller transistors for our ssds there's
holographic data storage that takes the concept of a dual layer optical disc to
a completely new dimension instead of just storing data in a two-dimensional
pattern of what are effectively pits in the the surface holographic discs can
store data in threedimensional patterns
using nearly the entire thickness of the disc in fact multi-terabyte single diss
may be available at some point though
progress on actually getting holographic storage to Market has been agonizingly
slow and unfortunately the Jedi Council only existed very far away and very long
ago so they're not really around to show us how holocrons work but although none
of us actually have mitoch chlorians in our blood the farther flung future of
data storage might be inside our own
bodies I'm talking about DNA the
chemical that stores your entire genetic code down to that weird mole on your
butt so if you think back to high school biology you might remember that each
base pair of your DNA is either at or GC
meaning that DNA could be used as a
digital storage medium with each base pair corresponding to a one or a zero
biologists have been synthesizing DNA in the lab for quite a few years for tons
of different applications so perhaps it shouldn't be that surprising that
scientists are looking at it as a way to store data other than your genome a
single cubic millimeter of DNA can hold
over 685 terabytes of data so just think of
of how many games videos and dank memes
a DNA Drive could hold one day even if
it were only the size of a modern SD card DNA is also very stable and could
hold data for millions of years making it potentially a great choice for
archival storage down the line but hold on a minute lonus how do you retrieve
information from a puddle well although
scientists work with DNA in liquid form don't scoff at the concept of liquid
state storage researchers have recently used clusters of nanop particles only
about five microns wide about the same size as your typical bacterium suspended
in a fluid to hold huge amounts of data I'm talking one terabyte in only a
tablespoon this works by using small temperature changes to rearrange these
nanop particles to different states and since each cluster of these particles
can have millions of different states not just the binary zero and one we're
all used to liquid state storage could reach capacities that just aren't
possible with present-day Tech no word
though on when liquid drives might hit the market or if you'll have to buy them
in a bag like those weirdos from Eastern Canada already seem to do with milk are
you tired of hearing me try to sell you other people's stuff well you're in luck
