rces 2019 coverage is brought to you by dbrand their dbrand grip case and their
prism screen protector are a great way to keep your phone safe check them out
at the link in the video description so we're here in seagate and we don't
actually cover hard drives every time because let's face it
they're really really boring every year it's like okay we've got some
more capacity and like it might go a bit faster
also we've got green on our stickers now
but this is different so seagate's been working on a technology called heat
assisted magnetic recording or hammer since
1999 and the first time they built a
drive using this technology it lasted for a grand total of one sector worth of
rights and then it was destroyed so to call it
a concept at that stage is probably being
generous with that said they've been hard at work on it for the last 20 years
and they are finally at the point where they are ready to announce that hammer
drives will be shipping to customers this year so how does it work then
you can actually see a live feed of a hammerhead
totally intentional i'm sure so that's the drive head and it's hammer
technology writing data to the platter that is
running live next to me right here and every time it moves around you're going
to see a flash that's the head heating up the platter
to approximately 450 degrees celsius completely wiping
out any data that was already there and rewriting it this allows them to get
better aerial density to the point where we should see if they stay on target
terabyte drives by the year 2020. so
this drive right here combines their hammer technology with their sealed
helium drive technology which gives us the power consumption savings that you'd
expect from a modern drive as well now reliability remember that story at the
beginning how long are these things going to last so they have had tests
running in their lab for the last 18 months where they have individual heads
that have seen over 8 000 hours of just constant rights going
through them to put that in perspective that's a petabyte and a half of data
that's been written through a single head about equivalent to the entire netflix library that is if the internet
is to be believed so is it going to be reliable
well i mean i think that guy's job depends on
it so reliable
let's go with yeah for his sake but hammer doesn't solve
all of the hard drive industries problems something that uh
i've noticed and seagate has had other customers point out to them is that as
these drive capacities get higher and higher and higher without a performance
improvement to match we're getting to the point where it's kind of like what
happened with sd cards before they got past you know 20 to 30 megabytes a
second of write speeds where you'd like get a new sd card or a thumb drive and
you'd be like yeah so this is you know a terabyte or whatever but it would take
me literally weeks to fill it with data like it's
it's not really useful anymore so to address that
there's mach 2 and oh sorry this is actually running oh it's
like warm and what mach 2 is
is that's really cool so they've got a glass top on this drive so we can see
exactly what's happening but in effect in a multi-platter drive so most of the
top ones here are glass so you can see the two actuator arms moving
independently of each other so it uses a single sas interface which takes
advantage of sas's ability to have two sort of virtual ports available through
a single cable connected to a single connector so the drive's firmware and
processor take the incoming stream of data and split it between the two
separate heads this effectively doubles the iops performance of this
drive compared to a normal drive which would run off of a single actuator ARM
which brings us finally to the most controversial item here in the seagate
booth i've had everything from eye rolls to speaking directly to the person whose
pet project this is but this is the uh
you know what i forget the name so i'm gonna call it the hard drive zamboni and
what it effectively is is a like fiberglass shell with like these uh
tread style uh you know trailer mover
type you know treads on the front that contains a 4u
server rack so the idea is that amazon
has a product called uh what have they got they got snowball which is a little
one they've got snowmobile which i think like a semi-trailer where the idea is
they've got these high-speed interfaces where you pull these things up to your
data center offload everything and like literally drive it somewhere because
it's faster than trying to send it over the internet so this is supposed to be
like kind of like the middle stage where you like load a bunch of data onto it and
then you like drive it over somewhere and it could be like battery powered and then you could
offload it and that might be faster than using a network so
i'm gonna let you guys decide the controversy for me is this something the
world needs more of or something the world needs less of let me know in the
comments below speaking of things to let me know in the comments below let me know
how much you love these sponsor spots that we've been doing for dbrand all
show dbrand's grip is their new case that's super grippy it's got extra
clickable buttons and precision cutouts for your camera fingerprint sensor and
whatever else it is that you need it's also fully customizable with a dbrand
skin and their prism screen protector is well well basically the demo kind of
says everything you need to know about it it's got a great applicator so you can put it on perfectly every time and
the impact resistance of this thing is unreal like i was using a phone to
hammer a nail into a piece of wood peeling off the prism and the screen is
still pristine you gotta see it to believe it which is why we put footage
of it doing its thing in front of your face right now so your eyeballs can
capture that so check them out at the link in the video description
so thanks for watching guys don't miss any of our ces 2019 content by making
sure you're subscribed to Linus tech tips and we will see you at the next
absolutely nothing we're done now this one might get
released like earlier because the editors i don't know how they do the
things they do so there might actually be more coming
but i'm done peace and out i'm on a plane in like
four hours hell yeah
i mean i love ces sorry that's what i meant to say
