00:00:00.080 --> 00:00:06.480
rces 2019 coverage is brought to you by dbrand their dbrand grip case and their

00:00:04.560 --> 00:00:10.080
prism screen protector are a great way to keep your phone safe check them out

00:00:07.839 --> 00:00:14.240
at the link in the video description so we're here in seagate and we don't

00:00:11.599 --> 00:00:19.039
actually cover hard drives every time because let's face it

00:00:17.039 --> 00:00:23.039
they're really really boring every year it's like okay we've got some

00:00:20.880 --> 00:00:28.640
more capacity and like it might go a bit faster

00:00:24.080 --> 00:00:31.119
also we've got green on our stickers now

00:00:28.640 --> 00:00:35.280
but this is different so seagate's been working on a technology called heat

00:00:32.880 --> 00:00:40.079
assisted magnetic recording or hammer since

00:00:36.840 --> 00:00:42.399
1999 and the first time they built a

00:00:40.079 --> 00:00:46.399
drive using this technology it lasted for a grand total of one sector worth of

00:00:45.440 --> 00:00:49.520
rights and then it was destroyed so to call it

00:00:48.480 --> 00:00:53.440
a concept at that stage is probably being

00:00:51.600 --> 00:00:58.480
generous with that said they've been hard at work on it for the last 20 years

00:00:56.559 --> 00:01:03.039
and they are finally at the point where they are ready to announce that hammer

00:01:00.879 --> 00:01:08.080
drives will be shipping to customers this year so how does it work then

00:01:05.920 --> 00:01:11.520
you can actually see a live feed of a hammerhead

00:01:09.439 --> 00:01:14.320
totally intentional i'm sure so that's the drive head and it's hammer

00:01:13.200 --> 00:01:18.960
technology writing data to the platter that is

00:01:16.640 --> 00:01:22.240
running live next to me right here and every time it moves around you're going

00:01:20.400 --> 00:01:26.360
to see a flash that's the head heating up the platter

00:01:24.560 --> 00:01:32.000
to approximately 450 degrees celsius completely wiping

00:01:29.920 --> 00:01:36.079
out any data that was already there and rewriting it this allows them to get

00:01:34.159 --> 00:01:43.040
better aerial density to the point where we should see if they stay on target

00:01:39.520 --> 00:01:44.720
terabyte drives by the year 2020. so

00:01:43.040 --> 00:01:48.240
this drive right here combines their hammer technology with their sealed

00:01:46.479 --> 00:01:52.720
helium drive technology which gives us the power consumption savings that you'd

00:01:49.759 --> 00:01:56.479
expect from a modern drive as well now reliability remember that story at the

00:01:54.880 --> 00:02:01.439
beginning how long are these things going to last so they have had tests

00:01:58.719 --> 00:02:06.479
running in their lab for the last 18 months where they have individual heads

00:02:03.840 --> 00:02:11.920
that have seen over 8 000 hours of just constant rights going

00:02:10.080 --> 00:02:15.040
through them to put that in perspective that's a petabyte and a half of data

00:02:13.920 --> 00:02:20.800
that's been written through a single head about equivalent to the entire netflix library that is if the internet

00:02:19.040 --> 00:02:24.400
is to be believed so is it going to be reliable

00:02:23.360 --> 00:02:28.800
well i mean i think that guy's job depends on

00:02:26.400 --> 00:02:33.120
it so reliable

00:02:30.640 --> 00:02:36.560
let's go with yeah for his sake but hammer doesn't solve

00:02:35.280 --> 00:02:40.400
all of the hard drive industries problems something that uh

00:02:38.560 --> 00:02:44.160
i've noticed and seagate has had other customers point out to them is that as

00:02:42.319 --> 00:02:48.640
these drive capacities get higher and higher and higher without a performance

00:02:46.720 --> 00:02:52.879
improvement to match we're getting to the point where it's kind of like what

00:02:50.239 --> 00:02:56.800
happened with sd cards before they got past you know 20 to 30 megabytes a

00:02:55.040 --> 00:03:01.200
second of write speeds where you'd like get a new sd card or a thumb drive and

00:02:58.720 --> 00:03:05.360
you'd be like yeah so this is you know a terabyte or whatever but it would take

00:03:02.720 --> 00:03:09.200
me literally weeks to fill it with data like it's

00:03:06.560 --> 00:03:12.959
it's not really useful anymore so to address that

00:03:11.040 --> 00:03:16.159
there's mach 2 and oh sorry this is actually running oh it's

00:03:14.560 --> 00:03:20.400
like warm and what mach 2 is

00:03:18.400 --> 00:03:24.480
is that's really cool so they've got a glass top on this drive so we can see

00:03:22.000 --> 00:03:28.879
exactly what's happening but in effect in a multi-platter drive so most of the

00:03:26.879 --> 00:03:34.239
top ones here are glass so you can see the two actuator arms moving

00:03:31.440 --> 00:03:38.879
independently of each other so it uses a single sas interface which takes

00:03:36.159 --> 00:03:43.519
advantage of sas's ability to have two sort of virtual ports available through

00:03:41.360 --> 00:03:47.680
a single cable connected to a single connector so the drive's firmware and

00:03:45.760 --> 00:03:53.680
processor take the incoming stream of data and split it between the two

00:03:50.959 --> 00:03:59.120
separate heads this effectively doubles the iops performance of this

00:03:56.480 --> 00:04:04.400
drive compared to a normal drive which would run off of a single actuator ARM

00:04:02.720 --> 00:04:08.480
which brings us finally to the most controversial item here in the seagate

00:04:06.159 --> 00:04:13.920
booth i've had everything from eye rolls to speaking directly to the person whose

00:04:10.560 --> 00:04:15.200
pet project this is but this is the uh

00:04:13.920 --> 00:04:20.000
you know what i forget the name so i'm gonna call it the hard drive zamboni and

00:04:17.600 --> 00:04:26.800
what it effectively is is a like fiberglass shell with like these uh

00:04:23.120 --> 00:04:29.520
tread style uh you know trailer mover

00:04:26.800 --> 00:04:35.199
type you know treads on the front that contains a 4u

00:04:32.000 --> 00:04:37.440
server rack so the idea is that amazon

00:04:35.199 --> 00:04:40.560
has a product called uh what have they got they got snowball which is a little

00:04:38.880 --> 00:04:44.560
one they've got snowmobile which i think like a semi-trailer where the idea is

00:04:42.639 --> 00:04:47.919
they've got these high-speed interfaces where you pull these things up to your

00:04:45.840 --> 00:04:50.639
data center offload everything and like literally drive it somewhere because

00:04:49.199 --> 00:04:54.320
it's faster than trying to send it over the internet so this is supposed to be

00:04:53.440 --> 00:04:59.360
like kind of like the middle stage where you like load a bunch of data onto it and

00:04:58.160 --> 00:05:04.400
then you like drive it over somewhere and it could be like battery powered and then you could

00:05:02.479 --> 00:05:07.759
offload it and that might be faster than using a network so

00:05:06.400 --> 00:05:11.919
i'm gonna let you guys decide the controversy for me is this something the

00:05:10.160 --> 00:05:15.600
world needs more of or something the world needs less of let me know in the

00:05:14.000 --> 00:05:20.800
comments below speaking of things to let me know in the comments below let me know

00:05:19.120 --> 00:05:24.720
how much you love these sponsor spots that we've been doing for dbrand all

00:05:22.160 --> 00:05:28.160
show dbrand's grip is their new case that's super grippy it's got extra

00:05:26.160 --> 00:05:31.520
clickable buttons and precision cutouts for your camera fingerprint sensor and

00:05:30.000 --> 00:05:36.240
whatever else it is that you need it's also fully customizable with a dbrand

00:05:33.360 --> 00:05:39.199
skin and their prism screen protector is well well basically the demo kind of

00:05:37.919 --> 00:05:44.639
says everything you need to know about it it's got a great applicator so you can put it on perfectly every time and

00:05:42.479 --> 00:05:48.400
the impact resistance of this thing is unreal like i was using a phone to

00:05:46.639 --> 00:05:51.680
hammer a nail into a piece of wood peeling off the prism and the screen is

00:05:50.080 --> 00:05:55.199
still pristine you gotta see it to believe it which is why we put footage

00:05:53.280 --> 00:05:58.880
of it doing its thing in front of your face right now so your eyeballs can

00:05:57.360 --> 00:06:04.160
capture that so check them out at the link in the video description

00:06:02.720 --> 00:06:08.400
so thanks for watching guys don't miss any of our ces 2019 content by making

00:06:07.120 --> 00:06:12.720
sure you're subscribed to Linus tech tips and we will see you at the next

00:06:10.880 --> 00:06:17.120
absolutely nothing we're done now this one might get

00:06:14.479 --> 00:06:19.919
released like earlier because the editors i don't know how they do the

00:06:18.560 --> 00:06:23.039
things they do so there might actually be more coming

00:06:21.840 --> 00:06:26.319
but i'm done peace and out i'm on a plane in like

00:06:24.880 --> 00:06:29.919
four hours hell yeah

00:06:28.319 --> 00:06:32.560
i mean i love ces sorry that's what i meant to say
