1
00:00:00,080 --> 00:00:08,240
what's in the works for the future of computer data storage I mean we've gone

2
00:00:04,560 --> 00:00:10,880
from 2 gabt to 2 terabytes being a

3
00:00:08,240 --> 00:00:17,439
typical amount of PC storage in less than 20 years a thousandfold increase so

4
00:00:15,440 --> 00:00:22,519
are things just going to keep becoming exponentially more capacitors why don't

5
00:00:20,160 --> 00:00:28,240
we start answering this question with a look at our old friend the mechanical

6
00:00:25,160 --> 00:00:30,240
hard drive already there are a number of

7
00:00:28,240 --> 00:00:34,879
Technologies in the works that will make hard drives more spacious while still

8
00:00:32,759 --> 00:00:40,160
allowing them to fit in that familiar 3 and 1/2 in enclosure hard drive makers

9
00:00:37,840 --> 00:00:45,559
like Seagate and Western Digital are working on Technologies such as shingled

10
00:00:42,600 --> 00:00:51,559
magnetic recording which overlaps data tracks to essentially make them narrower

11
00:00:48,879 --> 00:00:57,800
bit patterned media which can encode one bit of data to just one magnetic grain

12
00:00:54,840 --> 00:01:02,960
instead of a group and heat assisted magnetic recording or hammer

13
00:01:00,719 --> 00:01:07,400
which heats up small areas of the hard disk allowing the magnetic grains

14
00:01:05,280 --> 00:01:12,000
themselves that store the data to be a lot smaller and you can learn more about

15
00:01:09,119 --> 00:01:18,080
hammer in this video here these Technologies are expected to help push

16
00:01:14,439 --> 00:01:19,159
hard drive capacities to 50 terabytes by

17
00:01:18,080 --> 00:01:25,119
the year 2020 wow but aside from changing how

18
00:01:22,840 --> 00:01:30,200
magnetic platter data recording Works manufacturers are also looking at using

19
00:01:27,280 --> 00:01:35,960
more exotic materials hard drives filled with helium instead of good oldfashioned

20
00:01:32,920 --> 00:01:38,320
air are already on the market since

21
00:01:35,960 --> 00:01:43,240
helium is less dense than air there's less fluid resistance when the drive

22
00:01:40,640 --> 00:01:48,040
platters spin meaning more precise positioning of the Reed right head with

23
00:01:45,520 --> 00:01:53,719
lower power consumption and all of this without making your mp3 sound like the

24
00:01:50,320 --> 00:01:56,039
singer just sucked air from a balloon of

25
00:01:53,719 --> 00:02:01,039
course by this point you may have moved off of hard drives in favor of ssds in

26
00:01:58,920 --> 00:02:06,759
which case you might be more interested in Intel and micron's 3D Cross Point

27
00:02:04,399 --> 00:02:12,160
which features very dense Arrangements of memory cells that don't require

28
00:02:09,200 --> 00:02:18,000
transistors leading to higher capacities 3D Cross Point will also have latencies

29
00:02:14,879 --> 00:02:20,640
up to a, times lower than traditional

30
00:02:18,000 --> 00:02:26,080
nand and will last for much longer than a conventional SSD meaning we could see

31
00:02:23,120 --> 00:02:31,040
drives much bigger and faster than what we have today and Samsung is also

32
00:02:28,680 --> 00:02:38,040
working on a competing technology called zand though they're being uh quite tight

33
00:02:34,840 --> 00:02:40,000
lipped about how it works but we're not

34
00:02:38,040 --> 00:02:46,040
just restricted to making traditional hard drives larger or making smaller and

35
00:02:42,800 --> 00:02:48,920
smaller transistors for our ssds there's

36
00:02:46,040 --> 00:02:54,800
holographic data storage that takes the concept of a dual layer optical disc to

37
00:02:52,000 --> 00:02:59,680
a completely new dimension instead of just storing data in a two-dimensional

38
00:02:57,239 --> 00:03:05,799
pattern of what are effectively pits in the the surface holographic discs can

39
00:03:02,720 --> 00:03:08,680
store data in threedimensional patterns

40
00:03:05,799 --> 00:03:16,400
using nearly the entire thickness of the disc in fact multi-terabyte single diss

41
00:03:13,000 --> 00:03:18,760
may be available at some point though

42
00:03:16,400 --> 00:03:24,360
progress on actually getting holographic storage to Market has been agonizingly

43
00:03:21,720 --> 00:03:27,920
slow and unfortunately the Jedi Council only existed very far away and very long

44
00:03:26,440 --> 00:03:32,920
ago so they're not really around to show us how holocrons work but although none

45
00:03:30,840 --> 00:03:39,120
of us actually have mitoch chlorians in our blood the farther flung future of

46
00:03:35,560 --> 00:03:42,519
data storage might be inside our own

47
00:03:39,120 --> 00:03:45,080
bodies I'm talking about DNA the

48
00:03:42,519 --> 00:03:49,599
chemical that stores your entire genetic code down to that weird mole on your

49
00:03:47,080 --> 00:03:57,439
butt so if you think back to high school biology you might remember that each

50
00:03:52,280 --> 00:04:00,840
base pair of your DNA is either at or GC

51
00:03:57,439 --> 00:04:03,319
meaning that DNA could be used as a

52
00:04:00,840 --> 00:04:09,159
digital storage medium with each base pair corresponding to a one or a zero

53
00:04:06,959 --> 00:04:14,120
biologists have been synthesizing DNA in the lab for quite a few years for tons

54
00:04:11,720 --> 00:04:17,840
of different applications so perhaps it shouldn't be that surprising that

55
00:04:15,879 --> 00:04:24,400
scientists are looking at it as a way to store data other than your genome a

56
00:04:20,880 --> 00:04:25,360
single cubic millimeter of DNA can hold

57
00:04:24,400 --> 00:04:33,720
over 685 terabytes of data so just think of

58
00:04:29,720 --> 00:04:36,759
of how many games videos and dank memes

59
00:04:33,720 --> 00:04:39,160
a DNA Drive could hold one day even if

60
00:04:36,759 --> 00:04:45,240
it were only the size of a modern SD card DNA is also very stable and could

61
00:04:42,800 --> 00:04:50,680
hold data for millions of years making it potentially a great choice for

62
00:04:47,720 --> 00:04:56,840
archival storage down the line but hold on a minute lonus how do you retrieve

63
00:04:53,600 --> 00:04:59,720
information from a puddle well although

64
00:04:56,840 --> 00:05:04,880
scientists work with DNA in liquid form don't scoff at the concept of liquid

65
00:05:02,000 --> 00:05:10,479
state storage researchers have recently used clusters of nanop particles only

66
00:05:07,759 --> 00:05:16,160
about five microns wide about the same size as your typical bacterium suspended

67
00:05:13,280 --> 00:05:21,960
in a fluid to hold huge amounts of data I'm talking one terabyte in only a

68
00:05:19,000 --> 00:05:27,440
tablespoon this works by using small temperature changes to rearrange these

69
00:05:24,600 --> 00:05:31,560
nanop particles to different states and since each cluster of these particles

70
00:05:29,360 --> 00:05:36,440
can have millions of different states not just the binary zero and one we're

71
00:05:33,960 --> 00:05:41,960
all used to liquid state storage could reach capacities that just aren't

72
00:05:38,759 --> 00:05:43,919
possible with present-day Tech no word

73
00:05:41,960 --> 00:05:47,319
though on when liquid drives might hit the market or if you'll have to buy them

74
00:05:45,360 --> 00:05:52,240
in a bag like those weirdos from Eastern Canada already seem to do with milk are

75
00:05:50,039 --> 00:05:57,800
you tired of hearing me try to sell you other people's stuff well you're in luck
