1
00:00:00,160 --> 00:00:08,000
arguably one of the most impactful developments in storage has been the

2
00:00:05,000 --> 00:00:09,880
micro SD card with capacities of

3
00:00:08,000 --> 00:00:15,440
hundreds of gigabytes on a card about the size of your fingernail they've

4
00:00:12,160 --> 00:00:17,840
enabled awesome storage flexibility in

5
00:00:15,440 --> 00:00:23,160
tons of small devices that even full-scale home PCS 20 years ago

6
00:00:20,760 --> 00:00:29,519
couldn't dream of but in this age of SATA 3 and PCI Express drives it is

7
00:00:27,080 --> 00:00:36,559
clear that the bottleneck of most storage formats is still one that people

8
00:00:32,880 --> 00:00:39,520
want to overcome and that is speed and

9
00:00:36,559 --> 00:00:46,760
this is especially relevant to micro SD as these small memory cards are becoming

10
00:00:42,399 --> 00:00:50,120
increasingly popular as a more primary

11
00:00:46,760 --> 00:00:54,600
storage device uh such as in a netbook

12
00:00:50,120 --> 00:00:58,920
or a smartphone or Raspberry Pi well

13
00:00:54,600 --> 00:01:00,879
enter Universal flash storage or ufs a

14
00:00:58,920 --> 00:01:06,680
new format that aims to ultimately replace micro SD and although they're

15
00:01:03,800 --> 00:01:12,759
both about the same size physically and in terms of capacity right now ufs

16
00:01:09,280 --> 00:01:14,759
promises to be a heck of a lot quicker

17
00:01:12,759 --> 00:01:19,960
most mainstream micro SD cards have sequential read and write speeds below

18
00:01:17,439 --> 00:01:27,280
100 megabytes per second and even high-end UHS 2 cards have a theoretical

19
00:01:23,439 --> 00:01:30,280
cap of 312 megabytes per second one

20
00:01:27,280 --> 00:01:32,520
direction or 156 megab per second second

21
00:01:30,280 --> 00:01:38,520
in full duplex with most cards being slower than that ufs on the other hand

22
00:01:35,640 --> 00:01:45,119
can perform sequential reads at up to 530 megabytes per second which

23
00:01:41,399 --> 00:01:47,840
essentially matches high-end sata3 ssds

24
00:01:45,119 --> 00:01:53,119
right speeds will be as high as 170 megabytes per second allowing for better

25
00:01:50,240 --> 00:01:58,119
performance when recording 4K video or taking large uncompressed photos things

26
00:01:55,880 --> 00:02:02,560
that are becoming more and more common as feature-rich smartphones increase in

27
00:02:00,399 --> 00:02:06,840
price and become more widespread and if you're interested in

28
00:02:04,640 --> 00:02:11,840
using a ufs card for things other than just storing large files such as running

29
00:02:09,080 --> 00:02:17,040
mobile apps or using it instead of a hard drive in something like a

30
00:02:13,080 --> 00:02:19,319
Chromebook ufs also has vastly improve

31
00:02:17,040 --> 00:02:25,280
random performance uh which is usually expressed in iops or inputs and outputs

32
00:02:22,160 --> 00:02:27,560
per second which is the most important

33
00:02:25,280 --> 00:02:32,319
thing in some ways for everyday allpurpose use something you can learn

34
00:02:29,519 --> 00:02:37,959
more about out in this video so the fastest current gen micro SD cards can

35
00:02:34,519 --> 00:02:41,959
get a little over 3,000 iops in 4k

36
00:02:37,959 --> 00:02:46,319
random reads but ufs cards can do up to

37
00:02:41,959 --> 00:02:48,400
40,000 read and 30,000 right ey Ops

38
00:02:46,319 --> 00:02:54,000
that's not quite as fast as a current mid-range SSD which might get around

39
00:02:50,680 --> 00:02:57,480
70,000 iops but that is still insanely

40
00:02:54,000 --> 00:02:59,440
fast for such a small card and several

41
00:02:57,480 --> 00:03:03,920
thousand times faster than your typical mechan mechanical hard drive so not only

42
00:03:02,280 --> 00:03:08,840
do these increased speeds mean better performance they might also give us

43
00:03:06,200 --> 00:03:12,720
greater flexibility with regards to app storage options as many developers

44
00:03:11,400 --> 00:03:17,720
haven't allowed their apps to run directly off of micro SD cards due to

45
00:03:15,280 --> 00:03:21,959
concerns about responsiveness and since devs might be more open to having their

46
00:03:19,480 --> 00:03:26,000
software run off of usfs cards you're not going to be as hamstrung by your

47
00:03:23,440 --> 00:03:30,480
phones internal memory and you might even get well more value optimized

48
00:03:28,640 --> 00:03:35,519
choices for your next phone since manufacturers won't have to maintain SKS

49
00:03:33,519 --> 00:03:41,159
with a bunch of different capacities inside you can just put in your own

50
00:03:38,120 --> 00:03:43,400
storage add in the significantly lower

51
00:03:41,159 --> 00:03:46,720
power consumption compared to micro SD which will keep your battery powered up

52
00:03:44,879 --> 00:03:51,599
for longer especially if you're taking pictures or recording videos and ufs

53
00:03:49,480 --> 00:03:55,879
looks set to make our mobile gadgets even more useful than ever before though

54
00:03:54,519 --> 00:04:00,760
you might have to wait a bit to take advantage of it Samsung just announced

55
00:03:58,280 --> 00:04:04,319
ufs quite recently in the cards haven't quite hit the market yet not to mention

56
00:04:02,319 --> 00:04:07,680
that there aren't any readers for them however this might be good news for

57
00:04:06,040 --> 00:04:11,720
those looking to buy a Galaxy phone in the near future especially as Samsung

58
00:04:09,959 --> 00:04:17,239
has developed a slot that can accept both micro SD and ufs cards even though

59
00:04:14,920 --> 00:04:21,880
the two formats aren't electrically compatible but regardless of your device

60
00:04:19,560 --> 00:04:26,120
of choice keep an eye out for ufs cards soon because nothing could be worse then

61
00:04:24,280 --> 00:04:30,360
your micro SD card depleting your battery while you're in the middle of

62
00:04:27,520 --> 00:04:34,520
playing Pokemon go could anything be worse than that no it

63
00:04:32,960 --> 00:04:40,080
could not speaking of things that couldn't be worse does your job suck are
