00:00:00.160 --> 00:00:08.000
arguably one of the most impactful developments in storage has been the

00:00:05.000 --> 00:00:09.880
micro SD card with capacities of

00:00:08.000 --> 00:00:15.440
hundreds of gigabytes on a card about the size of your fingernail they've

00:00:12.160 --> 00:00:17.840
enabled awesome storage flexibility in

00:00:15.440 --> 00:00:23.160
tons of small devices that even full-scale home PCS 20 years ago

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

00:00:27.080 --> 00:00:36.559
clear that the bottleneck of most storage formats is still one that people

00:00:32.880 --> 00:00:39.520
want to overcome and that is speed and

00:00:36.559 --> 00:00:46.760
this is especially relevant to micro SD as these small memory cards are becoming

00:00:42.399 --> 00:00:50.120
increasingly popular as a more primary

00:00:46.760 --> 00:00:54.600
storage device uh such as in a netbook

00:00:50.120 --> 00:00:58.920
or a smartphone or Raspberry Pi well

00:00:54.600 --> 00:01:00.879
enter Universal flash storage or ufs a

00:00:58.920 --> 00:01:06.680
new format that aims to ultimately replace micro SD and although they're

00:01:03.800 --> 00:01:12.759
both about the same size physically and in terms of capacity right now ufs

00:01:09.280 --> 00:01:14.759
promises to be a heck of a lot quicker

00:01:12.759 --> 00:01:19.960
most mainstream micro SD cards have sequential read and write speeds below

00:01:17.439 --> 00:01:27.280
100 megabytes per second and even high-end UHS 2 cards have a theoretical

00:01:23.439 --> 00:01:30.280
cap of 312 megabytes per second one

00:01:27.280 --> 00:01:32.520
direction or 156 megab per second second

00:01:30.280 --> 00:01:38.520
in full duplex with most cards being slower than that ufs on the other hand

00:01:35.640 --> 00:01:45.119
can perform sequential reads at up to 530 megabytes per second which

00:01:41.399 --> 00:01:47.840
essentially matches high-end sata3 ssds

00:01:45.119 --> 00:01:53.119
right speeds will be as high as 170 megabytes per second allowing for better

00:01:50.240 --> 00:01:58.119
performance when recording 4K video or taking large uncompressed photos things

00:01:55.880 --> 00:02:02.560
that are becoming more and more common as feature-rich smartphones increase in

00:02:00.399 --> 00:02:06.840
price and become more widespread and if you're interested in

00:02:04.640 --> 00:02:11.840
using a ufs card for things other than just storing large files such as running

00:02:09.080 --> 00:02:17.040
mobile apps or using it instead of a hard drive in something like a

00:02:13.080 --> 00:02:19.319
Chromebook ufs also has vastly improve

00:02:17.040 --> 00:02:25.280
random performance uh which is usually expressed in iops or inputs and outputs

00:02:22.160 --> 00:02:27.560
per second which is the most important

00:02:25.280 --> 00:02:32.319
thing in some ways for everyday allpurpose use something you can learn

00:02:29.519 --> 00:02:37.959
more about out in this video so the fastest current gen micro SD cards can

00:02:34.519 --> 00:02:41.959
get a little over 3,000 iops in 4k

00:02:37.959 --> 00:02:46.319
random reads but ufs cards can do up to

00:02:41.959 --> 00:02:48.400
40,000 read and 30,000 right ey Ops

00:02:46.319 --> 00:02:54.000
that's not quite as fast as a current mid-range SSD which might get around

00:02:50.680 --> 00:02:57.480
70,000 iops but that is still insanely

00:02:54.000 --> 00:02:59.440
fast for such a small card and several

00:02:57.480 --> 00:03:03.920
thousand times faster than your typical mechan mechanical hard drive so not only

00:03:02.280 --> 00:03:08.840
do these increased speeds mean better performance they might also give us

00:03:06.200 --> 00:03:12.720
greater flexibility with regards to app storage options as many developers

00:03:11.400 --> 00:03:17.720
haven't allowed their apps to run directly off of micro SD cards due to

00:03:15.280 --> 00:03:21.959
concerns about responsiveness and since devs might be more open to having their

00:03:19.480 --> 00:03:26.000
software run off of usfs cards you're not going to be as hamstrung by your

00:03:23.440 --> 00:03:30.480
phones internal memory and you might even get well more value optimized

00:03:28.640 --> 00:03:35.519
choices for your next phone since manufacturers won't have to maintain SKS

00:03:33.519 --> 00:03:41.159
with a bunch of different capacities inside you can just put in your own

00:03:38.120 --> 00:03:43.400
storage add in the significantly lower

00:03:41.159 --> 00:03:46.720
power consumption compared to micro SD which will keep your battery powered up

00:03:44.879 --> 00:03:51.599
for longer especially if you're taking pictures or recording videos and ufs

00:03:49.480 --> 00:03:55.879
looks set to make our mobile gadgets even more useful than ever before though

00:03:54.519 --> 00:04:00.760
you might have to wait a bit to take advantage of it Samsung just announced

00:03:58.280 --> 00:04:04.319
ufs quite recently in the cards haven't quite hit the market yet not to mention

00:04:02.319 --> 00:04:07.680
that there aren't any readers for them however this might be good news for

00:04:06.040 --> 00:04:11.720
those looking to buy a Galaxy phone in the near future especially as Samsung

00:04:09.959 --> 00:04:17.239
has developed a slot that can accept both micro SD and ufs cards even though

00:04:14.920 --> 00:04:21.880
the two formats aren't electrically compatible but regardless of your device

00:04:19.560 --> 00:04:26.120
of choice keep an eye out for ufs cards soon because nothing could be worse then

00:04:24.280 --> 00:04:30.360
your micro SD card depleting your battery while you're in the middle of

00:04:27.520 --> 00:04:34.520
playing Pokemon go could anything be worse than that no it

00:04:32.960 --> 00:04:40.080
could not speaking of things that couldn't be worse does your job suck are
