00:00:00.000 --> 00:00:07.359
for decades now the clear trend in storage technology has been to make

00:00:04.160 --> 00:00:10.000
drives as small as possible and as fast

00:00:07.359 --> 00:00:14.400
as possible and we've gone from having four megabyte drives that are twice as

00:00:12.240 --> 00:00:20.800
big as your average refrigerator in the 1950s to multi-terabyte ssds that are

00:00:18.480 --> 00:00:24.960
not much bigger than a credit card yet can still move

00:00:22.240 --> 00:00:30.640
gigabits of data per second but even as popular as those speedy two

00:00:27.840 --> 00:00:35.280
and a half inch ssds are it became clear that with advancements in flash storage

00:00:32.719 --> 00:00:41.040
technology we could shrink our digital repositories down even smaller without

00:00:38.320 --> 00:00:47.039
sacrificing speed say hello my friends to m.2 a new interface for both ssds and

00:00:44.879 --> 00:00:54.000
expansion cards that promises higher speeds and less bulk you see although

00:00:50.559 --> 00:00:56.480
SATA 3 ssds offer huge performance gains

00:00:54.000 --> 00:01:02.320
compared to traditional mechanical hard drives that SATA interface that cable on

00:00:59.840 --> 00:01:08.640
the back itself has a pretty serious bottleneck topping out at about 550 to

00:01:05.680 --> 00:01:13.520
600 megabytes per second and while that may seem very fast and indeed it is

00:01:10.799 --> 00:01:18.640
flash storage has advanced very rapidly in recent years and is now capable of

00:01:15.840 --> 00:01:22.880
handling data much more quickly than SATA will allow and although SATA

00:01:21.040 --> 00:01:28.320
express which you can learn more about here was designed to alleviate this

00:01:25.280 --> 00:01:30.880
bottleneck it is pretty difficult to

00:01:28.320 --> 00:01:34.960
find SATA express drives on the market even though motherboards supporting it

00:01:33.200 --> 00:01:40.560
are out there fortunately though m.2 provides the same

00:01:37.920 --> 00:01:46.079
speed benefits as SATA express with the extra advantage of being much much

00:01:42.799 --> 00:01:48.399
smaller and more versatile many m.2

00:01:46.079 --> 00:01:54.000
drives actually utilize your computer's pci express bus with the fastest m.2

00:01:51.920 --> 00:02:00.240
drives currently on the market using a pci express 3.0 x4 connection

00:01:57.600 --> 00:02:05.360
translating to a theoretical maximum of four gigabytes per second

00:02:03.520 --> 00:02:10.720
and although you probably won't see real world speeds quite that high especially

00:02:07.439 --> 00:02:12.800
not right now current m.2 PCIe drives

00:02:10.720 --> 00:02:16.480
will still be much faster than a regular SATA SSD and should continue to get

00:02:14.959 --> 00:02:22.000
faster in the future m.2 is also useful for things other than

00:02:19.040 --> 00:02:25.680
storage devices you can get wi-fi and bluetooth cards that will fit into your

00:02:23.599 --> 00:02:30.400
motherboard's m.2 slot and take advantage of pci express speeds without

00:02:27.760 --> 00:02:34.319
having a you know large card plugged in or a dongle hanging out of your case and

00:02:32.560 --> 00:02:38.080
even if you're just using m.2 for storage you still get the additional

00:02:36.239 --> 00:02:42.959
benefit of not having to mess around with any power or signal cables slot in

00:02:40.959 --> 00:02:46.959
the card put in a screw and you are good to go but

00:02:44.480 --> 00:02:53.120
before you rush out to buy a new m.2 SSD or wireless adapter or whatever remember

00:02:49.280 --> 00:02:54.080
this not all m.2 cards and slots are the

00:02:53.120 --> 00:02:58.480
same faster m.2 drives will utilize the

00:02:56.400 --> 00:03:04.319
newest version of pci express that is 3.0 as of right now as well as the new

00:03:02.000 --> 00:03:09.040
NVMe standard for interacting with the rest of the system so be sure to check

00:03:06.800 --> 00:03:16.720
for these things before you buy especially as some m.2 drives use PCIe

00:03:12.560 --> 00:03:19.280
2.0 the older ahci protocol or even the

00:03:16.720 --> 00:03:23.920
existing SATA bus so they're basically just an msata card that fits in an m.2

00:03:21.760 --> 00:03:28.720
slot so in the case of that last one you won't see any performance benefit at all

00:03:26.959 --> 00:03:34.319
and you also have to pay attention to the physical layout of the card unlike

00:03:31.599 --> 00:03:39.920
SATA m.2 even though it only has one name uses several different connector

00:03:36.799 --> 00:03:43.040
types so most m.2 slots on current

00:03:39.920 --> 00:03:47.200
motherboards use either connectors b or

00:03:43.040 --> 00:03:50.319
m for ssds and a or e for wireless

00:03:47.200 --> 00:03:52.640
adapters now some cards are actually

00:03:50.319 --> 00:03:56.640
compatible with multiple motherboard connectors so just make sure that

00:03:54.640 --> 00:03:59.599
whatever you're buying you are checking before you pull the trigger and then

00:03:58.400 --> 00:04:04.959
finally size matters with m.2 every m.2 card

00:04:03.040 --> 00:04:09.840
regardless of its connector type will have a number indicating its dimensions

00:04:06.879 --> 00:04:14.799
such as 2242 which means that it's 22 millimeters by 42 millimeters just so

00:04:12.560 --> 00:04:19.359
just like how some cases will only fit graphics cards up to a certain length

00:04:17.040 --> 00:04:24.639
some motherboards and notebooks aren't compatible with longer m.2 devices

00:04:23.840 --> 00:04:32.160
so i guess the final word is this although there may be more to remember with m.2

00:04:28.960 --> 00:04:33.840
the extra speed and flexibility is

00:04:32.160 --> 00:04:37.919
probably worth having to pay a little bit of attention that is to say unless

00:04:35.919 --> 00:04:43.840
the thought of leaving all 10 of those drive cages in your unnecessarily large

00:04:40.000 --> 00:04:46.160
gaming tower unused makes you feel sad

00:04:43.840 --> 00:04:50.080
speaking of making people sad you wouldn't want to make squarespace sad

00:04:48.160 --> 00:04:53.360
would you well if you had an ugly website

00:04:51.280 --> 00:04:58.320
they would be sad squarespace is the place to go to build a simple powerful

00:04:55.680 --> 00:05:02.960
beautiful functional website they've got 24 7 tech support so even if you're not

00:05:00.320 --> 00:05:07.840
a whiz kid programmer they can get you sorted out via live chat and email and

00:05:05.520 --> 00:05:11.919
this is great all of it is hosted on their server so it's all cloud managed
