hey Gordon I just got a new toy and I need to get a memory card for it what's
the best way to find out how to get a memory card okay first you have to have
a seat I'm gonna explain to you okay I got it what you need to know there's
only four things pay attention the first one I'm gonna give it to is the most
confusing part oh great a lot of people think all memory cards are the same buy
the cheapest one for the lowest price I'm done yeah well it very much depends
on what you're using it for the device you're using it for okay well let's
start off with video oh you know this awesome DJI Osmo pocket or you know what
kind of things do I need to be looking for with that so for video there are
three ways they explain it all of them are confusing the one you're most
familiar with is a class 2 class 4 class 6 class 10 rice got the little C with
the governor will see on there it's got a little C with a 10 that means writes
10 megabytes a second uninterrupted for video ok doesn't stop because if you
stop you break that video stream it just stops right definitely so that coexists
C 2 through 10 with u1 and u3 okay and also V 2 V 4 V 6 V 10 V 30 and now V 90
as well ok so which one am i focusing on so all of those pertain to video and
what's crazy is they all all the memory cards because you're afraid you may not
buy it if it doesn't have that little thing on there they may have all of them
on their first read the manual if your whatever your manual tells you to buy
just get that that's the easiest way not to get messed up okay the easiest way
okay but if you don't know that you basically class 10 works for 1080p video
30 frames a second general class 10 for 4k 30 and lower is good if you're going
higher than that then you're gonna want a V 30 v60 you have a 8k drone or a
drone that's doing surround video and also or recording multiple video streams
and also GPS data you're gonna want the highest performance card v90 probably
whatever they recommend generally 8k and up is B 60 B 90 range
and then if you're doing multiple streams or GPS day and a v90 so why not
just get the highest speed you know and say hey the I know I'm gonna be in good
hands right well first one is you're overpaying cuz v90 cars are not cheap
because it is meant for a drone a cait drone with all these kind of cool things
you're using it in this GoPro three from five or six years ago it's like total
waste of money it may not even formatted it correctly because it's too large I
generally recommend for very old hard work both class 10 class sentence a safe
place to go one thing I think people in Genoa cuz it confused me it confused a
lot of people's again you look at the packaging it'll say class 10 and V 30
and you go like why does it say V 30 in class 10 if V 30 is 30 makes a second in
class 10 is 10 makes a second isn't that good enough and this is where it gets
confusing they just want to have class set on there because they don't want to
not sell you this memory card huh so V 30 means pretty much it's gonna be good
for 30 makes a second writes okay and as for video that's for video that's pretty
you know so okay what about photos photography so for photography it's
different you generally want to buy a memory card where they brag about it if
they brag about their write speed this memory card says 90 megabytes a second
does Lexar professional card it says 1000 X yeah so they're basically saying
we can hit a minimum write speed and in an SLR a DSLR that makes a difference so
V 30 doesn't necessarily mean it's gonna write the fastest and it's funny you can
get memory cards that will write it at you know 90 megabytes a second and
though they won't be v 30 rated or vv9 be rated hmm okay so because it's really
only for still camera where when you take pictures it fills up that buffer it
pauses it's not a problem video cameras you can never stop so it's not a problem
generally go for explicit write speed on on the on the packaging it's a way to go
for high-performance SLRs one caveat a lot of these things are gonna really
disappoint you this sony camera it's somewhat older this thing uses
usb2 it doesn't write faster than 35 megabytes a second so if you buy a card
that writes at 90 megabytes a second you're basically throwing away all that
performance you paid for so you need to read the manual they will tell you that
demand what because they you will have you may have to see some reviews out
there I think generally the rule is if it's older you know you don't want to
pay for the newest thing it's just not good so if it's a brand new 2019 camera
by all means newest memory card probably you get you the best performance ever
it's three or four years old you could probably step back two three
steps and it won't make any difference USB to 35 megabytes a second okay they
just put a ton of memory in here to buffer it out so it didn't matter great
okay well what about phones I just got this new phone
and I want to expand the the capabilities I got the cheapest option
so the the less internal storage so I can just expand it later right so
there's a new specification for Android for writing it's it psyops it's not
about writing video constantly or writing a lot of data at the same time
it's about randomly jumping around that memory card reading and writing so a1
means greater I ops I can write and read more random read and writes a to even
more sounds great right all right sounds great some of the testing that I've done
in Android phones I use an LG v40 it didn't really make that much of a
difference in random reads random writes even though this is an a2 card it should
have blown away the little crappy micro SD cards I had yeah and looking into it
is because the Qualcomm 845 Snapdragon which is still used in some top of the
line phones doesn't even support a - right so if you have you got you buy a
brand new a2 memory card you've paid all this money for it you may not need to
see a very significant increase in random read random write performance so
what's even worse is they don't even support a 1 yet most of them are
supporting standards from 60 years ago so even if you bought an a1 card you're
not gonna see the full potential and you do apparently have to have it supported
in the controller and the firmware to support a2 and a1 it may not make that
much of a difference it can be somewhat faster because the cards generally are
gonna be better performance at random reads random writes okay
but it's surprising to see brand-new phones not support a1 a2 weight so
should I pay the hundred dollars to upgrade the internal memory or pay the
hundred dollars to get a card do the internal memory that's faster I know
that's gonna really hurt paying your your carrier that money but if yours a
64 gig or 128 gig or 512 gig that's gonna get you the most performance
because I know everybody goes I'll do a 32 gig phone and buy a 512 gig memory
card is cheap yeah performance is gonna suck I'm gonna be disappointed
dang it if you're storing videos to watch just you're burning your videos
your pictures generally ok but as far as storing your applications on there it's
gonna really disappoint you so pony up to put the memory in the phone ok well
so in my car I've got a new dashcam that I just installed and I need to get a
card for it what what number am I looking at this time yeah so that is the
worst thing so if you're doing a memory card for your dash camera or
surveillance camera at home okay or C 10 V 30 your a1 or a2 your explicit rights
though may not matter as much shirt certainly you're gonna want to hit your
class 10 because if you're doing 4k surveillance camera but the other thing
you're probably going to want to pay attention to on memory cards is this
thing it's called the high endurance it's not really a rating but they have
these they're called heavy duty or high endurance cards and
what it is is the kind of memory that they use in the card or firmware that is
tweaked for longer life remember these memory cards you put them in your phone
you put them in your recorder you're not gonna really use them that much you
might record a cup an hour two hours five hours a week that's a heavy user
yeah you put that in a surveillance camera it's running 24/7 12 months a
year I've done that I've had them they just stopped working after six months
eight months basically the memory cards you know they're they're TLC they're
high capacity they're really cheap cards they basically give up the ghost after a
year less than a year and they don't tell you okay I have had some that work
fine but it's kind of a draw you don't really know
what these again are gonna do a lot of the hind yurts member cards will
actually tell you how many hours they will last
Oh a larger the card the more hours and also they say five thousand hours ten
thousand hours interesting these don't mention it they don't mention it
anywhere on the packaging because that's not really something you're worried
about with these you're not gonna do ten thousand hours in a GoPro or one of you
just it's just not gonna happen there's surveillance camera dashcam very very
important spec to pay attention to alright my last question is why is this
so damn complicated Gordon well it's so important it's so complicated because
you would think they would just put the 30 on here B 30 would mean it works with
you three it works with class ten but what the car makers are afraid of is you
go to the store and you want to see class ten my manual says Gordon says I
went class 10 so they put everything on there they haven't really figured out a
good way to communicate it's all backwards compatible right because it
should be all pack words compatible that's the great thing about memory
cards they're generally kept backwards compatible not always the case but
generally they are backwards compatible but they can't do that they want to they
don't want to risk losing a sale because if they don't have you know they're
people aren't gonna buy it so that you look at these memory cards you see a u3
you see a class 10 which doesn't make any sense because you three card writes
at 30 megabytes a second class 10 writes of 10 megabytes a second for video as
well well I do that for you if you don't have it you may not buy it so it's sort
of done in order to help you understand it but it also confuses you too because
there's so many things on here you don't know what it means
all right I'm gonna have to go back and watch this video a couple times to
hopefully try to understand it yes and hopefully you will understand it as well
I want to hear if you've had it have any horror stories in the comments below of
buying a card and realizing that it didn't work great I'm sure it happens to
all of us oh yes yes it's very confusing but hopefully that helps you a little
bit yeah and thank you for doing all the testing I really appreciate it if you
want more information on it you've got a great article over yes see worldcom we
will link down in the description below all right well thank you for doing all
this testing Gordon I really appreciate it and we will
see you later
