Whats up youtube? so i'm here on Mac OS Sierra and i want to show you guys
something pretty exciting
at least for me it was I found in the disk utilities here and i know some
other websites are reporting it now to a raid assistant so rate has finally
returned to mac OS where lacked last year and alka pattan now the reason this
is important is rate is really great for combining multiple drives so as you see
here I have two USB 16 gigabyte flash drives and with a raid I could combine
the Mike Deaver make it so they duplicate themselves so i have 1 15
gigabytes drive and it's always duplicated on to another or I could
stripe them and make about a 32 gigabyte drive and have the speed be increased so
i'm going to show you guys how to do that in mac OS c are here so what you do
is you open up your disk utilities and head to raid the rate assistant now
the rate i was talking about is called striped mirrored would be where it makes
a duplicate one disk and then you have two copies so and then this one here
these are for other raid sequences that when you get into a larger array of
disks it's becomes a little more complicated you have to have ax amount
of disk so with this tutorial I'm just going to stick with the two main raid
partitions that you would probably use
so it's going to show me here the disk that I have available
i'm going to choose the 2 15 or 16 gigabyte USB flash drives and then all
you have to do is create a name so i could name it
raid before i do the raid tests or before i do that i just wanted to show
you guys a quick speed test on the disk before and after
so we can get speed test open up here
and we'll just run a speedtest on one of the drives their identical so this one
here so we got in about an average 18 to 20 read or even drop it or right sorry
we're dropping down right and then the reads about 30 megabits so kind of flat
line there is i'm probably not completely accurate but just as an
example so we'll create the read
a series say hello
I can do that hello goodbye Siri
ok see you later
once the rate is complete you can go done and then you'll be brought back to
the disk utility and if you go to this new read partition here you should see
both discs one of my discs isn't responding
just fix it
and so now my raid disk is up its kind of flaky with USB tracks
what can I say so with this you can see I have 31 gigs now so i have a 31 games
Strike so it'll right across both discs right here
you could add to the disk array or you can remove a disk if you had more than
two
if you remove the one it's pointless it's basically just what it would be and
then you can also run a repair which this is very important because in LOL
kappa con you could have a disk array of you know and you can do it by terminal
but you couldn't actually repair the disk something were to go wrong you
couldn't see which ones were online
so this really makes it easy to use and then delete of course you could remove
this raid and get your drives back you just have to reformat them
so one last thing we'll just run a quick speed tests across the new raid and see
how much faster it is using two drives instead of one drive
and we should see a bigger of at least a better speed improvement so you can see
the read speed is a lot better
the write speeds in and out might be the USB drives
so there you have it I did have a lot better results than that with this app
so you can see there the write speeds a lot higher
I think the application is just having a hard time measuring on being that's not
designed for being on the mac OS year so anyways guys thanks for watching make
sure you like this video subscribe to the channel for more and we'll see you
again next time
Cheers
