so today I have a test that's very interesting to
me because I copy a lot of data around so
what I have here is my little chart that I'm going to make and I'm going to be
looking at the performance of various USB chipsets and various drive solutions
so I have three different solutions that I'm going to be using the first of which
you can see here is I'm going to do a oh
did I write one terabyte oh boy it's
been a long day already Guys these are all you know what let's just yeah these
are all 1 Gigabyte file copies okay so the first solution is a USB 3 seate
glex um adapter plugged into a patriot
Wildfire drive so this is one of the highest performance drive it's pretty
much the highest performance drive on the market so we're going to see what
kind of thorough put we can get using that next we have a Seagate free agent
glex this is a 5400 RPM storage shrive this is also hooked up to a usb3 chipset
here at the back the one I have here is the native a75 chipset one I'm going to
compare that against the as media one which uh based on that it's just started
turning up and it's on an assus board I'm guessing it's their own kind of custom thing and it's probably going to
turn up on other assus boards in the future so the performance may be
relevant I'm also going to test against the ever
popular Renaissance so this is on uh some of the higher end boards
particularly they used to be NEC usb3 chipsets so you can see I've got one
here on the z68a gd80 and finally I'm
going to test against USB 2 so I'm going to test against Intel's USB 2 controller
just because it's a much more known quantity than the one on this a75
chipset the last Drive configuration I'm going to test is the mushkin Ventura Pro
this is a USB 3 drive and I'm going to find out what the difference in
performance is between a high performance USB thumb drive like this an
Extreme Performance SSD on USB 3 and a
regular hard drive on USB 3 across all these different platforms so I'll be
back with results or with any abnormal findings throughout the testing here so
the first round of testing on the ASUS a75 board is done so on the a75
controller I accidentally wrote These in the wrong box I got 34.5 megab per
second consistently and I'm just timing this on my iPhone while I do the
transfer so I got 29 seconds 29 seconds and 29 seconds to transfer my 1 GB file
so I'm going to go ahead and assume that's a chipset limitation on large
file transfers on the as media controller however I got 125 mbes per
second on the glex with the Wildfire SSD
so let's assume that that's pretty much the limits of what we can achieve with
the this usb3 controller and then next we have 67 megabytes per second on the
one or on the mushkin Ventura Pro remember that's the USB 3 stick and
finally 50 let's call it 53 megabytes per second on the drive with a hard
drive as opposed to a solid state drive
okay so what I'm going to do is I'm going to change motherboards here change platforms going to switch over to my
Intel platform and we're going to test the usb2 for reference as well as the
Renaissance controller which you can see down there somewhere
it's right there all right well I'm done
most of them so I'm just going to run my last test here and I'll talk a little
bit about the results that I've seen so far while it's running so yeah it's not
sophisticated but yes this is actually how I'm testing it I press stop when
it's done transferring so here we go so I've tested the NEC Renaissance however
you pronounce that I have no idea controller you can see that you okay a
few things become fairly apparent right off the bat here number one is is that
the Wildfire is not a bottleneck for any
of these interfaces I mean we're we're not even seeing anywhere near the limit
of what that thing is capable of doing next is that the Ventura Pro seems to
max out around there we go it's done so that took oh surprise surprise 37 so
that'll be around 27 megabytes per second okay so these
are all in megabytes per second okay so the Ventura
Pro is uh limited to 67 megab per second
cuz you can see these two controllers are both capable of higher numbers up to
125 or 111 megab per second with the
glex interface on the Wildfire Drive
okay uh down here you can see that with the mechanical drive we don't see any
higher than these are both 53 mby pers second and we can also see that the a75
usb3 controller is bottlenecking pretty much every solution here the USB 2
controller performs consist consistently with all of them because once again it
is the bottleneck not the drives themselves and the Renaissance one that
appears to be the limit because we see that the golex Wildfire performs better
on the as media controller so that Asia controller is actually looking pretty
darn good my results are not scientific and they are not accurate to within 01
of a megabyte per second these are all approximate number so take them with a
grain of salt but there you have it the Renaissance controller is approxim Ely
four times faster than USB 2 the as media controller is about another 10%
faster than that and then the a75 controller seems to bring up the rear
here as far as the usb3 controllers go so thank you for checking out my video
