Thought USB 3 Was Fast?

you are using front usb sockets to mobo?

No am using the USB 3 ports on back. Yes a very thick cable and deffinatly USB 3. Afaik the renesas drivers are correct and there are no updates or any other USB related drivers available on MSI website.

two more ports are shared with its USB 3.0 breakout connector that fit into a cases pci slot and connected to USB 3 header on the motherboard is what I meant.

Fitted the extra 2 USB 3 ports to the motherboard, ran HDTune this time and I get 29.8mbps read rate. Plugged it back into motherboard tested again and got the same 29.8. All my files transferred over night so will just bin the caddy lol

Your still al usb2.0 speeds

Yeah looks that way

quick vid of my 800mb file transfer, what you should be getting.

paradisiac · 12 Mar 2011 at 11:35

but with lots of smaller files its drops, like yours :

so i would do a few tests with different file sizes. i only really transfer 500mb + files so i benifit, if you only do small ones then eSATA looks the way to go.

Or buy a usb3.0 pci card

what would a pci card do?

If its you motherboard at fault here with not getting the usb3.0 speeds, a pci card would fix this.

its not the the mobo, its just USB 3 only picks up speed with large files, as my vids show.

But your file transfer still dosen't drop into the low 30s(usb2.0 speeds). That tells me either the motherboard or caddy isnt in usb3.0 mode with "thunderflash". So its time for process of elimination if he wants to solve the prob

paradisiac · 12 Mar 2011 at 13:54

if you watch the second vid it goes down to the 20s for the smaller files.
best thing i can suggest, is again, just move over small files, then medium, then large and see if the speeds increase the bigger the files. mine does.

I used crystaldiskmark and tried different sizes it goes between 29 and 33 mbps for sequential read and slightly less for writes. Will just leave it to run over night I think. There was another 2 ports that can be put into a slot on the case and attached to a header so will try that tomorrow.

I can more or less guarantee something is running in usb2.0 for "thundeflash" to get this result, as my usb2.0 hdds never goes over 34mb/s copying stuff, accept at the beginning for a few secs, but thats microsoft for you

Isnt it the calculation of the speed is the Average speed of ALL the files and not a bandwidth test.

Not much that can be done except transferring SSD to SSD.

no its the file its copying at present, as the mb/s goes up and down depending on the filesize that its copying

Ah wait a minute, erm just tried moving 1 film (1.5gb) from my main storage drive to the usb 3 external drive and got 120mbps for 1st 3 quarters then down to 30mbps for the last quarter. Then moving the same file back from usb 3 drive to internal storage I get 31mbps. So the benchmarks don't really work as such?

paradisiac · 12 Mar 2011 at 19:14

hmmm.............normally they do, but i prefer to use real life tests rather than benchmarks. if it works with the larger files then all is well, usb 3 just seems poor on small files.

thunderflash · 12 Mar 2011 at 20:04

it is very strange paradisiac. the figures in windows say 120mbps etc but because the last bit goes slow it doesn't really make any difference. I just moved a 950mb file from Internal sata to the USB 3 sata HDD and it took 21 seconds, moving it back again took 33 seconds. My math isn't good but I think I am write in saying that's 45mbps and 29mbps?
