[SOLVED] Slower than USB 2.0

[Headonastick]

I've only got a wireless dongle plugged into one USB 2.0 port on a machine I've just bought and I've read that having too many peripherals plugged in will have a cumalitive effect on speed, but 2-3 Mbps for a USB 3.0 is surely far too slow for a file only 1.4 GB when transferring to a SanDisk Ultra 32 GB USB Flash Drive isn't it?

If you have motherboard (usb 3.0 host controller driver)drivers, you should not get those kind of speeds....

Is it possible your pen drive to be faulty or problematic? (try different pen/ssd/hdd drive)
Also write the transfer speed in MB/s because its confusing ... i don't know if you know what is the difference between MB and Mb ..... You computer is showing you the speed in MB/s so you calculate it afterwards to Mbps?

I've just used the pen drive through a USB Host and got 10-11 "MB/s" which is slightly faster, but still I was expecting better than that.

I don't know the exact model of the pen drive, but here is a comment on it about its speeds (the pen drive speed)

SanDisk Ultra USB 3.0 flash, Black 32 GB

I find value in a lot of SanDisk's products in general, but this one isn't great. I ran fill volume speed tests and got 9MBps write (peak 11.5, low 3.59. The average was a solid 8.95MBps over 1000 sample files.) Read speeds were better at 39.7MBps, with only three very small dips to 23MBps.

Your pen drive speeds are fine and your USB 3.0 is bottle-necked by the speed of the pen drive
