Jose_49 Posted March 28, 2015 Share Posted March 28, 2015 Sup people! yesterday I was pushing some huge 8 GB .iso to my USB 3.0 flash drive. I passed it to a friend's laptop: MSI GS60, which has USB 3.0 ports. The copying speed from my drive to his PC was 242 MB/s (stable) (Currently running Win 8.1 stock) . I was astonished to see that huge speed and decided to do it with my laptop (Lenovo Y510p @ Windows 10 B. 1041). Poom! It started swiftly @ 242 MB/s, but after a couple of seconds it dropped to 68 MB/s. At first, you could think that this is a power problem, meaning that the USB port doesn't have enough power to handle it, but I have an external USB 3.0 hub (ANKER - connected to AC), by which I think that it eliminates the AC problem... Could anyone explain me why is this? Am I having driver/Windows problems? Or is this normal? Any explanation I'd be greatly appreciated. Thanks a million!

There are Intel USB 3.0 ports and there are others such as those that use the NEC chipset. It's possible that you tested it out on 2 different controllers hence the difference in speed. You would have to look into it further by identifying your USB controllers for a start. There are other factors like the destination hard disk speed which would influence results. Windows 10 having beta drivers might not give the optimum results. Aergan and Jose_49 2 Share Link to comment Share on other sites More sharing options...
Aergan Posted March 28, 2015 Share Posted March 28, 2015 Are you connecting USB 2.0 devices to the same hub / controller? I've recently had to split mine out on my Z97 after I discovered similar performance issues which were due to mixing devices. I find the same issues regardless of OS (Windows, OS X, Ubuntu).

LittleNeutrino Veteran Posted March 28, 2015 Veteran Share Posted March 28, 2015 Another thing to consider is you will always get faster read times than you will write times. Jose_49 1 Share Link to comment Share on other sites More sharing options...
