It could also be a hardware issue as Clintlgm mentioned, but would be inclined to think the USB ports would usually not work at all if this were the case, so it is probably worth investigating more.Įdit: Wondering if it could also be bios-related, but probably not worth fooling around with if the unit is out-of-warranty.
I find that mine transfer speeds with USB 3.0 are just a little bit slower that eSATA 2 speeds with the same hard drivesĬlintlgm (and DirtTrash78), I may be wrong, but if USB 3.0 ports on both the left and right sides are affected, I would think there is still a fair chance of a software issue, but really depends on what kind of Windows image DirtTrash78 is using or the condition of the software. Many people have issues with USB 3.0 on the Left side those are on a daughter board the ones on the right side are part of the MB I for one do have issues with the left side so I just use a 4 port hub from the right side front port.
Hmm then you must have a hardware issue, in the beginning back in 2012 I had issues with USB 3.0 but I resolved them and never really had any further issues the latest Intel USB 3.0 drivers on Win 7 and the native driver in window 8 and above. If you haven't checked the USB 3.0 ports on the 'right' side, check them to see if they work any better than the left USB 3.0 ports in your notebook. I guess it is what it is, damn I hate that saying.īy the way have you tried comparing the speeds of the USB 3.0 ports on both the left and right sides? After a ton of research I am seeing a lot of ROG customers stating the same issue regarding 3.0. And everything I build has always had nothing but ASUS components, where applicable. This and other small issues are steering me away from newer ASUS ROG notebooks, sad to say. I am a Network/Computer Engineer and the systems I am refering to regarding past speeds are HP's, Dell's, Toshiba's, and my own custom systems I built that always had various Sabertooth boards in them. It doesn't matter which drives used 2.0/3.0 hard drives and/or flash drives. Both systems are identical to 2.0 speeds. On my last two "G" notebooks G73 and G75 those speeds have been horrific, aside from 2.0 which hasn't changed, seeing every 3.0 device identical to that of 2.0. And for 3.0, same size files, I'm used to seeing transfer speeds in the range of 60-100mbps. And I have already gone through and uninstalled Charge Plus, and disabled legacy support.Įvery system I have ever owned I've seen 2.0 speeds, for files larger than a few hundred MB's, in the range of 20-30mbps.
