However When plugging my USB 2.0 flash drive into the USB 3.0 port of one of my laptops running W8 Im only getting around 2.5 kB/s! sometimes if its a larger transfer it will trail of to nothing at all!!
The strange thing is when I plug it into a W7 laptop's USB 2.0 port transfers run at expected speeds (i.e. I dont notice it being overly slow but I didnt look at the numbers).
Neither of the laptops have the USB performance set for speed rather than safe removal, nor do I want them to be as I have found the gain in speed to be minimal yet the payoff in damaged drives does indeed rise quite a lot.
Even when it is transferring, looking at the windows transfer visualisation, it shows continues peaks (the peaks still only being a few kB/s) and drop offs instead of a rise and then a continuous(-ish) level till a final fall-off that one would expect.
Neither disk manager nor device manager (or event logs) show any issue with the drive r anything else.
Sometimes the speed increases if I push down on the end of the protruding USB drive, but other times that seems to slow it... A current transfer of mainly .c files is running at only 637 bytes/s! Any knowledge on how to fix this? Thanks
P.S. Yes I have looked at a lot of the other Q's regarding slow USB transfers - they all (as far as I could make out) concern minor increases in the MB/s range.
The symptoms suggest that the USB 3.0 port on one of your laptops needs to be cleaned. – Andrew Morton – 2018-08-05T16:17:09.853
E.g. it just took me over 10 minutes to copy a 10 MB folder to the flash drive - copying the same folder from the drive to the w7 machine took a few seconds :( – Toby – 2013-06-30T14:20:02.520
1Do you have any kind of other software running on windows 8 machine that could be slowing it down? Something that takes up 100% cpu, a different virus scanner? Also check to see if there are new drivers available for the usb controller. – Scott Chamberlain – 2013-06-30T14:48:01.723
Normal idle for CPU on this sys seems to be 3-6% I do have one or two large applications on this sys (2 x IDEs) other than that though I havent got much else installed on it and I cleaned 95% of the crap-ware off as soon as I got it. Drivers all up to date... – Toby – 2013-06-30T15:11:50.057
2Question, do all USB 2.0 devices work that slow on the port, or is it just the 1, and have you tried a USB 3.0 device, on the 3.0 port. – user88311 – 2013-06-30T17:20:17.350
@user88311 Just tried another 2.0 flash drive and got solid average 9MB/s speeds, still a bit low but MASSIVE compared to what the other drive gives, thought the actual Usb plug on this one is better also, the problem one is one of those that only have the base with the tracks on it... (I have no 3.0 devices yet) – Toby – 2013-07-01T19:21:28.360
@artistoex what the...? – Toby – 2013-07-01T19:21:49.500
@toby Just teasing. I mean Windows 8 does disappoint at times. – artistoex – 2013-07-02T07:56:01.097
