    USB3 HDD slower than ext laptop HDD USB2==>SATA cable


    Hi there

    WD passport (small self powered 2 TB USB3 drive) has appalling performance compared with an OLD laptop HDD that I connect via a USB2==>SATA cable to USB2 port.

    Same file (2GB mp4 video) copied to a directory on the SSD.

    External laptop HDD connected via USB2==>SATA cable to a USB2 port -- 41 Mb / sec on average -- Ok for a USB2 device of this type

    USB3 device connected to the laptops USB3 port = 31 Mb / sec on average. Same file !!!

    So obviously there are USB3 devices that don't perform at anything like the rated USB3 speed -- so don't buy a USB3 self powered portable drive and assume it will give you much better speed than USB2 - it won't.

    Some might do but a lot of the smaller self powered "passport" types will leave you less than impressed - especially as Laptop HDD's aren't renowned for their speed anyway !!!!. So a USB3 drive performing worse than a laptop HDD -connected externalyy via a USB==>sata connector ??.

    Is USB3 really that good or are we just being conned to buy "newer hardware"

    Cheers

    I have an older WD Passport with USB 2 and it runs on large files around 40 Mb. I also have a new WD Ultra Passport with USB 3 and it runs over 110 Mb.

    Yes, USB 3 on my PC runs very well. Transfer speeds are only slightly slower than on the internal SATA III connections.

    Hi there

    The newer drives might be OK but the two WD pocket size self powered passport 2TB USB3 drives I have are Terrible for transfer times !!!! - I'll have a go with a USB3 thumb drive and see what happens,

    On USB3 I should be expecting at least an average of 90 mb/s - especially when my OS is running on an SSD.

    I use a USB 3 HDD dock to connect older SATA HDD's to my system. It works great.

    USB 3.0 transfer speed is one thing. A hard drive write speed is another and that's probably where the bottle neck is.

    Have you got the correct USB3 drivers installed, otherwise I suspect it will default to USB2 speeds ?

    Try this program and it will show you your USB ports and what speed your drive is connected.

    Jimbo,

    Not sure if it will do what you need but NirSoft - freeware utilities: password recovery, system utilities, desktop utilities has View any installed/connected USB device on your system which may help.

    Note - A lot of AV suites don't like the Nirsoft stuff but I've been using them for years without issue
