    That's pretty normal speed for a USB mass storage device and a large file.
    I have a Renesas USB 3.0 card, here's my Win7 results copying to a USB 3.0 Transcend flash drive:

    Yep, your results are poor:
    1.jpg
    USB:
    VIA USB3 Controller Driver v6-1-7600-4301
    Patriot USB3 Magnum Supersonic 256GB
    HDD:
    Marvell MV91xxxx SATA3 Controller Driver v1-2-0-1039
    HDD Seagate 4TB ST4000NM0033-9ZM170 SATA3 (TrueCrypted - about 3% slowdown)

    You should discover, which Renesas do you have:
    μPD720200
    μPD720200A
    μPD720201
    μPD720202

    I can send you utility, just enter to command line:
    Code:
    W200FW35.exe /srom ?
    Then update fw (v4-0-2-1-0-3 or v3-0-3-4 - depending on version) and driver (v2-1-39-0).
    It corrected my Renesas speeds nicely on my nbook.

    Have you turned on disk cache in the properties?
    I think it's disabled by default on removable drives.
    The only downside is that you would really want to click the safely remove button any time you wanted to disconnect it.

    Does not matter still get over 200MB/s reads and 190MB/s writes on my Sandisk Extreme 64GB on same controller make (not sure on your model).

    I have latest FW and driver for it from stationdrivers.

    I think I replied to a topic before like this with pics, there is an issue if that device is USB 3.0.

    If you have plural Renesas controllers on your Mobo (2 or more) its a PIA to update the FW since they messed up the installer a few versions ago.

    Let me know if you get issues as there is methods to get them installed.

    My Asus Z68 Rog Mobo has 2 controllers USB2.0/3.0 (not counting the native Intel chipsets ones)

    Here is what mines looks like:

    Yep, you are running MS drivers there. BTW: USB Root Hub (xHCI) bellongs to Renesas too...

    ^^ I seen that also and was sure even with the now native USB 3.0 support in Windows it does not let my controller run properly till I use its own drivers.

    I assume its the Intel controllers that have native USB 3.0 Windows support but would guess Intel would have drivers also.

    Only for Windows 7; not for Windows 8.x.

    I assume you mean 30MB/s? (Bytes not bits)

    If so that's about normal for USB 2.0, a good Intel controller and fast device will get 35MB/s in real life use due to shared resources and overheads.

    I have heard some claim 40-45MB/s on USB 2.0 but TBH I have never seen it and doubt it.

    But on a USB 3.0 controller possibly a USB 2.0 device may be little faster as some claim like an external HDD that is capable of far faster than USB 2.0 speeds as it is really an SATA HDD inside a caddy.

    Amazon claim your S2 is USB 3.0 but other sources state the S2 is USB 2.0, the S3 is USB 3.0, do you have a S2 or S3?

    That is nothing terrible, key is if:
    Code:
    W200FW35.exe /srom ?
    is able to detect your device.

    The error above happens, if:
    1. You are running MS drivers.
    2. Your FW is newer than the utility itself.

    Similar but w/ a another Renesas Electronics host controller & +2 Renesas Electronics USB 3.0 Root Hub (entries).
    Driver version: 2.0.26.0

    This is my USB 3.0 vs USB 2.0 speeds & comparing Windows 8 vs Windows 7 in the mix.

    Note: the lower results testing done using NirSoft USBDeview USB Port speed testing software, wont run in Windows 8
    The upper results are from Windows Explorer w/ details expanded
