Course speed SSD at 40 MB/s with USB - C cable

I recently bought a Samsung T3 USB - C SSD drive for use with my MacBook.

But right now I am facing a problem of course speed on that:

I bought it used with my MacBook retina 12' because of the support of USB - C

But there is a real problem for this drive to use with cable USB - C for USB - C:

If I use the USB - C to C USB Apple cable, I get only speed USB 2.0 which is capped at 40 MB/s in and out. As the 1-3 photo shows below.

If I use it with USB - cable USB - A C I USB 3.0 speed of 425 MB/s 400 MB/s on. But the downside part is for MacBook, I use a USB - C for the USB - A adapter as shown in photo 4-6.

If Apple is any course speed cable USB - C or Samsung should take the blame that send the wrong information of speed USB 2.0 for Macbook?

Use with direct cable Apple USB - C (I tried another cable USB - C like same problem anker/Chotech) cable is not the problem

You can see that the speed in the information system is listed as USB 2.0 at 480 MB/s

A speed test to confirm it is limited to the USB 2.0 standard:

If I use a USB to adapter USB - C and use the USB - C for cable USB - A on the SSD. It will run at full speed:

You can see that the speed in the information system is listed as USB 3.0 to 5 Gbps

A speed test confirm this works:


The USB - C to C USB cable that comes with the MacBook is not supposed to be used for data, this is to be able to only. You will need to buy a USB - C data cable.

  • Big problems with USB devices

    Since I upgraded to El Capitan I have several, serious problems with USB devices:

    1 USB hard drive: everything by watching a video from an external hard drive, the hard drive will be to disassemble all the minutes, the video will be of course hang and it takes 45-60 seconds until the drive reconnects. I also can not boot from any external hard drive more. Booting from a USB key works fine.

The overview of the system he sees when connected via USB, however he is not recognized and so I can't transfer data files. Also, it makes not a difference if it is connected via a USB hub or directly, the two versions do NOT work. In the Finder preferences, all devices are controlled to display on the desktop.

  • X 220 and Mini Series 3 with USB 3.0


    I am recently received a Mini Series 3 with USB 3.0 for my laptop company ThinkPad X 220 Windows 7 64 bit.

    However, after installation of the USB 3.0 driver downloaded from the Lenovo Web site, I still do not see USB 3.0 in my Device Manager device.

    I have also some test using an USB3.0 external HDD but the USB 3.0 port seems to have exactly the same speed as all the other ports.

    How can I activate USB3.0 on this Docking Station?

    Thank you


    ThinkPad X 220 with i7 (i3 and i5 has usb 2.0 ports only) has a single USB 3.0 port, but the way it is connected through the motherboard, it is unable to support port additional usb 3.0 from the dock.

  • The Sansa View will work with USB 1.0?

    I'm buying a Sansa View 8 GB as there are has exceptional offers out there right now.  However, I don't have USB 1.0 on my computer (in XP), can I use the Sansa?   I realize it load probably wouldn't work - I would just buy a power adapter.  I am concerned about the question to know if I can transfer files, etc.   If it's just the speed-, not a deal breaker.  If this is all simply does not work - a lot more thought will have to go into this purchase possible.

    Thank you!

    Thanks for the reply!  I did go ahead and buy one with the Geeks - as they had a very good price.  It should be here tomorrow.  I also bought a power adapter.

    I'll look into putting in a USB 2.0 card.  I had considered before but didn't know if it would support my motherboard.  Just getting worse - my mom has a new computer with USB 2.0 in the next room.

    I've already knew the earbuds and have some that I had bought to replace the one my Zen.

    Model: MA146LL

    Size: 30 GB

    Version: 1.3

    It has a color screen and touchdown.

    Thank you

    You can use two types of '30-pin' USB docking cable that Apple has officially sold as spare parts.  What is the current always sold

    In the list, under compatibility, product of 5th gen iPod is listed.

    The older type has a larger plastic end of host connector, but the connection point is the same as the new type.  With the older type, you press the sides of the connector to release the hooks.  The new type is held in place by friction and two 'bumps' instead of brackets; Simply pull.

    Third party reputable sources also options work fine.

  • can't get out with USB itune icon

    using ipad unable to leave the itunes icon with USB showing

    Hello, Conmare.

    Looks like your iPad slipped in for some reason Recovery Mode any. Which indicates something happened and you will need to reinstall the iOS. I'll be happy to help you with this.

    If you see the connect to iTunes on your iPhone, iPad or iPod touch screen

    Connect your iPad using the lightning cable provided with your iPad to a computer with iTunes installed on it and see if iTunes responds. If so, that's fine! Just follow the guests.

    If iTunes does not respond, disconnect the iPad off the iPad by using button on/standby (power). Once it is off, press and hold the Home button and reconnect the iPad to the cable. Don't release the Home button until iTunes responds. Still, if this is the case, follow the prompts.

    Once iTunes has reinstalled the iOS again, you can use a recent backup, as you did to reset your iPad. If it is not all recent backups, configure as a new iPad and sign in iTunes and App Store and iCloud. You can synchronize the information that is available. Another thing, I'm afraid, is lost.

    Nice day!

    You can connect otherwise?  USB or FireWire or love at first sight?  You can connect both machines and start the one you want to transfer to target disk mode.  If your other machine is up and running with an account on it and you just want to move files, you can simply drag and drop the FRO the machine mounted TDM, or you can use the migration wizard.

    Or, if the other machine still starts and runs, you can start both computers and connect to the same wifi network and share the hard drive like machines on the network.  Access them in the finder on the new machine files and drag-and - drop, or use the wizard migration, on wifi.

  • Portege R600-140: message says: device would work better with USB 2.0

    R600-140 win 7 prof
    I plug in a device of capture usb video and a popup appears saying (roughly)

    + This device would work better with USB 2.0 - Click here for a list of usb ports.

    I thought all the usb ports 2.
    I just checked the drivers in the Panel, and I thought they are all up to date.

    The laptop supports without a doubt USB 2.0 ports.
    I guess that this message can appear for many reasons: for example the USB device malfunction.
    Also the problem of USB port could be responsible for such error.

    So as the first workaround I recommend you remove the USB hubs and controllers in the Device Manager list.
    Open the Device Manager, look for the controllers and USB hubs and uninstall the driver.
    Reboot the laptop

    Usually the system will begin to recognize USB devices.

    Note: during this procedure, all external USB devices must be disconencted
