    OK, so I just dropped an SSD into a USB3 enclosure and when I plug it in it does nothing. Finder just spins. I load up disk utility and it does the same thing. Any application that can read the disk just siezes up.

    Anyone know whats up?

    I was able to read, format and write to the drive in windows...but not in Mac. WTF???

    I wrote 9GB of data to it in about 50 seconds. It was averaging about 125MB/s but maxed at 225MB/s. But I can't use it on Mac side, which is where I need it!

    Does anyone know how to fix this??

    Same here with my intel x-25 and usb 3 enclosure.. no response. But my 3.0 WD My Passport works fine and transfers extremely fast compared to the 2.0 version I had before.

    Do you have any references for this?
    I bought a OCZ Vertex 4 256GB and a usb 3.0 SATA III case off ebay.
    I can format and use the drive, but under heavy load it hangs.
    OCZ said they are looking into problems with their drives and enclosures. I tried 3 other enclosures and the drive wasn't recognized at all (in one case intermittently.)

    currently using a Crucial M4 256gb SSD with a Seagate USB3 Upgrade Cable.

    Works perfect even under heavy loads. I run Virtual box from it storing the virtual machines on the SSD.

    I have had 6 virtual machines running at once and had no problem with it.

    Is that cable a SATA III?

    I am having similar problems.
    I tried 4 cases. 2 didn't work. 1 worked intermittently.
    One almost works but hangs under heavy load.
    The drive is an OCZ Vertex 4. They have admitted there is something they are looking into with USB 3 enclosures.
