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.
 
I read a few sites saying there is an issue with usb3. Hopefully it will be fixed soon!

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?
 
so nobody else is having this problem?

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.
