Wow, I’m pretty impressed. Read up on UASP (USB Attached SCSI Protocol?) which runs SCSI over USB in an alternative mode. Supposed to be supported natively by Windows 8 and Mac OS X  and Ubuntu as well, I popped in a slower Corsair 960MB SSD to see. Here is what I got using the Blackmagic Speed Test:

  1. iMac 2007. This is a USB 2.0 system and with BlackMagic Speed Test, I got 30MBps read and write which is about the limit of USB 2.0
  2. MacBook Pro 2014. This has USB 3.0 and with that I got 650MBps read and 710MBps sequential read. That’s about the theoretical limit of the SATA 6GBps controller that is there. 

Net, net, the thing cost $13 and you can stick a SSD drive in there and have quick temporary backup or an extra drive. Pretty convenient and certain great as a high mix USB boot drive for instance.
Also, the USB 3.0 is definitely faster. I have the new USB 3.0 based Kingston SE9 and it is 50MBps write and 120MBps read while the older USB 2.0 SE9 is 13 MBps write and 22MBps write

I’m Rich & Co.
