Does JetDrive USB-SATA adapter support UASP mode? Category : Specification / Capacity / Performance Yes, JetDrive USB to SATA adapter supports UASP function.However, UASP function can only work on Windows 8 or OS X 10.8 or later. A UASP driver is required for Windows 7. Is the answer helpful? Related OS X 10.10.1 to 10.10.3 (Yosemite) do not allow us to enable/disable TRIM function via a third-party tool. Will this affect the SSD performance? When I run the Apple Hardware Test (AHT) before installing OS on the JetDrive, I get an error message saying “4HDD/ 11/ 40000000: SATA(0,0)”. How can I solve this problem? Is any of the Transcend JetDrive series supported on new Mac models?
