indiandragon Posted August 20, 2012 Share Posted August 20, 2012 Guys, since OSX Mountain Lion brings in native USB3.0 support, did any one try the seagate USB 3.0 upgrade cable package with express card adapter? According to seagate KB (http://knowledge.seagate.com/articles/en_US/FAQ/217951en#13) , The Express card Adapter would provide USB 2.0 speeds in OSX as there was no USB 3.0 support, but since now we have USB 3.0 support does the adapter work and give better speeds than before . I know the limitations of Express card bandwidth, and that it cannot give full USB 3.0 speeds for PCI based express card but a USB 3.0 support means a definitely higher speed for my 1TB seagate GoFlex Freeagent HDD.
