Hi there, I wanted to quickly share my results with the Seagate GoFlex Thunderbolt Adapter paired with a Crucial m4 128GB SDD, OCZ Vertex 4 128GB, and an older OCZ Vertex 2 128GB SSD. The drives are simply connected to the Seagate GoFlex Thunderbolt Adapter via Apple's expensive 2m Thunderbolt cord during these tests. The tests are done with the Blackmagic Disk Speed Test app. First Test: Crucial m4 128GB SSD (000F firmware) Write: 195.0 MB/s Read: 386.0 MB/s Second Test: OCZ Vertex 4 128GB SSD (v1.5 firmware) Write: 352.8 MB/s Read: 368.7 MB/s Third Test: OCZ Vertex 2 128GB SSD (v1.37 firmware) Write: 105.6 MB/s Read: 207.8 MB/s I'm installing the Crucial m4 as my boot drive and I will be doing a clean install of Mountain Lion, so I will re-run the test and post those results as well. Cheers!
