Good throughput but, there maybe issues with power mgmt. (not sure if card or cables yet)
on January 3, 2016
On my Macpro5,1 running OS X 10.11; Seems to work however; I've noticed some issues with drive disconnects when Powermgmt activities take place.. (e.g., sleep). I keep getting messages that indicate a drive hasn't been properly ejected. Don't see that with stock USB or SATA.
