UPDATE:

 
The card works! Michael at Firmtek was extremely helpful in troubleshooting solutions and the proper driver in the end (the card registers as a SCSI device, which makes it different from other seritek/sonnet SATA plug n' play solutions). I am using SCSIProbe to make it auto mount my hard drive.
 
I'm currently using the 1SM2 as a go between for samples/ableton files between my laptop and my home DAW.
 
I can highly recommend this device and Firmtek!
