Not Thunderbolt, but SATA III. I have a PC workstation, and bought a PCIe RAID controller card from HighPoint, a 2720SGL model. I use only 4 of the 8 connections. This setup runs Windows and Photoshop and everything like a dream. Everything that does I/O access is just instantaneous, and it just doesn't load up - I can run any number of things. It's blessedly quiet.

This second benchmark is a "real world" test with reading/writing and random access occurring.
