It would work in MBP, but Samsung does not provide utility for Mac. You cannot even update the firmware without a Windows system. If you can first hook it up to a PC to update the firmware (the latest one is F07 from December and the current batch is shipped with F06), it would be fine for you MBP. The new firmware improves performance after prolonged use when files are fragmented.
Thanks for the info, and I have an old Windows laptop I could use, so that should be fine. I'll probably wait til another deal with the kit for $150 comes around
