Hi guys, Situation: I have a MacBook Pro 9,1 (mid-2012, 15 inch; 2.6 GHz i7, 8GB RAM) I have an internal 3G OWC SSD right now (max write read speeds of around 240 MBps), and an external OWC I mainly use the laptop to record music with ProTools 12 (hence the need for fast read/write speeds) I'd like to 1) increase the read/write speeds from ~240mbps to ~500mbps (planning on buying OWC's 6G SSD) 2) increase the hard drive memory with a fast read/write drive Hardware Considered OWC 6G in the main drive OWC 3G as a secondary drive Possible Solutions 1) UBS 3.0: Use the USB 3.0 connection to connect to the 6G SSD, but I would prefer not to use the USB drive for an external drive. 2) SATA: Install 6G SSD in main drive, install 3G in optical SATA connection drive, however, the optical drive calls out a maximum negotiated speed of half the main drive (1.5GB vs. 3.0). If that is the case, the max speed I could get would be 130-145 MB/s using SATA? 3) FireWire 800: Same as #1, but FW800 instead on the connection My hunch tells me the SATA connection is faster, but the negotiated speed is keeping me from doing this. Any advice would be appreciated.
