Hi All, I am getting my Late 2011 17" MBP back from repairs soon & it was running Mavericks 10.9.5. I would like to upgrade to Sierra but I have been told by some of the good folks here that it would really be best if I got a SSD with Sierra instead of the regular spinning drive. Problem is I need lots of storage so was looking to max it out at 4TB of regular storage via 2 x 2TB HDD's. Now, since regular HDD's may struggle with Sierra & I cannot stretch to large capacity SSD's, I would like to know if it is possible/feasible to: 1) Put a smaller SSD (256GB or 512GB) inside the standard HD Bay inside the MBP (leaving the Optibay alone) 2) & then get a large capacity portable or desktop regular HDD, move over as many files as needed on to it & then connect it to my Time Capsule. 3) I am thinking/hoping by doing this, I might be then able to "Connect" to this external HDD via/on my MBP to access files either by WiFi or Ethernet cable from the Time Capsule. Is the above (or anything similar) an option - If not can someone suggest an easy alternative? I was thinking this would allow me to leave the DVD drive alone in case I might damage or mess things up in attempting to remove it! Many Thanks!
