Everyone seems to be swapping their internal HDD for an SSD. Has anyone swapped out their 1TB HDD for a 3TB or 4TB HDD? I have read that in previous iMac models there were fan issues if the HDD was swapped for a HDD that didn't have the correct firmware, i.e. Apple Firmware). Is this still an issue with the 2012 iMacs?? Curiously, from what I've read, swapping the HDD for an SSD doesn't cause any issues with the fan. Would someone please corroborate. Next question external storage. I have an Icy Dock RAID with eSATA. How can I take advantage of its eSATA connection using the new iMac? The Icy Dock is a RAID device with port multiplication. I have seen some USB3 to eSATA adapters but there seems to be an issue with port multipliers. Thank you for suggestions.
