The mobo is an Intel DZ68BC Z68 Extreme Series. For backup I have an external one drive enclosure with an eSATA connection , the enclosure also came with a rear expansion bracket to provide an additional eSATA rear port. The mobo eSATA is controlled by a Marvel controller and is not hot swap capable. I have unused internal Z68 chipset SATA ports and could utilize one to connect the eSATA bracket and provide eSATA support from the Z68 chipset as opposed to the Marvel. The bios has an option to make any of the Z68 SATA ports hot swap capable. At that point I would disable the Marvel controllers since neither the eSATA or internal ports are needed. I have read many opinions to disable the Marvel if not needed and utilize the native Z68 ports if possible. Wondering if anyone has experience doing this or thoughts about the tradeoffs?
