What the poster probably meant is the cheesegrater has integrated SATA drive bays which makes it "internal" and connecting more storage via PCI-express seems to be "external". Tehcnically however it is just the opposite.

Thanks for the explanation.
As to your second paragraph whether a drive is considered external seems to depend on the OSX in use. My system drive is a 1TB ssd on a pcie adapter card that I originally had just OSX 10.10.5 on it. After a while I decided to get brave and try out PT 11.3.2 on Sierra OSX 10.12.6 so I partitioned the ssd into two equal size partitions.
When I boot into the Sierra partition (which is my now normal working partition) and have Finder show external disks it shows both boot partitions on my desktop. If I boot into Mavericks and have Finder show external disks it shows neither boot partition.
Originally when I had just the one boot partition on that ssd I had it mounted in one of the regular drive bays. When I moved it to the pcie card it sped up something wonderful. So drive-for-drive pcie will always be faster.
