Hopefully I have put this in the correct forum location but here goes... Over the last couple weeks I have been moving about 40,000+ photos to a External WD My Cloud Drive due to the major issues with iPhoto having that many photos. After finally completing the move of all these photos I noticed a VERY SLOW connection opening up and viewing those photos on the external drive (just looking through Finder, not using iPhoto at all). However, when I go to my old windows computer the pictures seem to pull up much faster. After doing some research for the past few days I have been reading about some major bugs with Finder using AFP & SMB Network connections. I have tried all the suggestions about using a program called "Path Finder" to try and speed up that connection. It was a bit faster but not much. So, What I am trying to find out is: Is the issue with the slow speed related to the drive format (NTFS, FAT32, exFAT, etc..)? and, if so, will re-formatting the external drive to HFS+ fix the issue/bug with Finder?
