In regards to FAT32, I ran a full test at pcpitstop.com and came away with this result:
One or more partitions are using the NTFS file system. Although this file system offers many good features such as encryption, security, and improved reliability, it is often slower than the FAT32 file system. However, we do not advise switching back to FAT32 just to increase disk performance scores.
I'll be switching back to FAT32 when I figure out how to do it.
