I am excited about the potential advantages of converting my current macOS SSD HFS+drive over to APFS when the first public beta arrives, but it has led me to a question. I have a few NTFS external drives (2x2Tb, 2x4TB...files sizes from 2GB to 35GB) that I have long wanted to convert to a more Mac friendly format, but without data loss. I know that APFS is optimized for SSD, but will it be possible for me to convert NTFS to APFS without data loss? Is it too soon to know at this point? Thank you!
