Why exFAT is a big no ? Pls.explain.
Also experienced that once flash drive is formatted in NTFS, you cannot safe remove it quick. Even after MS Windows close the copy /move window, data will pending to be written on the drive. Removing fast, without full 'Safely Remove USB Device" will either cause drive damage or data loss.
Also, the high write cycles of NTFS which can increase wear of flash drive is a concern.
EXT3/4 can only be used with Linux, so how OP can use it with windows which is a major OS in use ?
