    How to view allocation unit size? HAWnQ8bO6CH20FERvJKmARD5WRQSNPht6EPd7CSnSWI.jpg

    When I view properties for a USB flash drive, I can see space used, free space, capacity and file system type. It does not display allocation unit size though. So where do I go to view that?

    Disk properties

    Allocation Unit Size

    For SD cards that are 32GB and smaller, select the file system FAT32 and allocation unit size 32 kilobytes.

    For 64GB cards and larger select the file system exFAT and allocation unit size 128kB.

    If the phone formats the card this is what you will get.

    Allocation Unit Size

    What is the best Allocation Unit Size for an ex-FAT formatted MicroSD card.

    I am using a Microsoft Lumia 640XL and i need a responsive SD card while capturing HDR images.

    I am using a Lexar 300x series MicroSD card.

    Thanks and Regards,
