Sandisk Extreme 64GB - Slower write speeds after system format

However, how weird is it that SanDisk doesn’t care to provide a Tool to help users store >4GB files

on the most common File System?

Actually they do.  It’s called 64GB flash drives formatted in the factory as exFAT, which supports files larger than 4GB.  Unfortunately they haven’t found ways to prevent users from blindly reformatting them with even trying them.  Then complaining about the drive they screwed up.

(Silly ideas these customers … )

That’s one way to describe them. :smiley:

BTW Current versions of Windows have support for formatting removable drives as exFAT built in.  No need to hunt for something else.  :wink:
