AFAIK, flashdrives operates the same as ssd's. while SSD's and pricey flashdrive (e.g. Sandisk Extreme) support the trim command to erase occupied space the sheaper flashdrives do not support trim, what means they get slower over time. deleted contents still remains on that flashdrives what means writing new data leads to an erase/write cycle. *I* long (not quick) format those slow flashdrives under windows. - I currently don't know if the gnome disk has an equivalent for "long format", I guess it's the "fill with zero's thing" - _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@xxxxxxxxxxxxxxxxxxxxxxx Do not reply to spam on the list, report it: https://pagure.io/fedora-infrastructure
