The udev rule only applies to USB Storage devices, and I think the total number of writes increasing only happens if the data to be written is changed constantly (e.g. writes that overlap on same region/block of a device) Most USB Storage devices are used for storing simple, consecutive streams of data, such as Music, Pictures and other simple files and are not usually modified much, thus, I think enabling sync makes sense in this regard. In my opinion, the benefits of mounting USB Storage devices with sync outweigh the detriments.

My proposal was exclusively for USB Storage devices, not internal ones, as I can understand the benefits of async outweighing the detriments in the case of internal/network etc storage devices. -- _______________________________________________ devel mailing list -- devel@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to devel-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/devel@xxxxxxxxxxxxxxxxxxxxxxx Do not reply to spam, report it: https://pagure.io/fedora-infrastructure/new_issue
