A speed comparison between https://en.wikipedia.org/wiki/Bcachefs, https://en.wikipedia.org/wiki/Btrfs, https://en.wikipedia.org/wiki/Ext4, https://en.wikipedia.org/wiki/F2FS, and https://en.wikipedia.org/wiki/XFS on Linux. These are all file systems, like windows ntfs https://en.wikipedia.org/wiki/NTFS or the apple journalling file system https://en.wikipedia.org/wiki/Apple_File_System.
While usually unimportant for most use-cases, and with each offering differing features and capabilities, in data-heavy systems speed can be an important factor in determining whether to use one file system over another.
It’s also ‘my car can beat your car in a drag race’ for geeks, because again it usually doesn’t matter and features are far more important than speed for the typical user.
