My assumption is that these speed slowdowns also apply to NVMe SSDs, but I don’t have the hardware to test this currently. While these speed slow-downs won’t generally affect single camera editing, they can dramatically impact multicam edits and DIT transfers. Ventura 13.1 reads 25% slower than Monterey.Ventura 13.1 writes 14.7% slower than Monterey.When a PCIe SSD is formatted using APFS (the current Apple file system): Also, once a drive is formatted as APFS, the process of re-formatting a drive into ExFAT changed.Ventura 13.1 reads 35% slower than in Monterey!.Ventura 13.1 writes 25% slower than Monterey.When a PCIe SSD is formatted using ExFAT:

So, I decided to test this to see if it’s true. In it they warned that macOS Ventura reads and writes ExFAT drives significantly more slowly than macOS Monterey. Just before I started my webinar last Wednesday, I read a warning on the blog about ExFAT.
