There used to be only a few options for disk formats but if you’re working on Mac OS 10.13 or later there’s an additional one called APFS. That’s a somewhat universal format that is compatible between Macs and PCs and allows for the transfer of file larger that 4GB? which is important. But looking at it in the Disk Utility shows the formatting as ExFAT. When you buy a new external SSD and plug it into your Mac it usually mounts right up. This isn’t the first time I’ve thought about hard drives, drive speeds and SSDs in general. Often I’ll work in entire job off of an external SSD if I have to move it between systems at my home or office or a client facility. Since I’m a Mac user working in post-production I do a lot of file transfers and since external SSD drives have become quite affordable, are fast and easy to ship they have become a medium of choice when it comes to moving files around when an internet transfer isn’t feasible. I have often wondered if the different SSD drives formats really make a difference in speed.
