Consult with Lloyd on your computer or photographic purchase, backup strategy, archival and storage strategy, etc.
A big thank-you to B&H Photo for sending the $7999 Apple Mac Studio M1 Ultra 20-core CPU / 64-core GPU/ 128GB / 8TB SSD for review. This is exactly the configuration I would buy excepting a preference for a 4TB SSD (only to keep the cost down).
See the test notes for details on hardware configuration and software versions.
The Mac Studio M1 Ultra leaves the other computers in the dust for Export JPEG, with the 2019 Mac Pro 28-core taking 74% longer! OTOH, the 2019 Mac Pro 28-core is all but a match on Import showing just how task-dependent it can be.
