Several things have to be the case for 7.4 GB/sec SSD to outperform a 3.3 GB/sec SSD on real world tasks: Transfer speed depends heavily on transfer size Application behaviors

And since most apps use absurdly small buffers (1MB or smaller), they can never get full speed from the SSD. You need only glance at any of MPGвЂ™s test charts to see that transfer size matters hugely to speed. Next, a top speed of 7.4 GB/sec is *only* achieved for very large transfers. Once that cache is full, the overhead starts killing performance. How badly things are affected depends on the amount of memory 64GB will be worse than 32GB memory.

That 7.4 GB/sec quickly gets cut back by this bug, unless macOS Monterey has fixed it. What is required for 2X faster I/O to matterДЇor starters, macOS has a performance bug that cuts ultra-fast SSD speed in half for the very jobs that could most use the speed. The next closest thing next is a ~2.7 GB/sec Thunderbolt SSD, like the OWC Thunderblade or OWC Envoy Pro SX. To know for sure, youвЂ™d have to compare using a 3.3 GB/sec SSD, and there is no way to do that (no external can go that fast, and no other internal SSD is possible). Does it mean much of anything will run a lot faster? Nope-a little faster for some things, notably faster for a few things, and not much faster for most things. Does that mean your Photoshop files will save twice as fast? Nope.
