Data thruput limit for Dual NVME RAID ?

[mjoshi123]

Are there any good dual NVME RAID solutions that have RAID 0 data thruput of more than what single NVME SSD will allow ? I'm looking to pickup 2 2TB 980 pro of Samsung they have read write speed of 5000 MBPs so I'm thinking if I do RAID 0 for this two SSD and use it with my Mac Stuodio M1 MAX thru thunderbolt it should be perfect solution for LR and Photoshop work I do currently. Or are there better alternatives ?

None will be faster as that SSD maxes out Thunderbolt interface by itself. I expect the most you can hope for is improved sequential writing of very large files.

Can you do raid 0 over two thunderbolt ports? If so you could use two enclosures that you could merge as one and probably get 5000 mbps combined?

This thread has a lot of discussion on NVME, RAID, TB ports, etc. Results depend on which ports you select, the enclosure (some perform better than others) and the drive... there are faster drives.

What external storage solutions are you going to use with the Mac Studio

There are several that use two enclosures and RAID them to provide high performance.

For Macs with Integrated Thunderbolt (such as Apple Silicon Macs or MacBook Pro (13-inch, 2020, Four Thunderbolt 3 ports)), it shouldn't matter which two Thunderbolt ports you use to do RAID 0.

Buried in those referenced threads is an explanation and results that suggest spreading the drives across controllers is better. The Studio which has at least two TB controllers. There is also the effect of where you connect the display. Dunno the detail offhand.

On probably wouldn't notice the difference in typical everyday use, however.

Apple Silicon Macs have a separate Thunderbolt controller for each integrated Thunderbolt port.

The MacBook Pro (13-inch, 2020, Four Thunderbolt 3 ports) uses an Ice Lake CPU which also has integrated Thunderbolt port. There's one controller for each side of the MacBook Pro (two ports for each). The Thunderbolt controllers can do more than the PCIe gen 3 x4 bandwidth of discrete Thunderbolt controllers.
