To calculate the average speed of 4 disk in a raid 0 is not multiplying the disk speed by 4, it is commonly said that you multiply by 1.5 for two. (I had raid 0 of 8 HD and a raid of 8 x SSD a long time ago)
You mislead me when you wrote "Studio Ultra TB4/USB4 front port vields a maximum read speed of 3,082MB/s and a maximum write speed of 2,853MB/s." what is it ?
Raid 0 is a good solution ! This configuration seems very promising
If you buy those components on Amazon, you can always send them back if your not happy of the results
I use "BlackMagic Disk test speed" to have the real speed
Understand that you have to have also a lot of memory and it is better to use VI instruments inside your DAW instead going to VE
I am very interested that you publish the result you get with "Blackmagic"
For the moment I am very happy using my MacBook Pro with 64 GB and 4TB internal MVMe, I can play very large orchestration (85 track) if I check that the swap is equal 0
