I sort of have a similar system inside my dell workstation. I have two SSDs internally for projects I am working on. Then I move all the files to my slower storage drives when I am finished with them.I remember reading about some testing comparing a single module vs two modules running on separate bus lanes. I don't remember all the details but seem to recall that the difference was enough to make me curious. And I agree, memory tests aren't real life.I'm aware that their was some discussion a couple of years ago than some particular model of Mac with 512GB ran memory tests faster than the same model with 256GB, and the conclusion that this was because it used two 256GB modules that ran on two bus lanes rather than one. As I recall, the difference wasn't huge. Also, memory tests aren't real life.
That said - I assumed that if there was a speed improvement using 2 buses vs 1 bus, perhaps some type of RAID was being used. I have no way of testing this assumption but did attach a couple of OWC Express 1M2 enclosures (each with a 4TB NVMe m.2 ssd drive) to my M2 Max Studio and ran the BlackMagic test in a variety of ways.
Test results:
M2 Max Studio w/2TB drive - just over 6000
OWC 1M2 w/4TB (single drive) - just under 3000
Two OWC 1M2 (4TB each) in RAID 0 (using 2 thunderbolt ports) - well over 5000 ... not far from the Studio's internal drive.
I do try to keep the Studio's disk capacity under 50%, keeping only apps & a few other things on the Studio with everything else on external drives. This has worked well for me. I generally process photos/videos on the Studio's drive but don't hesitate to use the OWC RAID 0 set since it really is quite fast.
Since the RAID 0 has no protection in the event of failure I have it mirrored to another set of drives (SSD SATA) that aren't as fast but are quick enough should the RAID 0 set fail. Everything is backed up on separate spinners as well as off-site Cloud backup. My setup is not perfect, nor, for my needs, need to be. In the event of a total non-recoverable failure of my RAID 0 set, the most I would lose would be approx. 10-20 minutes of the most recent work. As a non-professional that's a degree of risk I'm comfortable with.
FWIW - I used to maintain a trio of Synology NAS drives. Great for backups and file serving but the bandwidth pales in comparison to DAS, especially when the drives are NVMe in RAID 0.
If I get the mini M4 pro system, I will have a similar setup but using hidden externals. I am hoping that apple wakes up and put the same internals the m4 mini pro has in a 15 inch macbook air. PLEASE APPLE, I will move to you promptly if you give me the M4 pro chip and 64gb of ram in the air platform. I want lightweight for travelling.
