So I got an interesting response from Sonnet!
I do not know what to make of all this craziness. I very much appreciate the Sonnet folks at lest being aware of some of these issues. But considering we have reports, above, that the 61TB Solidigm drive "seems" to work at full write speeds, I'm even more baffled as to what it all means.
What I don't get about the above statement is that it is clearly not true with regard to capacity as 20+TB spinning drives work just fine in macOS. So not sure why there is a capacity limitation for SSDs?
Would appreciate anyone with any thoughts on any of this. I'm prepping to send the 30tb intel drive back, and was going to look for a 61tb Solidigm, but now wondering if I should bother... but with a hearsay report of the 61TB drive working, perhaps that's all we got to go on? Man, I cannot believe the dearth of information about such a simple thing. So weird.
