Yeah I know, but it's the same ballpark
But you said "as fast", not "almost as fast". Can't let those bits slip by without a challenge.
Yeah I know, but it's the same ballpark, first because these are not benchmark results, secondly because if you are running into a bottleneck at 1.25GB/s, getting 150MB/s more for $5.500 will probably not be enough to solve your problem. Regarding what sizes Apple will offer, I have no idea.
Nobody does, but still there are comments that the internal drive will be fine. And Apple could easily charge $6K for a TB drive.
Workstations are often set up with a minimal drive for the OS and a larger, faster drive for local data. Hard to see how the MMP will do that.
I'll praise Apple if they have a 2TB to 4TB internal drive option, or if the "blank space on the 2nd GPU where PCIe SATA drive should be" can get a BTO 2TB to 4TB data drive.
Of course, we'd need to be prepared for Apple to charge what most people would consider to be a hefty down payment on a house for those drives. That's the reality of proprietary form factor SSD drives (or at least "niche form factor", even if technically it's not proprietary).
