Are you sure the contraption doesn’t have some limits? I was looking at these for backup options. I thought they had some.

these devices have no circuits. they are simply (electro-)physical adapters.
am i sure? no, i don't think i'd go quite that far.
we might get some better feel if i can get some benchmark numbers using my pci-to-cfe-b adapter card.
but all my results are consistent. ALL the high end cards, including the lexar diamond which i measured at 1666.42MB/s and that should pretty comfortably support 20fps lossless.

i spent many, many hours trying to get my four sabrent rocket 4.0 2230 drives to the current fw level.
i had four of these drives, 2 x 512GB, 2 x 1TB, and i managed to get only half of them updated. in all cases they were all one rev behind in fw.
i will say that my pc does not like those particular drives connected in any way other than usb (which isn't a method i can use to flash).
my system won't boot with those connected via pci to m.2 adapter, nor via pci to cfe-b adapter, nor in a motherboard m.2 slot.
for a while there i started to think it was just my system, but i confirmed that i could use a different m.2 module in the pci to m.2 adapter in any of the pci slots.
i don't know if these drives are "bad" or what. they work when used via usb and in the camera, but this inability to work in this way and my inability to get their fw up to date makes me trust them less and highlights a risk with the diy approach. i think this will all be better on thunderbolt systems since i understand we can flash thunderbolt connected devices, and there are lots of thunderbolt enclosures, and now even thunderbolt cfe-b readers that we can use

one thing i picked up is while cfe is “just” nvme, it does have a lower power threshold, which implies not all modules may work

i’ve decided to do one last performance related test. there are some intel optane m.2 modules on fire sale and they have incredibly low latency. i’ve ordered on of these and will try it in the m.2 to cfe adapter in-camera
i actually have a little expectation that if these run at all that it’ll run somewhat faster in camera than anything we’ve seen before since while i think the camera is the bottleneck, these should reduce the time the camera is waiting between operations

optane in-camera test is a bust. green light goes on and never goes off. GUESSING it doesn't get enough power. works in a card reader in the same rig.
suggestions welcome, but seems like it's a bust

What is the reason at half full the card choked? Are Delkin cards double in size for that matter?
I have a feeling Nikon throttles the buffer to control the heat buildup.
