That's the coloquialism from my side. I know proper term is soldered.
Take a look at this. Then take a look at some images from Mac Mini page. It definitely looks soldered. View attachment 799578
The NAND can be seen on some of the internal pictures released today. But the glue and solder issue is trivial compared to the fact that the NAND flash really is just that - it is not an SSD. To function as an SSD the raw NAND needs a controller and on the latest Macs that is provided by the T2.
Thanks
Still not 100% convinced though.
In the picture shown in your (StellarVixen)post it says
"Not User accessible" which to me means you can't really get to it easily.
You, RobbieTT have valid points, if the controller is on the T2 then I guess you must be right, but doesn't it also say it's PCIe which to me means a connector, or am I wrong?
