EXCLUZO NGFF B-Key SSD to Adapter DDR Memory Slot

Hi, If I order a t450s with the 16GB NGFF caching drive, the 3rd NGFF slot option, but no WWAN module, where will the 16GB ssd be installed?

Especially if you either have only one slot or no slots at all in your older desktop

twin slot The A93 meets Sony's requirements for use with the PlayStation 5, thanks in part to a compact heatsink that fits the expansion slot of the console It
