RBU-SNS8100S31128GD

can you check this number as only place I can find it is here
How big was it? 128gb or 512gb? websites I find suggest the V17 Nitro had 512 but its serial code could mean its 128

this is a 512 model number - Rbu-sns8152s3/512gf
a 128gb code is Rbu - sns8100S3/128GH which is close

i wonder if your code isn't actually Rbu - sns8100S3/128gd - it exists, but all I can find is photos - link
Brand S.O.S

Sounds like you need to think about getting a new NVME, make it bigger too as they cheaper now.
