I have an M17xR4 with the Samsung: SSDR, 128, S3, FULL, MCARD, PM830.
I want to replace the SSD with the SanDisk Extreme PRO I wanted to be sure it is compatible. The SanDisk site doesn't really help and saw that Dell seems to respond to such questions in these forums.
My SSD is so low on space I need to do something fast.
