Welcome to the Dell Community [NAME]  As I have stated many times. Dell manuals are a "Good" reference for what was sold with the laptop. But, in no way do they reflect the limitations of the hardware. Best regards, U2
I own a Dell Inspiron 5567 Laptop (i5 7th Gen, 2TB HDD, 8Gb DDR4, 2Gb AMD Radeon R445). The HDD is too slow to use nowadays so I'm considering upgrading to a 1 TB SSD. I checked the manual & found that 256 Gigs of SSD is supported. Is this true?As I check on the "Crucial" site they showed up to 4 TB of SATA SSD is supported.So please clarify what does those capacity specs in the Owner manual actually means.  Regards.
