the data storage alone is not the issue. the cost of accessing that data is. not every place has unlimited fast internet that would allow you to download that much data without problems.
with a replaceable SSD i can (and in fact just did a few weeks ago) take the SSD from the old laptop and put it into the new one. took me 5 minutes.
restoring all that data from the cloud would have cost me a few hundred dollars in mobile data fees. or several weeks of visiting a restaurant which has free data, but would also have racked up a restaurant bill not to mention the time that would have been taken away from working.
