The new laptop has a total of 4 TB for host writes and 9 TB for host reads. Is this typical?
my new car has some kilometers driven, is this normal?
No.
Poor analogy new cars frequently have some miles on them. I get your point, but not in 30 hours. I worked for a huge automobile firm in Sweden and absolutely no new cars were delivered to client with 0km
edit: Since I am aware that the odometer may be reset, I have realized that things may differ in other nations.
Yes, but in most of my country (the US), it Is against the law to reset the odometer.
It is typical for new cars to have traveled fewer than 150 kilometers; often, this amounts to about 30 kilometers, and this is quite okay. Here, not a single dealership nor factory will reset.
Have you used it for thirty-one hours now?
Maybe they have cheated you the ssd they have given you yes genuinely old one it is not normal as new computers only few read and write Due to the installation of windows (15 GB minimum).
