A little perspective
About 1.95 times the data of 512 GB drive.
512 GB drive: Laptop storage is the internal memory where a laptop saves its files, applications and operating system data.
Measurements, assumptions & sources +
1 TB drive
One trillion advertised bytes: approximately 931 GiB. This is not a loss of physical storage.
Defined examples — our methodology
The marked data is calibrated. Unmeasured illustration details are representative.
512 GB drive
512 billion bytes of advertised decimal capacity. Binary displays report a smaller numerical GiB count.
