An upgrade may help with:
More room for files, apps and games
High potential benefitEveryday responsiveness when replacing a slower or older drive
Workload-dependent
Best reason to upgrade
More storage headroom, plus faster everyday performance if replacing a slower drive.
May not help much if: If your current drive is already a fast NVMe SSD, replacing it with another modern NVMe SSD is unlikely to produce a noticeable everyday speed difference — capacity is the main benefit in that case.
