Frequently Asked Questions

How big should the C drive partition be for Windows?

For Windows 11 with common software, allow 120GB to 150GB for the C drive. This leaves room for updates, temporary files and installed programs without slowing the system down.

Should I keep my data on a separate partition?

Yes. Keeping documents, photos and downloads on a separate D drive means you can reinstall Windows on C without losing your personal files, which makes servicing much safer.

Does partitioning improve my computer performance?

Partitioning mainly improves organisation and backup safety rather than raw speed. On an SSD the speed difference is negligible, but a clean data partition still makes maintenance and recovery easier.
