There are quite a few utilities:
sudo apt install ncdu ncdu
It’s much faster than ncdu especially for SSDs. It scanned a 1TB SSD in 7 seconds.
curl -L https://github.com/dundee/gdu/releases/latest/download/gdu_linux_amd64.tgz | tar xz chmod +x gdu_linux_amd64 sudo mv gdu_linux_amd64 /usr/bin/gdu gdu
3. dua – Disk Usage analyzer
This also claims to be fast for SSDs. It starts the interface even before sundirectories are scanned, so that makes it even faster than gdu
curl -LSfs https://raw.githubusercontent.com/byron/dua-cli/master/ci/install.sh | sh -s -- --git byron/dua-cli --target x86_64-unknown-linux-musl --crate dua sudo ln -s ~/.cargo/bin/dua /usr/bin/dua dua
