pnpm is as fast and sometimes even faster than npm and Yarn (see benchmarks)
One version of a package is saved only ever once on a disk. So you save dozens of gigabytes of disk space!
pnpm creates a non-flat
node_modules, so code has no access to arbitrary packages
pnpm uses hard links and symlinks to save one version of a module only ever once on a disk. When using npm or Yarn for example, if you have 100 projects using the same version of lodash, you will have 100 copies of lodash on disk. With pnpm, lodash will be saved in a single place on the disk and a hard link will put it into the
node_modules where it should be installed.
As a result, you save gigabytes of space on your disk and you have a lot faster installations! If you'd like more details about the unique
node_modules structure that pnpm creates and why it works fine with the Node.js ecosystem, read this small article: Flat node_modules is not the only way.

What developers are saying
Shoutout to the people behind pnpm; it makes looking at node module source code so much easier because I don't have to sift through the hundreds of modules everything pulls in to find the one I want <3— 🏳️🌈👩💻 Opal Symes (she/her) (@software_opal) August 26, 2018
pnpm is gr8 tbh and 💚 the devs. Have you given it a whirl yet? https://t.co/WB9IkkElAB— actually a kat girl (@maybekatz) August 21, 2018
