Can I store Kaspa node data on a separate or slower hard drive in Windows?

Yes — Kaspa's node software (kaspad) lets you choose any folder on any drive for its data, and it does not require a fast SSD. To point kaspad at a different location, add the --appdir flag (or its shorthand -b) to your startup command, followed by the folder path. For example, to store data in C:\kaspa_data you would run: kaspad.exe --appdir c:\kaspa_data --utxoindex. This matters for Windows users with a small system drive, because Kaspa node data can grow large over time — moving it to a spacious secondary HDD keeps your main drive free without hurting node performance.
