How long does NAS initial setup take?
Initial hardware setup (installing drives, connecting to the router) takes 15-30 minutes. The DSM operating system installation and initial configuration wizard takes another 20-30 minutes. Total first-time setup is typically under one hour. After setup, the NAS creates storage pools and volumes which may take additional time depending on drive size.
Do I need to format hard drives before putting them in a NAS?
The NAS operating system (DSM for Synology, QTS for QNAP) formats and partitions the drives during the initial setup process. Installing new, unformatted drives is the correct procedure. If you are reusing drives that have existing data, the setup will erase that data, back it up before installing.
