How to install Synology SAT5221-480G

Installing the SAT5221-480G is straightforward for most SATA-based systems. Follow these general steps to upgrade or populate your NAS or server with this drive:

• Power down the NAS or server and unplug it from the power source to prevent static discharge and data corruption.
• Open the drive bay or remove the existing 2.5" drive tray as required by your enclosure’s design.
• Align the SAT5221-480G with the SATA data and power connectors inside the drive bay. Ensure the connector pins are fully seated to prevent intermittent connectivity.
• Secure the drive into the tray or chassis with the appropriate screws or mounting hardware provided by your enclosure. Ensure the drive sits firmly to minimize vibration.
• Reinsert the drive tray or bay, reattach any cables, and power the system back on. Enter the NAS or server’s storage management interface to initialize or format the new drive according to your storage pool or RAID configuration.
