How to install WD Black SN850X

• Check compatibility: Ensure your motherboard or laptop provides an M.2 slot with PCIe NVMe support and a Gen4 capable interface. Confirm the slot length is 2280.
• Prepare tools and safety: Power down your computer, unplug it, and ground yourself to prevent static discharge. Gather a small Phillips screwdriver.
• Open your system: Remove the side panel on a desktop or access the drive bay on a laptop if applicable. Locate an available M.2 slot that supports PCIe NVMe.
• Install the drive: Align the notches on the SSD with the notch on the M.2 slot. Insert the SN850X at a slight angle (about 30 degrees) and press firmly until it lies flat. Secure the drive with the mounting screw provided by your motherboard or laptop chassis.
• Power up and initialize: Boot the system. In Windows, open Disk Management to initialize the new drive, format it if needed, and assign a drive letter. For macOS or Linux, use the appropriate disk utility to format the drive for your preferred file system.
• Enable cooling if necessary: If your build runs hot under load, consider adding the optional heatsink variant or ensuring adequate airflow to maintain peak performance during long gaming sessions or heavy workloads.
