How to install WD Black SN770

• Power down your computer or laptop, unplug from any power source, and discharge any static electricity before handling components.
• Open the case or access panel to locate the motherboard’s M.2 slot. If you’re upgrading a laptop, consult the user manual for the exact access procedure and any required removal steps.
• Remove the screw securing the current M.2 drive or the slot’s mounting hardware, then gently insert the SN770 into the M.2 slot at a slight angle (about 30 degrees) until the connector is fully seated.
• Push the drive down to a horizontal position and secure it with the M.2 screw. Ensure the drive lies flat and does not protrude beyond the slot.
• Power on the system, enter the BIOS/UEFI to confirm the drive is detected, then boot into your operating system. Open your disk management tool to initialize, partition, and format the drive as needed for use as a data drive, game drive, or OS drive.

Frequently asked questions

• What is the WD Black SN770? The WD Black SN770 is a 1 TB NVMe PCIe Gen4 solid-state drive in the M.2 2280 form factor, designed to deliver fast load times, rapid data transfers, and robust gaming performance.
• What capacity options are available for this model? This listing is for a 1 TB version, which is part of the SN770 lineup that also includes higher capacities such as 2 TB for users who need even more space and sustained throughput.
• Is the SN770 compatible with PCIe Gen4 motherboards and laptops? Yes. The SN770 uses the PCIe Gen4 x4 interface and is designed to work with systems that support M.2 NVMe drives, including many modern desktops and laptops.
• Can I use the SN770 as my OS drive or do I need additional storage for games and data? The SN770 is suitable for use as an OS drive, a game library, or a fast data drive, depending on your setup and storage strategy. Properly initializing and formatting it within your OS will determine how you allocate space for system files and programs.
• Do I need a heatsink for the SN770? In many desktops, the included motherboard heatsinks and airflow are sufficient. In some laptops with limited airflow, a small heatsink or active cooling might help maintain peak performance during extended gaming sessions, but it is not a mandatory requirement for all systems.
• How do I ensure I’m getting the best performance from the SN770? Ensure the drive is connected to a PCIe Gen4 slot, enable NVMe in your BIOS/UEFI settings if required, and keep your system firmware and drivers up to date. Regular maintenance, such as keeping the system cool and avoiding excessive fragmentation, will help maintain high throughput and responsiveness.
