How to install Adata LEGEND 840

• Prepare your system: Power down your computer or console, unplug from power, and discharge any residual static. Gather a small precision screwdriver and the appropriate mounting screw for your M.2 slot if not already installed.
• Locate the M.2 slot: Open your PC or notebook’s service panel to access the M.2 slots. If you’re installing in a PS5 expansion bay, ensure you have a compatible heatsink and follow Sony’s documented installation guidelines for storage upgrades.
• Install the drive: Align the notch on the LEGEND 840 with the M.2 slot and insert at a slight angle (usually around 30 degrees). Once seated, gently press the drive flat against the motherboard and secure it with the mounting screw.
• Cool it when possible: If your system requires a separate heatsink, attach it according to the heatsink manufacturer’s instructions to help sustain maximum performance during heavy workloads.
• Power up and initialize: Boot your system. Enter the BIOS or UEFI to confirm recognition of the new drive. In Windows or macOS, initialize and format the drive as needed to begin using it for storage or scratch space.
• Update firmware and optimize: Use ADATA’s SSD Toolbox or the motherboard/system utility to check for firmware updates and enable features like TRIM and S.M.A.R.T. monitoring to optimize longevity and health reporting.

Frequently asked questions

• What speeds does the ADATA LEGEND 840 offer? The drive provides up to 5,000 MB/s sequential read and up to 4,500 MB/s sequential write speeds, enabling rapid data transfers, fast application launches, and smooth large-file workflows. Real-world speeds vary with system configuration, thermal conditions, and workload type, but the LEGEND 840 is designed to deliver flagship-like performance in a consumer-grade M.2 2280 SSD.
• Is the LEGEND 840 compatible with PS5? Yes, when installed in a compatible PS5 expansion bay with appropriate heat management. The M.2 2280 size fits many PS5 storage upgrade configurations, but a proper heatsink and cooling solution are recommended to maintain performance during long sessions and large-game installations.
• Do I need a heatsink for this drive? While not strictly required for all systems, a heatsink helps maintain cooler operating temperatures for sustained workloads on PCIe Gen4 NVMe drives. If you’re installing in a laptop, a built-in cooling solution is often sufficient; in desktops or PS5 expansions, a dedicated heatsink is advised to prevent thermal throttling during heavy use.
• What warranty does the LEGEND 840 include? The drive comes with a 5-year limited warranty, underscoring ADATA’s confidence in its reliability and long-term performance. The warranty typically covers defects in materials and workmanship under normal use, with terms outlined in the product documentation.
