Choose the correct 990 PRO 2TB configuration

The bare 2TB model is intended for systems that already provide an M.2 shield or low-profile cooling. The integrated-heatsink model suits compatible desktops and consoles with sufficient clearance. Both are M.2 2280 PCIe 4.0 x4 NVMe drives, but their physical height is different.

Confirm the model code, capacity, condition and seller before opening the package. Do not install a suspicious marketplace drive until the return evidence and labels are recorded.

• Match bare or heatsink to the system
• Verify the complete model code and 2TB capacity

Prepare backups, recovery keys and tools

Back up files that matter before working inside the system. An installation can expose unrelated problems such as a loose cable, incorrect boot order or accidental selection of the wrong disk during setup. Keep BitLocker or device-encryption recovery keys available.

Prepare the correct screwdriver, motherboard or laptop manual, mounting screw or tool-free latch, thermal pads and Windows installation or recovery media. Avoid magnetic clutter and work on a clean, static-safe surface.

• Keep an independent backup
• Prepare recovery media before changing the boot drive

Shut down and remove power safely

Use a full operating-system shutdown rather than sleep or hibernation. Disconnect AC power and external devices. For a desktop, switch off the power supply and discharge residual power as the case manual recommends. For a laptop, disable or disconnect the internal battery according to the service manual.

Use ESD precautions and handle the SSD by its edges. Do not touch the gold connector contacts or components. Never install or remove an M.2 module while the system is powered.

• Full shutdown is required
• Follow the device-specific battery procedure

Locate the correct M.2 socket

Use the exact motherboard or laptop documentation to identify a socket that supports M.2 2280 PCIe NVMe. Note whether the slot is CPU-connected, shares lanes, disables SATA ports or sits beneath the graphics card.

Remove the motherboard shield or laptop thermal plate carefully and keep each screw, pad and insulator in order. If the installed drive is being replaced, photograph its position and label before removal.

• Confirm NVMe and 2280 support
• Record lane-sharing and cooling hardware

Insert and secure the module

Align the M-key notch with the socket, insert the module at the angle shown in the manual and press it down gently to the mounting point. Secure it with the correct screw or latch without overtightening. The module should lie flat without bending.

If it resists insertion, stop and recheck the key and angle. Do not force the connector. A misplaced standoff can bow the board or leave the module loose.

• Never force the M-key connector
• Tighten only enough to secure the module

Install the thermal solution correctly

For the bare model, remove protective films from the motherboard or laptop thermal pad and reinstall the approved shield evenly. For the Samsung heatsink model, do not place a second motherboard cover on top unless the system maker explicitly supports that arrangement.

Check that pads contact the intended components and that no cable or plastic film is trapped underneath. Good thermal contact matters more than decorative mass.

• Remove thermal-pad films
• Use one correctly fitted heatsink system

Reassemble before powering on

Inspect the work area for forgotten screws, loose tools and displaced cables. Reinstall the graphics card or chassis cover without pressing against the SSD or heatsink. Reconnect the battery and power only after the module is secured and the system is complete.

For laptops, confirm the bottom cover closes without unusual pressure. For desktops, verify GPU fans and nearby cables can move freely.

• Do a visual inspection before power
• Never close a laptop against a forced heatsink

Confirm detection in BIOS or UEFI

Enter firmware setup on first boot and confirm the Samsung NVMe drive appears. If it does not, shut down and reseat it before changing partition settings. Also verify that storage mode, Secure Boot and boot order have not changed unexpectedly.

A new secondary SSD may appear in BIOS but not File Explorer until it is initialized and formatted. A cloned or existing drive should not be initialized merely because Windows does not assign it a letter.

• BIOS detection comes before Windows setup
• Do not initialize a drive that should contain data

Initialize a new blank secondary drive

In Windows Disk Management, identify the new disk by model and capacity. Bring it online if needed, initialize it with GPT for a modern UEFI system, create a New Simple Volume, assign a drive letter and format it with the desired file system.

Formatting destroys data on the selected volume. Double-check the disk number and approximate 1.82 TiB binary capacity before confirming. Do not perform this step on a cloned boot drive.

• Use GPT for modern Windows systems
• Verify the disk number before formatting

Set up a boot drive correctly

For a clean installation, boot the official Windows installer in UEFI mode, load any required VMD or RAID driver, select the 990 PRO and allow Setup to create the required partitions. Disconnect unnecessary drives when practical to prevent boot files from being placed elsewhere.

For a clone, complete the migration first, shut down, then boot from the new SSD. Keep the source unchanged until the destination has started reliably and important files are verified.

• Use UEFI mode for a modern GPT installation
• Retain the original drive until the clone is verified

Install Magician and check firmware

After Windows detects the SSD, install the current Samsung Magician release. Confirm the model, serial, firmware, health and negotiated interface. Compare firmware only with Samsung’s official tools page and back up before any update.

Magician may have limited functionality when the drive is behind RAID, VMD, SCSI or USB bridge paths. Do not change a boot controller mode merely to expose a management feature.

• Use the current official Magician version
• Do not change VMD or RAID casually

Validate temperature, capacity and performance

Allow Windows updates, indexing and any clone-related background work to settle before benchmarking. Confirm usable capacity, controller temperature and stability first. Then test with a suitable workload and compare the negotiated interface with the expected ceiling.

A Gen3 slot, two-lane link, chipset path or external enclosure will reduce headline throughput without making the SSD incompatible. Record the test conditions so the result can be interpreted correctly.

• Validate stability before maximum speed
• Compare results with the actual host link
