3. Setup and Installation
Before beginning installation, ensure your system is compatible with an NVMe M.2 SSD. This typically requires a motherboard with an M.2 slot supporting PCIe NVMe. Refer to your motherboard's manual for specific compatibility details.
3.1 Physical Installation
- Power Off and Ground: Turn off your computer and disconnect it from the power source. Ground yourself to prevent electrostatic discharge.
- Locate M.2 Slot: Identify the M.2 slot on your motherboard. If using an adapter card, insert the Samsung 950 PRO SSD into the adapter card first.
- Insert SSD: Gently insert the Samsung 950 PRO SSD into the M.2 slot at a slight angle. Press down on the SSD until it is level and secure it with the provided screw (if applicable, typically with the motherboard or adapter).

3.2 BIOS Configuration
After physical installation, you may need to adjust BIOS settings. Restart your computer and enter the BIOS/UEFI setup (usually by pressing Del, F2, or F10 during boot-up).
- PCIe Slot Configuration: Ensure the PCIe slot used for the M.2 SSD (or adapter) is configured correctly (e.g., x4 mode if applicable).
- Boot Mode: For NVMe SSDs, it is generally recommended to use UEFI boot mode. You may need to disable CSM (Compatibility Support Module) and set Secure Boot to "Other OS" or similar, then clear Secure Boot keys.
- Verify Detection: Confirm that the BIOS detects the Samsung M.2 drive.
- Save and Exit: Save your BIOS settings and exit.
3.3 Operating System Installation/Migration
For optimal performance, it is recommended to install your operating system directly onto the 950 PRO SSD. If migrating an existing OS, use Samsung's official migration software or a reputable third-party tool.
- Format SSD: In Windows, open Disk Management (Control Panel > System and Security > Administrative Tools > Computer Management > Disk Management). Initialize the SSD as GPT and format it with NTFS. Create a single partition.
- Install NVMe Driver: Download and install the latest Samsung NVMe driver from the official Samsung website (www.samsung.com/ssd). Verify its installation in Device Manager under "Storage Controllers."
- OS Installation: If performing a fresh OS install, boot from your OS installation media (e.g., USB drive) and select the Samsung 950 PRO as the installation target.
- Boot Order: After OS installation, ensure your BIOS boot order prioritizes the Samsung 950 PRO SSD.
4. Operating Instructions
Once installed, your Samsung 950 PRO SSD will function as a primary storage device. For optimal performance and management, utilize the Samsung Magician software.
4.1 Samsung Magician Software
Samsung Magician is a utility designed to help users manage and optimize their Samsung SSDs. It provides features such as:
- Performance Benchmark: Measure the read/write speeds of your SSD.
