2. Configuració i instal·lació

Before beginning the installation, ensure your computer is powered off and disconnected from the power source. It is recommended to wear an anti-static wrist strap to prevent electrostatic discharge (ESD) damage to the SSD and other components.

2.1. Physical Installation (Laptop)

1. Locate the hard drive bay on your laptop. This often involves removing a panel on the bottom of the laptop. Refer to your laptop's service manual for specific instructions.
2. If replacing an existing drive, carefully remove the old drive from its bay. You may need to detach a bracket or connector.
3. Attach any necessary mounting brackets or adapters from your old drive to the new Samsung PM851 SSD.
4. Slide the Samsung PM851 SSD into the drive bay, ensuring the SATA data and power connectors align correctly.
5. Secure the SSD with screws if required by your laptop's design.
6. Reattach the laptop panel and reconnect the power source.

2.2. Physical Installation (Desktop)

1. Open your desktop computer case.
2. Locate an available 2.5-inch drive bay. If only 3.5-inch bays are available, you will need a 2.5-inch to 3.5-inch adapter bracket (sold separately).
3. Mount the SSD into the drive bay or adapter bracket.
4. Connect a SATA data cable from the SSD to an available SATA port on your motherboard.
5. Connect a SATA power cable from your power supply unit (PSU) to the SSD.

2.3. Initializing and Formatting the SSD

After physical installation, the SSD needs to be initialized and formatted before use.

1. Enceneu l'ordinador.
2. Per a Windows: Right-click on the Start button, select "Disk Management." The new SSD should appear as "Unallocated Space." Right-click on the unallocated space, select "Initialize Disk," choose GPT (GUID Partition Table) for modern systems or MBR (Master Boot Record) for older systems, then create a "New Simple Volume" and follow the wizard to format it (NTFS recommended).
3. Per a macOS: Open "Disk Utility" (Applications > Utilities). Select the new SSD from the sidebar, click "Erase," choose a name, format (APFS or Mac OS Extended (Journaled)), and scheme (GUID Partition Map), then click "Erase."
4. Per a Linux: Utilitzeu eines com ara GParted o fdisk/mkfs per particionar i formatar el disc.

3. Funcionament i ús

The Samsung PM851 SSD operates as a standard storage device. Once installed and formatted, it can be used for operating system installation, application storage, and data files.

• Unitat del sistema operatiu: Installing your operating system on the SSD will significantly improve boot times and overall system responsiveness.
• Emmagatzematge de dades: Store frequently accessed applications and files on the SSD for faster loading and access times.
• Suport de TRIM: Ensure your operating system has TRIM enabled. TRIM helps maintain the performance and longevity of the SSD by allowing the operating system to inform the SSD which data blocks are no longer in use and can be wiped internally. Modern operating systems (Windows 7+, macOS 10.6.8+, Linux kernel 2.6.33+) typically enable TRIM automatically for SSDs.

4. Manteniment i bones pràctiques

Proper maintenance can extend the lifespan and maintain the performance of your Samsung PM851 SSD.

• Evitar la desfragmentació: Unlike HDDs, SSDs do not benefit from defragmentation. It can actually reduce the lifespan of the drive by increasing unnecessary write cycles. Ensure your operating system's defragmentation utility is disabled for the SSD.
• Actualitzacions de firmware: Periodically check the Samsung website for firmware updates for the PM851 series. Firmware updates can improve performance, stability, and compatibility. Follow Samsung's instructions carefully when performing firmware updates.
• Sobreprovisionament: While not user-configurable on this model, modern SSDs often reserve a small percentage of their total capacity for internal management tasks. Avoid filling the drive to 100% capacity to allow the SSD's garbage collection and wear-leveling algorithms to function optimally.
• Còpia de seguretat de dades: Regularly back up important data to another storage device. While SSDs are generally reliable, no storage device is immune to failure.

5. Solució De Problemes

If you encounter issues with your Samsung PM851 SSD, refer to the following common troubleshooting steps.

5.1. El sistema no detecta l'SSD

• Comproveu les connexions: Ensure the SATA data and power cables are securely connected to both the SSD and the motherboard/PSU.
• Configuració de la BIOS/UEFI: Enter your computer's BIOS/UEFI settings during startup. Verify that the SATA port the SSD is connected to is enabled and that the SATA mode is set to AHCI (Advanced Host Controller Interface) for optimal SSD performance.
• Prova un altre port/cable: Test the SSD with a different SATA data cable, power cable, or motherboard SATA port to rule out faulty components.
• Inicialitzar el disc: If detected in BIOS/UEFI but not in the operating system, ensure the drive has been initialized and formatted as described in Section 2.3.

5.2. Rendiment lent

• Mode AHCI: Confirm that your SATA controller is operating in AHCI mode in your BIOS/UEFI settings.
• TRIM habilitat: Verify that TRIM is enabled for your operating system.
• SATA III Port: Ensure the SSD is connected to a SATA III (6.0 Gb/s) port on your motherboard for maximum speed. Connecting to a SATA II (3.0 Gb/s) port will limit performance.
• Actualitzacions de controladors: Assegureu-vos que els controladors SATA de la placa base estiguin actualitzats.
• SSD Health: Use a utility like Samsung Magician (if available for this model) or other third-party tools to check the SSD's health and SMART status.
