Product information

Description

The SanDisk Optimus GX PRO 850X 4 TB M.2 PCI Express 4.0 NVMe TLC 3D NAND Solid State Drive is a high-performance storage solution engineered for modern desktop computers and laptops. Delivering exceptional read speeds up to 7300 MB/s and write speeds up to 6600 MB/s, this solid state drive significantly reduces application loading times and accelerates data transfers. Utilizing advanced TLC 3D NAND technology and a PCI Express 4.0 interface, it provides reliable, high-capacity storage for demanding users who require fast and secure data management.

Advantages

This solid state drive offers remarkable data transfer speeds that enhance overall system responsiveness, making heavy file transfers and rapid application launches effortless. The generous 4 TB storage capacity provides ample room for extensive digital libraries, large games, and complex multimedia projects without the constant need for file deletion. Hardware-based encryption safeguards sensitive files and projects, ensuring robust data security at rest. The efficient M.2 form factor integrates seamlessly into compatible motherboards without requiring messy cables.

Suitable for

  • High-performance gaming personal computers and laptops
  • Professional video editing and content creation workstations
  • Heavy multitasking and rapid data-intensive workflows
  • Users requiring secure hardware-encrypted storage

When it may not be suitable

This solid state drive is not compatible with older motherboards lacking an M.2 slot or PCI Express 4.0 support, as it requires a modern interface to achieve its maximum performance capabilities. It may also exceed the storage and speed requirements of basic office computers used strictly for web browsing and light document processing.

Key specifications

  • 4 TB storage capacity
  • M.2 form factor
  • PCI Express 4.0 interface
  • NVMe technology
  • TLC 3D NAND memory type
  • Hardware encryption support
  • Designed for PC and laptop use

How to use

Install the solid state drive directly into an available and compatible M.2 slot on your computer motherboard, securing it with the designated screw or retention mechanism. Ensure your operating system and motherboard BIOS are fully updated to recognize the drive correctly. Once installed, initialize and format the drive through your operating system disk management utility to begin storing files, installing applications, or migrating your operating system.

What to consider before purchase

  • Verify that your motherboard features an M.2 slot with PCI Express 4.0 support
  • Check available physical space inside your computer chassis for proper installation
  • Confirm whether your system requires hardware encryption features for data security
  • Assess your storage needs to ensure 4 TB capacity aligns with your usage
Usage recommendations: Handle the solid state drive by its edges to avoid touching the gold connector pins and prevent electrostatic discharge. Ensure adequate airflow or use a compatible heatsink within your system to maintain optimal operating temperatures during sustained heavy workloads.
