SanDisk SDPS31H-004T-GBCND Professional PRO-G40 4TB Portable SSD

Overview:

The SanDisk SDPS31H-004T-GBCND (SanDisk Professional PRO-G40) is a 4TB high-performance portable solid-state drive designed for professional data mobility, high-speed content workflows, and rugged field deployment environments. It is commonly used in production, enterprise backup, and engineering workflows where fast external storage and physical durability are required.

The drive supports dual-interface connectivity through Thunderbolt 3 and USB 3.2 Gen 2 Type-C, enabling flexible use across workstation-class systems and standard business laptops. When connected via Thunderbolt 3, it delivers transfer speeds up to 3000 MB/s read and 2500 MB/s write, while USB 3.2 Gen 2 connections support up to approximately 1050 MB/s read performance.

It is built with a PCIe NVMe internal architecture and a thermally optimized aluminum core designed to maintain sustained performance under heavy workloads. The enclosure is engineered for extreme durability, including resistance to dust and water ingress and high-impact conditions, making it suitable for field operations and mobile production environments.

The 4TB capacity supports large-scale workloads such as high-resolution video editing, raw image processing, virtual machine storage, and enterprise backup operations. It is typically used in workflows where fast external scratch disk performance is required.

In deployment, this drive is suitable for creative professionals, IT engineers, and enterprise users requiring portable high-speed storage with rugged environmental protection.

It is not intended as a replacement for internal enterprise storage arrays, nor for continuous 24/7 server-grade write-intensive workloads.

Typical Deployment Scenarios:

• High-resolution video editing and media production workflows
• Portable backup storage for enterprise and IT environments
• Field data capture and engineering site storage transfer
• External scratch disk for rendering and creative applications
• Secure data transport between isolated systems
