Capacity and interface

The SanDisk Optimus GX PRO 850X is an 8TB internal SSD using the M.2 2280-D5-M form factor. It connects through a PCI-Express 4.0 x4 interface with NVMe 1.4 protocol. The drive targets gamers and creators who need high-capacity storage for large game libraries and creative projects.

Installation notes

The module measures 3.88mm in height, 22mm in width and 80mm in depth, weighing 8.6g. It ships without a heatsink, so motherboard-integrated cooling or an aftermarket spreader is recommended for sustained workloads. The single-sided M.2 2280-D5-M layout fits most desktop and laptop slots, but verify clearance around neighbouring components before fitting.

Compatibility checklist

Confirm your motherboard or laptop provides an M.2 slot keyed for PCIe 4.0 x4 NVMe operation. Check that the system BIOS supports NVMe 1.4 and that the operating system includes a compatible driver. Ensure the platform can supply up to 8.0W during write activity and that airflow keeps the drive within the 0°C to 85°C operating range.

Spurningar um þessa vöru

How can I confirm the drive is running at its rated 7200 MBps sequential read speed after installation?

Use the SanDisk Dashboard application on Windows to monitor real-time performance and run a benchmark that shows sequential read speeds approaching 7200 MBps over the PCIe 4.0 x4 link.

What accessories are included with the 8TB Optimus GX PRO 850X and what must I supply myself?

The package contains only the M.2 2280-D5-M SSD itself; you must provide a compatible motherboard M.2 slot, a mounting screw, and an aftermarket heatsink because the drive ships without one.

Which capacity should I choose if I need the highest endurance rating for heavy creative workloads?

The 8TB model delivers the maximum 4800 TBW endurance figure, making it the best choice for sustained write-intensive projects.
