Product Overview

Expand your desktop or compatible laptop storage with the SANDISK 4TB Optimus GX PRO 850X PCIe 4.0 x4 M.2 2280 NVMe SSD. This solid state drive combines a generous 4TB capacity with an M.2 2280 form factor and an NVMe interface designed for compatible PCIe 4.0 x4 systems. It is suited to users who want substantial storage for games, applications, creative projects, and everyday files, while keeping the drive in a compact internal format.

The 850X model name and PCIe 4.0 x4 connection identify this as a drive intended for supported systems that provide the corresponding M.2 NVMe slot. Check your computer or motherboard documentation for M.2 2280 size, NVMe support, PCIe generation, and available drive capacity before purchase. Performance depends on the host system and configuration; no specific read or write speed is stated in the confirmed product details.

Key Features
