8TB NVMe SSD for gaming and creative PCs

The SanDisk Optimus GX PRO 850X is an 8TB internal solid-state drive built for high-performance gaming rigs and content-creation workstations. It uses 3D NAND TLC flash and the NVMe 1.4 protocol over a PCI-Express 4.0 x4 interface. Sequential reads reach 7200 MBps and writes hit 6600 MBps, while random 4KB performance scales to 1200000 IOPS for both read and write workloads.

M.2 2280 form factor with integrated heatsink

The drive fits a standard M.2 2280-D5-M slot on desktop motherboards and compatible laptops. An integrated Optimus heatsink with programmable RGB LED is pre-attached, so no separate cooling bracket is required and motherboard M.2 shields can stay in place. TCG Opal v2.01 hardware encryption secures data at rest without software overhead, and the SanDisk Dashboard utility for Windows adds drive-health monitoring and a Game Mode toggle.

Thermal throttle resistance and power profile

The heatsink helps the controller sustain peak throughput during extended loads, keeping the drive inside its 0°C to 85°C operating window. Idle power draw is just 5 mW, while average active consumption measures 6.7W during reads and 8.0W during writes. The 4800 TBW endurance rating and 1750000-hour MTBF reflect the 3D NAND TLC architecture’s durability for heavy daily workloads.

Questions about this item

Will this M.2 2280 drive with its included heatsink fit inside a typical laptop expansion slot?

The drive uses the M.2 2280-D5-M form factor and ships with the SanDisk Optimus heatsink attached. The heatsink adds height, so verify your laptop's M.2 slot clearance before installing. Many thin-and-light laptops only accept single-sided modules without a heatsink.

My motherboard only has PCIe 3.0 M.2 slots. Can I still use this NVMe 1.4 SSD and what performance should I expect?

Yes, the SSD is backward compatible with PCIe 3.0 x4 slots. It will operate at the slot's maximum throughput, so sequential speeds will be limited to roughly 3 500 MBps read and 3 000 MBps write instead of the rated 7 200/6 600 MBps. Random IOPS remain high for responsive everyday use.

Does the 8 TB model support hardware encryption and management software on Windows and Linux?

The drive features TCG Opal v2.01 data-at-rest encryption for hardware-based security. SanDisk Dashboard software for monitoring, firmware updates and Game Mode is Windows only. On Linux you can manage encryption with tools such as sedutil or nvme-cli, but the vendor utility is not available.
