SanDisk Optimus GX PRO 850X 1TB SSD

The SanDisk Optimus GX PRO 850X is a 1TB internal SSD built for gaming PCs and creator workstations. It uses the M.2 2280 form factor with a PCIe 4.0 x4 interface and NVMe 1.4 protocol. 3D NAND TLC memory provides the storage foundation for demanding workloads.

PCIe 4.0 x4 sequential performance

This drive delivers maximum sequential read speeds of 7300 MBps and maximum sequential write speeds of 6300 MBps. Random read reaches 800000 IOPS while random write hits 1100000 IOPS. These figures decide if the drive matches your throughput requirements.

Thermals and power in normal use

The SSD operates between 0°C and 85°C without a heatsink. Average active power draw is 7.2W during reads and 6.2W during writes. Idle consumption sits at 5 mW. Endurance is rated at 600 TBW with an MTBF of 1750000 hours.

Questions about this item

What does the 7300 MBps sequential read mean once the drive is installed?

The 7300 MBps figure is the peak PCIe 4.0 x4 throughput for large-file transfers such as game loads or video scrubbing; real-world speeds depend on system cooling, workload and firmware.

How does the PCIe 4.0 x4 NVMe 1.4 interface limit performance?

The four-lane Gen 4 link caps sequential throughput at the drive's rated 7300 MBps read and 6300 MBps write; older PCIe 3.0 slots will halve that ceiling.

Will the M.2 2280-S3-M module fit my laptop or desktop slot?

The single-sided 2280 form factor fits standard M.2 key-M slots in laptops and desktops; no heatsink is included, so verify clearance if your board has a tight cover.
