2TB PCIe 4.0 NVMe drive

The SanDisk Optimus GX PRO 850X is an M.2 2280-S3-M internal SSD with 2TB capacity. It uses PCI-Express 4.0 x4 and NVMe 1.4 to reach sequential read speeds up to 7300 MBps and sequential write speeds up to 6600 MBps. The drive employs 3D NAND TLC and is rated for 1200TB written endurance.

Gamers and creators needing speed without a heatsink

This model suits gaming PCs, creator workstations and laptops that can cool an M.2 drive through the motherboard or chassis. It supports Microsoft DirectStorage and TCG Opal v2.01 encryption for protected data at rest. Builds that rely on a drive-mounted heatsink or that cannot dissipate up to 7.5W active power should consider a different SKU.

Check motherboard slot, cooling and OS

Verify the board provides an M.2 2280 slot wired for PCIe 4.0 x4 and NVMe 1.4. Confirm the platform can keep the drive within the 0°C to 85°C operating range without an integrated heatsink. The SanDisk Dashboard utility for drive health and Game Mode runs on Windows only.

Perguntas sobre este artigo

What motherboard slot does the M.2 2280 form factor require?

The drive fits an M.2 2280-S3-M slot keyed for PCIe 4.0 x4 NVMe 1.4 operation.

Will the PCIe 4.0 x4 interface run at full speed on a PCIe 3.0 motherboard?

The SSD is backward compatible and will operate at PCIe 3.0 x4 speeds on an older platform.

How can I confirm the sequential read speed reaches 7300 MBps after installation?

Run a benchmark such as CrystalDiskMark on Windows; the sequential read result should approach 7300 MBps.
