You are exploring sandisk wd black sn850x 2tb nvme SSD alternatives to match your specific gaming or workstation hardware. The original Sandisk WD_BLACK SN850X 2TB NVMe SSD delivers sequential read speeds up to 7,300 MB/s and write speeds up to 6,300 MB/s on the PCIe interface. It comes in a standard M.2 2280 form factor and includes an integrated heatsink for thermal cooling. This setup handles heavy continuous data transfers while keeping temperatures regulated in compatible desktop cases and gaming systems.

You might still need a different drive based on form factor limitations, controller specifications, or capacity targets. Laptops and slim enclosures often lack clearance for a pre-installed heatsink, requiring a bare M.2 card instead. Other motherboards support PCIe 5.0 interfaces capable of faster throughput, while some builds require a smaller 1TB storage footprint. We compiled these 6 alternatives because their core specifications overlap with the original drive across performance, form factor, and interface design.

Our top pick: WD_BLACK SN850X 2TB NVMe SSD with Heatsink.

Comparing SN850X Alternatives by Key Specs

WD_BLACK SN850 2TB Gen4 NVMe SSD

The WD_BLACK SN850 2TB provides sequential read speeds up to 7,000 MB/s and random performance reaching 1,000,000 IOPS using 3D NAND. Compared to the SN850X with heatsink, this drive drops read speed slightly from 7,300 MB/s and omits the pre-installed heatsink. Its slim 0.09-inch profile offers much greater installation clearance than the 1-inch height of the heatsink-equipped SN850X. You trade away dedicated passive cooling hardware and 300 MB/s of top-end read throughput. Choose this model if your motherboard already features integrated M.2 heatsinks or if your gaming chassis cannot accommodate the extra vertical clearance of the original heatsink version.

WD_BLACK SN770 2TB Gen4 NVMe SSD

The WD_BLACK SN770 2TB delivers sequential read speeds up to 5,150 MB/s alongside DirectStorage support for gaming setups. Against the SN850X, it trades away 2,150 MB/s in peak sequential read speed and does not include an attached thermal heatsink. In return, you receive a flat 0.09-inch thick card that slides under standard motherboard shields where bulky factory heatsinks will not clear. It matches the original drive in total 2TB capacity and standard M.2 2280 form factor. Choose the SN770 if your gaming rig does not require maximum sequential throughput and you need a compact drive that relies on existing motherboard cooling.

Sandisk WD_BLACK SN8100 2TB PCIe 5.0 SSD

The Sandisk WD_BLACK SN8100 2TB jumps to the PCIe 5.0 interface, delivering read speeds up to 14,900 MB/s with an integrated heatsink. This more than doubles the 7,300 MB/s read rate provided by the Gen4 SN850X. Both drives offer 2TB of capacity and built-in thermal cooling, but the SN8100 heatsink measures 0.44 inches tall, offering a more compact profile than the original 1-inch heatsink unit. However, unlocking this performance requires a motherboard with native PCIe 5.0 M.2 slot support. Pick the SN8100 if you operate an updated desktop platform ready for PCIe 5.0 bandwidth and need the fastest sequential throughput available.

Samsung 980 PRO 2TB PCIe 4.0 NVMe SSD

The Samsung 980 PRO 2TB delivers PCIe 4.0 performance with sequential read speeds up to 7,000 MB/s in a standard M.2 design. While the original SN850X tops out slightly higher at 7,300 MB/s read and incorporates a heatsink, the 980 PRO omits bulky thermal hardware. That missing heatsink makes it suitable for tight laptop bays and desktop M.2 slots covered by integrated motherboard heat spreaders. You give up the pre-fitted thermal block and 300 MB/s of sequential read capability. Select the 980 PRO if you require 2TB of dependable Gen4 storage for space-limited systems where factory heatsinks physically cannot fit.

Inland 2TB Gaming PCIe Gen4 NVMe SSD

The Inland 2TB Gaming SSD reaches sequential read speeds up to 7,100 MB/s and includes a 6-year warranty, exceeding standard coverage terms. It is specified for both PC and PS5 gaming systems. Compared to the SN850X, it trades away 200 MB/s of top-end read speed and ships without a pre-attached heatsink unit. That means you must supply an external heatsink or rely on your chassis cooling for high-demand sessions. You maintain identical 2TB capacity and high-tier Gen4 transfer rates. Pick this Inland drive if you are upgrading a PS5 or PC where you supply your own thermal cooling and prefer longer warranty protection.

WD_BLACK SN850X 1TB NVMe SSD with Heatsink

The WD_BLACK SN850X 1TB matches the original model's top sequential read speed of 7,300 MB/s and includes a factory-installed heatsink. Its primary difference is storage volume, offering 1TB instead of 2TB. However, this smaller capacity version features a lower-profile heatsink measuring 0.35 inches tall, compared to the 1-inch height on the 2TB edition. That slimmer profile provides easier clearance in tight desktop configurations without forfeiting passive thermal dissipation. You sacrifice half the total storage space for a more compact thermal footprint. Choose this 1TB option if you prioritize identical 7,300 MB/s read rates and heatsink cooling but have lighter overall capacity requirements.

Frequently asked questions

Which alternative should you choose if you need PCIe 5.0 speeds?

You should choose the Sandisk WD_BLACK SN8100 2TB PCIe 5.0 SSD if your motherboard supports Gen5 hardware. This drive delivers sequential read speeds up to 14,900 MB/s, doubling standard PCIe 4.0 bandwidth. It includes a dedicated integrated heatsink measuring 0.44 inches tall, making it suitable for desktop gaming configurations with adequate slot clearance.

Can you fit the Sandisk WD_BLACK SN850X heatsink model into tight laptop slots?

No, you cannot fit the heatsink-equipped SN850X into most tight laptop compartments. Its integrated cooling structure increases the physical dimensions beyond standard bare M.2 2280 slots. For compact laptops, the Samsung 980 PRO 2TB offers a slim standard M.2 design with 7,000 MB/s read performance that installs without heatsink clearance conflicts.

How does the WD_BLACK SN770 2TB compare to the SN850X for gaming?

The WD_BLACK SN770 2TB operates as a mainstream Gen4 alternative offering read speeds up to 5,150 MB/s. While slower than the 7,300 MB/s sequential transfer rates found on the SN850X, the SN770 includes DirectStorage support. It serves as an unshielded M.2 2280 drive for builds that do not require peak PCIe 4.0 sequential limits.

Which alternative works for PlayStation 5 storage expansion?

The Inland 2TB Gaming PCIe Gen4 NVMe SSD is specifically listed for PS5 and PC gaming compatibility. It delivers sequential read speeds reaching 7,100 MB/s over the NVMe interface. Because this model comes without an attached cooling block, you will need to add a compatible third-party thermal solution before inserting it into your console.

Is a 1TB version of the WD_BLACK SN850X available if 2TB is unnecessary?

Yes, the WD_BLACK SN850X 1TB NVMe SSD provides identical 7,300 MB/s read speeds in a smaller capacity. It retains the M.2 2280 form factor and includes a pre-installed heatsink for thermal management. This alternative fits desktop gaming systems when you want top-tier Gen4 sequential throughput but require less total storage capacity.

What differences exist between the WD_BLACK SN850 and SN850X?

The earlier WD_BLACK SN850 2TB reaches sequential read speeds up to 7,000 MB/s and random performance of 1,000,000 IOPS using 3D NAND. In comparison, the SN850X reaches 7,300 MB/s read speeds and 6,300 MB/s write speeds. The standard SN850 listed here also comes without a pre-installed heatsink, measuring just 0.09 inches thin.
