SKU IDENTIFICATION: WD_BLACK SN770M, 2 TB, part number WDS200T3X0G. Verify the complete label, hardware revision and firmware before installation.

Manufacturer-identified specifications

Product / exact MPNWD_BLACK SN770M 2 TB (WDS200T3X0G)
Capacity / form factor2 TB; M.2 2230.
Interface / host lanesPCIe 4.0 x4 NVMe. Published maxima require the compatible host generation and lane configuration; an older or lane-shared host can negotiate lower throughput.
ControllerNot specified in the WD product references cited.
NANDThe cited WD product references do not identify NAND type or supplier.
Sequential performanceUp to 5,150 MB/s sequential read and 4,850 MB/s sequential write. Vendor-rated figures apply under manufacturer test conditions, not as guaranteed sustained real-world results.
Endurance / warranty1,200 TBW; five-year limited warranty (manufacturer specifications).
Thermal packageThe cited WD references do not state an operating-temperature range. This compact 2230 module still needs the host’s approved thermal path; keep the handheld/laptop enclosure airflow unobstructed.

Firmware, host compatibility & thermal cautions

  • Check the WD product support/downloads page for model-matched firmware and diagnostics. Use the exact WDS200T3X0G model, not the 2280 SN770.
  • Designed for M.2 2230 NVMe slots. Confirm physical 30 mm standoff/retention, enclosure clearance, PCIe lane support and BIOS/UEFI boot compatibility; it will not fit a 2280-only retention layout without an approved adapter.
  • Check M.2 keying, slot length, single-/double-sided clearance, lane sharing, and system BIOS/UEFI support in the exact host manual; M.2 shape alone does not prove NVMe or boot compatibility.
  • Follow the drive and host maker’s heatsink and thermal-pad instructions. Keep airflow around the controller area, do not stack thermal materials or remove factory labels/cooling without explicit guidance, and expect sustained performance to vary with temperature and workload.
  • Shut down and remove standby power as instructed before installation; use ESD precautions. Back up data and retain recovery media and encryption keys before changing storage or updating firmware.
