  • Our take on the WD_BLACK SN8100 4TB NVMe M.2 2280 PCIe Gen 5x4 Internal SSD

    The WD_BLACK SN8100 is a 4TB PCIe Gen 5 x4 NVMe drive in the M.2 2280 form factor, built for people who want top-tier sequential speed from a single slot. It is a flagship-class Gen 5 SSD aimed at gaming rigs, workstations and PS5 expansion, where its high throughput and large capacity stand out against Gen 4 drives and older Gen 5 models. Like most high-speed Gen 5 drives, it runs warm under sustained loads and benefits from a heatsink or good motherboard airflow.

    Questions and answers

    Is the WD_BLACK SN8100 worth it over a Gen 4 SSD?
    Only if your motherboard or PS5 can use Gen 5 bandwidth and you move large files or play big games. On a Gen 4 slot it will run at Gen 4 speeds, so a cheaper Gen 4 drive makes more sense.
    Does it need a heatsink?
    Under sustained Gen 5 loads it runs warm, so a heatsink or a motherboard M.2 shield is recommended. PS5 installation requires a heatsink that fits the console's expansion bay.
    Will it fit a laptop?
    It is a standard M.2 2280 drive, but Gen 5 laptops are rare and the drive's heat output can be a problem in tight chassis. Check that your laptop slot supports the length and has cooling.
    What is in the box?
    The drive itself, typically without a heatsink or mounting screws. You supply the heatsink and any screws your motherboard or console needs.
    How does it compare with the SN850X?
    The SN8100 uses PCIe Gen 5 for higher peak sequential speeds, while the SN850X is Gen 4. Real-world game load times are close; the SN8100's advantage shows in large sequential transfers on a Gen 5 platform.
    Where is the WD_BLACK SN8100 4TB NVMe M.2 2280 PCIe Gen 5x4 Internal SSD cheapest?
