  • Our take on the 4TB NVMe M.2

    This is a 4TB M.2 2280 solid-state drive using PCIe 4.0 x4 and 3D TLC NAND, built on the Phison E21 controller. It is a DRAM-less design rated up to 4,100 MB/s sequential read and 4,800 MB/s sequential write, with 1,000,000 IOPS random read and write and a 4.0 PBW endurance rating. It suits people who want a large, fast game or media drive in a single slot, and it runs without a heatsink, so a motherboard or aftermarket cooler is needed under sustained load. Against premium PCIe 4.0 drives it trades peak speed and DRAM caching for capacity, and its write rating outpaces its read rating, which is unusual for this class.

    About the 4TB NVMe M.2

    This is a 4TB NVMe solid-state drive in the M.2 2280 form factor. It uses 3D TLC memory and a Phison E21 controller, and it connects over a PCIe 4.0 x4 NVMe interface.

    It reads at up to 4100 MBps and writes at up to 4800 MBps sequentially. Random 4KB reads and writes reach up to 1,000,000 IOPS. The drive does not include a heatsink.

    Questions and answers

    Is this drive fast enough for gaming?
    Yes. PCIe 4.0 with up to 4,100 MB/s read and 1,000,000 IOPS random read loads games quickly. It is not the fastest PCIe 4.0 drive, but the gap shows mainly in large file transfers.
    Do I need a heatsink?
    The drive ships without one. Under light use it runs fine bare, but for sustained writes or a cramped laptop, use your motherboard's M.2 heatsink or a slim aftermarket one.
    What is the difference between TLC and QLC here?
    This drive uses 3D TLC NAND, which generally holds write speed better than QLC once the cache fills. That matters for large transfers and long recording sessions.
    What does 4.0 PBW mean?
    It is the rated total bytes you can write over the drive's life: 4,000 terabytes. For typical desktop use that is far more than most owners will write.
    Will it fit my laptop or desktop?
    It is M.2 2280, the common 80 mm length, and needs an M.2 slot with PCIe 4.0 or 3.0 support. In a PCIe 3.0 slot it works but runs at PCIe 3.0 speeds.
    Why is the write speed higher than the read speed?
    The rated sequential write of 4,800 MB/s exceeds the 4,100 MB/s read. That is the manufacturer's specification; real-world results depend on your slot, cooling and workload.
    Where is the 4TB NVMe M.2 cheapest?
    At Build Redux, for $364.00, as of our latest check.
