  • Our take on the M.2 2280 NVMe SSD 1TB PCIe Gen 4 GM988

    The GM988 is a PCIe Gen 4×4 M.2 2280 NVMe drive using 3D NAND, rated up to 7350 MB/s sequential read and 6600 MB/s sequential write. The 1TB model carries a 512 TBW endurance rating and a 3-year warranty, which is shorter coverage than the 5-year terms common on drives from Samsung, WD and Crucial. It suits builders and upgraders who want fast Gen 4 speed for a desktop or a compatible laptop slot and accept a shorter warranty. Buyers should check that their board or laptop supports PCIe 4.0 to get the rated speeds; on a Gen 3 slot it runs at Gen 3 pace.

    • 5 / 51,032 ratings

    Ratings for this drive are very high, with buyers mainly reporting easy installation and fast boot and load times.

    What people mention
    • SpeedPraisedBuyers report quick boots and fast file transfers that match the Gen 4 ratings on compatible hardware.
    • SetupPraisedOwners say the drive installs easily in a standard M.2 2280 slot and is recognized right away.
    • WarrantyCriticisedSome buyers note the 3-year coverage is shorter than the 5 years offered by major rivals.
    • Sustained writeMixedLong transfers can slow below the peak sequential write figure once the cache fills.

    About the M.2 2280 NVMe SSD 1TB PCIe Gen 4 GM988

    This is a 1TB M.2 2280 NVMe SSD with a PCIe Gen 4×4 interface and 3D NAND flash. It uses HMB+ Dynamic SLC Cache and a graphene copper cooling design to help keep temperatures down and performance steady under load.

    It works with Windows and Linux systems and fits laptops, desktops and the PlayStation 5, and is also listed as compatible with Xbox Series consoles. It is plug and play. Maximum speed is reached only through a PCIe 4.0 connection, and USB external enclosures often limit speed.

    Questions and answers

    Will this work in a PCIe 3.0 slot?
    Yes, it is backward compatible, but it will run at PCIe 3.0 speeds rather than the rated Gen 4 figures.
    Does it fit a laptop?
    It is a standard M.2 2280 drive at 2.1mm thick, so it fits laptops with a full-length 2280 slot. Check your laptop's slot length and keying first.
    Is a heatsink needed?
    For sustained Gen 4 transfers a heatsink helps keep speeds steady. Many desktop boards include an M.2 heatsink; slim laptops usually have none.
    How long will the 1TB model last?
    It is rated at 512 TBW, which covers years of typical desktop use. Heavy write workloads will use that up faster.
    What is in the box?
    The drive itself. Mounting screws are usually supplied with the motherboard or laptop, not the drive.
    Does it have a DRAM cache?
    The published specs do not state a DRAM cache or controller model, so treat cache behavior as unconfirmed.
    Where is the M.2 2280 NVMe SSD 1TB PCIe Gen 4 GM988 cheapest?
    At Bestoss, for $539.99, as of our latest check.
    What do buyers say about the M.2 2280 NVMe SSD 1TB PCIe Gen 4 GM988?
