AGI AI818-43 2TB NVMe M.2 SSD

The AGI AI818-43 is a 2TB internal solid state drive built for consumer desktops and laptops that accept an M.2 2280 module. It uses 3D NAND flash and connects through a PCIe 4.0 x4 interface. A graphite heat sink is included to help manage thermals during sustained workloads.

PCIe 4.0 x4 sequential limits

The drive is rated for sequential reads up to 5200 MBps and sequential writes up to 4700 MBps over the PCIe 4.0 x4 link. Actual throughput depends on the host controller, available lanes and thermal conditions. The graphite heat sink helps sustain performance by keeping the controller within its 0°C to 70°C operating range.

M.2 2280 slot and clearance check

Verify that your motherboard or laptop provides an M.2 2280 slot wired for PCIe 4.0 x4 and that the BIOS supports NVMe boot if required. The module measures 80 mm by 22 mm and is 5.4 mm thick with the heat sink fitted, so confirm clearance around the slot. The drive operates on 3.3 V power and is rated for 1200 TBW endurance.

Questions about this item

Should I pick the 512GB, 1TB or 2TB version of the AI818-43?

The 2TB model shown here offers 1200 TBW and up to 5200/4700 MB/s sequential speeds. The smaller 512GB and 1TB versions share the same PCIe 4.0 x4 interface and graphite heat sink but have lower endurance ratings.

What do the 5200 MB/s read and 4700 MB/s write figures mean once the drive is installed?

Those are peak sequential numbers measured under ideal conditions. Real-world game loads, OS boots and file copies will be lower, but the PCIe 4.0 x4 link and 3D NAND still deliver noticeably faster throughput than PCIe 3.0 drives.

Does the PCIe 4.0 x4 interface limit performance on a PCIe 3.0 motherboard?

The drive is backward compatible and will run at PCIe 3.0 x4 speeds on an older slot, capping sequential throughput at roughly half the rated 5200/4700 MB/s while retaining full NVMe protocol support.
