Gen4 GP6450 500GB internal SSD

The Gigastone Gen4 GP6450 is a 500GB M.2 2280 NVMe drive built for consumer PCs, laptops and PS5 consoles. It uses a PCIe 3.0 x4 interface and 3D NAND with SLC cache to deliver responsive storage for gaming and creative workloads.

Capacity and headroom

Rated sequential speeds reach 5,000MB/s read and 2,600MB/s write with 140,000 random read and 200,000 random write IOPS. The 280TBW endurance rating and 1,000,000‑hour MTBF provide headroom for heavy daily use, though sustained write loads will eventually throttle once the SLC cache fills.

AES encryption and LDPC

Built‑in AES 128/256 encryption and TCG OPAL 2.0 compliance secure data at rest without software overhead. LDPC error correction and ECC maintain data integrity across the drive’s lifespan.

Questions about this item

Will the M.2 2280 PCIe Gen 3.0 x4 NVMe interface work in my older laptop that only has a PCIe Gen 3.0 slot?

Yes, the drive uses a PCIe Gen 3.0 x4 NVMe interface and is backward compatible with PCIe Gen 3.0 M.2 slots, delivering up to 5000 MB/s read and 2600 MB/s write speeds.

How can I verify the AES 128/256 encryption and TCG OPAL 2.0 compliance are active after installation?

Use your operating system's drive encryption tool (such as BitLocker) or the motherboard BIOS security settings to enable and confirm hardware-based AES 128/256 encryption with TCG OPAL 2.0 support.

Does the package include a heatsink or mounting screw for the M.2 2280 form factor, or must I buy them separately?

The drive is supplied as a bare M.2 2280 module; a heatsink and the M.2 mounting screw are not included and must be sourced separately if your system requires them.
