Samsung PM991 256GB NVMe SSD

This Samsung PM991 MZ-VLQ2560 is a 256GB NVMe solid state drive built for internal laptop storage upgrades. It uses the M.2 2280 form factor and a PCI-Express 3.0 x4 interface. The drive suits owners of compatible notebooks who need a direct replacement part.

Compatibility checklist before ordering

Verify that your laptop accepts an M.2 2280 NVMe module with a PCI-Express 3.0 x4 electrical interface. Cross-reference the original part number against L65187-002 or L85354-005 and confirm the firmware revision HPS4NFXV matches your service manual. The drive ships without cables, brackets or manuals.

Upgrade context for this capacity

This 256GB unit replaces a failed or lower-capacity NVMe stick of the same physical and electrical specification. The jump makes sense when the original drive has failed or when the system requires this exact part number for firmware alignment. It does not suit builds needing a larger capacity or a different interface standard.

Questions about this item

Does the MZ-VLQ2560 come with any cables or mounting hardware, or must they be purchased separately?

The drive is supplied without cables, manuals or mounting screws. You will need to reuse the screw from your laptop or obtain one separately.

The part number MZVLQ256HAJD-000H1 is listed alongside L65187-002 and L85354-005 — which one should I match to my laptop?

Match the exact part number printed on your original drive. The three numbers are cross-references; your service manual will show which applies to your model.

What does the PCI-Express 3.0 x4 interface mean for real-world speeds once the drive is installed?

The x4 lane Gen3 link caps sequential throughput at roughly 3.0 GB/s, so large file transfers will hit that ceiling in a compatible M.2 2280 slot.
