256GB NVMe SSD for system builders

The Samsung PM9A1 MZ-VL2256A is a 256GB M.2 2280 internal solid-state drive. It connects through a PCI-Express 3.0 x4 interface using the NVMe protocol. The part number is MZVL2256HCHQ-00BD1 and the firmware revision is 36303029. It suits integrators replacing a failed drive or adding primary storage to a compatible laptop or desktop.

Thermals and power in daily use

With no moving parts the drive runs silently during normal workloads. Power draw stays low because the PCIe 3.0 x4 link and NVMe controller are optimised for efficiency. Heat output is modest enough for typical M.2 slots without extra cooling. The 100% functional guarantee confirms each unit passes full inspection before shipment.

Upgrade path and when it matters

This drive replaces an older PCIe 3.0 NVMe stick of equal or smaller capacity that has worn out or become too small. The jump is worth it when the original part number matches MZVL2256HCHQ-00BD1 or the listed compatible numbers R4DT2 0R4DT2 KR-0R4DT2. It does not suit buyers who need more than 256GB of space or a PCIe 4.0 interface.

Questions about this item

How do I install the M.2 2280 NVMe PCIe 3.0 x4 drive in my laptop slot?

Align the notched edge with the keyed M.2 socket, insert at a 24-degree angle, press flat, and secure with the single retention screw; the step most people miss is tightening that screw before closing the case.

What maintenance or replacement will the PM9A1 256GB SSD need over time?

The drive has no moving parts and requires no scheduled maintenance; replacement is only needed if the NAND wears out after heavy write cycles or if the controller firmware 36303029 develops an unresolved error.

What limit appears first during sustained heavy writes on this PCIe 3.0 x4 SSD?

The PCIe 3.0 x4 interface caps sequential throughput, so the controller throttles first when the thermal limit is reached during long, continuous write workloads.
