Samsung PM9A1 1TB M.2 2280 NVMe SSD

This Samsung PM9A1 drive is a 1TB internal solid-state drive built in the M.2 2280 form factor. It serves as a direct replacement part for compatible laptops requiring a PCI-Express 3.0 x4 NVMe storage device. The unit is new and carries part number MZVL21T0HCLR-00BD1.

Fits laptops with M.2 2280 PCIe 3.0 x4 slots

Installation requires an M.2 2280 slot keyed for PCI-Express 3.0 x4 NVMe signalling. The drive draws power directly from the motherboard connector, freeing the 2.5-inch drive bay for other uses or leaving it empty. No cables or mounting brackets are included with this replacement part.

Replaces failed or smaller M.2 NVMe modules

This part replaces a failed Samsung PM9A1 or compatible drive matching part numbers KG5N3, 0KG5N3 or KR-0KG5N3. The upgrade is worthwhile when the original module has failed or when the existing capacity is insufficient for the workload. Verify the exact part number before ordering because most modules are not interchangeable.

Questions about this item

What is the maximum sustained throughput before the PCI-Express 3.0 x4 interface saturates?

The drive uses a PCI-Express 3.0 x4 interface, so sustained throughput is limited to the bandwidth of that link.

How much heat does the M.2 2280 form factor generate during continuous all-day operation?

The M.2 2280 form factor has no active cooling; heat dissipation depends on the laptop's thermal design and airflow around the slot.

Which laptop models accept the MZ-VL21T0A without an adapter or bracket?

Compatible part numbers include KG5N3, 0KG5N3 and KR-0KG5N3; verify your original part number matches one of these before installing.
