MSI SPATIUM M450 1TB M.2 2280 PCIe 4.0 x4 NVMe internal SSD SM450N1TBV1

M.2 2280 NVMe drive for PCIe 4.0 systems

The MSI SPATIUM M450 1TB fits the M.2 2280 slot and uses a PCI-Express 4.0 x4 link with NVMe 1.4. The PHISON E19T controller operates without a DRAM cache, relying on Host Memory Buffer support from the operating system. It targets builds that need 1TB of solid-state storage at up to 3400 MBps read and 2400 MBps write.

Sustained load behaviour with 350 TBW endurance

The drive is rated for 350 TBW and an MTBF of 1,500,000 hours, indicating how much data can be written over its lifetime. LDPC error correction and end-to-end data path protection maintain integrity during long write sessions. APST and a 35 mW idle power level help manage thermals inside the 0 °C to 70 °C operating window.

Straightforward M.2 installation

The single-sided 22.00 mm by 80.00 mm board secures with one screw; no cables are needed. Ensure the motherboard BIOS enables PCIe 4.0 for the slot and that the OS supports Host Memory Buffer, otherwise performance drops to PCIe 3.0 speeds. The 2.15 mm thickness clears most laptop and desktop M.2 sockets.
