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

MSI SPATIUM M450 1TB NVMe SSD

The MSI SPATIUM M450 is an internal solid-state drive built for consumers who need fast storage in a compact M.2 2280 form factor. It uses a PHISON E19T controller with 3D NAND flash and connects through a PCI-Express 4.0 x4 interface running NVMe 1.4. The drive suits desktops and notebooks alike for gaming, content creation and professional workloads.

Capacity and endurance headroom

With 1TB of usable space the drive holds operating systems, applications and large media libraries without crowding. It is rated for 600 TBW and an MTBF of 1,500,000 hours, so sustained write workloads such as video editing or game installs stay well within endurance limits. Heavy database or logging tasks that exceed the TBW figure will eventually wear the NAND, so plan capacity accordingly.

PCIe 4.0 x4 NVMe 1.4 practical limits

The PCIe 4.0 x4 link caps sequential throughput at 3600 MB/s read and 3000 MB/s write, while random performance reaches 420,000 IOPS read and 550,000 IOPS write. Real-world speeds depend on motherboard lane allocation, thermal conditions and OS support for features like TRIM and APST. On platforms limited to PCIe 3.0 the drive will fall back to lower bandwidth.
