MSI SPATIUM M470 PRO 1000GB

The MSI SPATIUM M470 PRO 1000GB uses the PCIe 4.0 NVMe 1.4 interface to deliver mid-to-high-tier Gen4 performance, targeting a stated throughput of 6000 MB/s read and 4500 MB/s write. To reach those numbers it moves beyond the Phison E16 architecture found in the non-Pro M470 and likely employs a down-binned Phison PS5018-E18 controller or a high-performance DRAM-less alternative like the Phison E21T, paired with 3D TLC NAND and a DRAM cache buffer in E18 implementations. Field notes: the M470 series runs warm under sustained loads and can thermal throttle without a heatsink or motherboard shield; controller revisions can vary due to component swaps, so verify the specific revision; and sustained write speeds will drop after the pseudo-SLC cache is exhausted, stabilizing significantly lower depending on NAND density.

Key Specifications

• Interface: PCIe Gen 4.0 x4, NVMe 1.4
• Form Factor: M.2 2280 (Double-sided or Single-sided depending on NAND density)
• Controller: Likely Phison PS5018-E18 (Down-binned) or equivalent high-bandwidth controller
• NAND Flash: 3D TLC (Triple-Level Cell)
• DRAM Cache: Yes (typically DDR4)
• Sequential Read: 6000 MB/s
• Sequential Write: 4500 MB/s
• Endurance (TBW): Rated for high endurance, generally scaling ~600-700 TBW per 1TB capacity.
• Encryption: Supports TCG Opal 2.0 and Pyrite capabilities (firmware dependent)

Hardware Alternatives

• Corsair MP600 PRO NH 1000GB: Utilizes similar Phison E18 architecture but is allowed to run at higher clock speeds (7000 MB/s), making it a higher-clocked relative.
• Seagate FireCuda 530 1000GB: Shares the same E18-class controller and Micron 176-layer NAND but uses custom firmware for higher endurance and top-tier speeds.
• Western Digital WD_BLACK SN770 1000GB: A DRAM-less alternative with distinct read speeds (5150 MB/s) that can rival the M470 PRO in real-world gaming loading times despite architectural differences.
