M461 vs M470 Pro Specs
Transfer Speed
The M470 Pro leads in raw throughput. It offers sequential read speeds up to 6000MB/s and write speeds up to 5000MB/s. The M461 trails with 5000MB/s reads and 4400MB/s writes. This gap matters for large file transfers. If you move big video files or game libraries often, the M470 Pro finishes tasks faster. The M461 is still fast for general use. You will notice the difference in heavy workloads. Choose the M470 Pro for speed. Pick the M461 if you save money.
Endurance
The M461 provides significantly higher endurance. It supports up to 3300 TBW (Terabytes Written). The M470 Pro offers only 640 TBW. This is a major difference for long-term use. High TBW means the drive can handle more data over its life. The M461 is better for heavy writing tasks. You write more data daily, the M461 lasts longer. The M470 Pro is fine for light use. Check your usage habits. Heavy users should pick the M461. Light users might prefer the M470 Pro.
NVMe Standard
The M461 uses the newer NVMe 1.4 standard. The M470 Pro uses NVMe 1.3. Both use PCIe Gen4x4 interfaces. NVMe 1.4 brings minor efficiency improvements. It may offer better power management. The M470 Pro is still very capable. The difference is subtle for most users. You might not notice the version change. The M461 has the technical edge. It follows the latest protocol. The M470 Pro is older but proven. Both standards support high speeds. Pick the M461 for the latest spec.
Physical Dimensions
The M461 lists specific dimensions. It measures 6.40 x 3.30 x 0.80 inches. The M470 Pro data does not list size. Both use the M.2 2280 form factor. This means they fit standard slots. The M461 has a known weight of 1.41 ounces. You know exactly what you get with the M461. The M470 Pro size is unknown. This matters for tight cases. If space is tight, the M461 is safer. You can plan your build better. The M470 Pro might be different.
Interface Type
Both drives use PCIe Gen4x4 interfaces. They are internal NVMe drives. The M470 Pro title mentions Portable SSD and USB-C. This suggests it may be an external drive. The M461 is clearly an internal drive. You need a motherboard slot for the M461. The M470 Pro might plug into a USB port. Check your needs. Do you want internal or external? The M461 is for internal installs. The M470 Pro might be external. Verify the connection type. This is a key difference.
Which MSI Spatium SSD fits you
Users needing high endurance for heavy writes
The M461 offers 3300 TBW, far exceeding the M470 Pro's 640 TBW. This makes it better for sustained workloads. If you edit large video files or run databases, the higher endurance protects your data longer. The M470 Pro's lower TBW suggests it is less suited for constant heavy writing tasks.
Gamers prioritizing maximum sequential read speeds
The M470 Pro reaches 6000MB/s read speeds, beating the M461's 5000MB/s. Faster reads can reduce load times for large game assets. If raw throughput is your main metric for performance, the M470 Pro provides a clear advantage in sequential data access compared to the slightly slower M461.
Those wanting portable external storage convenience
The M470 Pro is listed as a Portable SSD with USB-C host interface. This allows easy connection to laptops or consoles without an internal slot. The M461 is an internal drive only. If you need to move data between devices quickly, the portable design of the M470 Pro is the practical choice.
