MSI Spatium M461 vs M480 Pro Specs
Transfer Speed
The MSI Spatium M480 Pro leads in raw performance. Its sequential read speed reaches 7400 MB/s, while the M461 tops out at 5000 MB/s. Write speeds follow the same pattern, with the M480 Pro hitting 6000 MB/s against the M461’s 4400 MB/s. These numbers matter for large file transfers, video editing, and loading heavy games. If you move massive datasets often, the M480 Pro’s higher bandwidth reduces wait times. The M461 is still fast for general use, but the M480 Pro offers a significant performance gap for demanding tasks.
Storage Capacity
Capacity is the clear differentiator here. The MSI Spatium M461 provides 2TB of storage space. The MSI Spatium M480 Pro offers 1TB. If you need more room for games, media libraries, or work projects, the M461 gives you double the space. Both drives use the M.2 2280 form factor, so they fit in the same slots. However, you must choose between more storage or higher speed. The M461 is the better choice for users who prioritize space over maximum throughput. The M480 Pro is for those who prefer speed and can manage with less total capacity.
Endurance
Endurance is measured by Terabytes Written (TBW). The MSI Spatium M461 boasts a higher endurance rating of up to 3300 TBW. The MSI Spatium M480 Pro is rated for 700 TBW. This difference is significant for heavy writers. The M461 can handle much more data being written over its lifespan. This makes it more suitable for servers, heavy video editing, or constant large file writes. The M480 Pro’s lower TBW is typical for higher-performance drives that use different cell architectures. For typical desktop users, both will last years, but the M461 offers greater longevity under heavy loads.
Software Features
Software support differs between the two models. The MSI Spatium M480 Pro includes MSI Center software for data migration and disk monitoring. It also comes with Actiphy software for backup and restore functions. The product data for the MSI Spatium M461 does not list specific companion software. If you value easy data migration tools and backup utilities, the M480 Pro provides a more complete package. The M461 relies on standard OS tools or third-party solutions. For users who want integrated management features out of the box, the M480 Pro has the advantage.
Security
Both drives include built-in data protection and error correction capabilities. The MSI Spatium M480 Pro explicitly lists TCG Pyrite encryption and end-to-end data protection in its features. The MSI Spatium M461 mentions built-in data security but does not specify encryption standards in the provided data. TCG Pyrite is a robust standard for full disk encryption. If you require specific hardware-level encryption compliance, the M480 Pro’s listed features provide more assurance. Both protect against data corruption, but the M480 Pro offers more detailed security specifications for sensitive environments.
Which MSI NVMe drive fits your needs
Users needing maximum sequential transfer speeds
The M480 Pro offers significantly higher throughput. Its sequential read speed reaches 7400 MB/s, and write speeds hit 6000 MB/s. This performance advantage matters for large file transfers or heavy workloads. If raw speed is your priority, this drive delivers the fastest PCIe Gen4 experience available in this comparison.
Buyers requiring double the storage capacity
The M461 provides 2TB of storage, double the 1TB capacity of the M480 Pro. It also offers a higher endurance rating of 3300 TBW. This makes it ideal for users who need more space for games or files while ensuring long-term reliability through superior terabytes written specifications.
Those wanting included data management software
The M480 Pro includes MSI Center and Actiphy software. These tools help migrate data and monitor disk status. Actiphy adds backup and restore features to prevent data loss. If you value built-in utilities for managing your drive and protecting your files, this package offers more comprehensive support.
Shoppers prioritizing endurance over speed
The M461 boasts a 3300 TBW endurance rating. This is nearly five times the 700 TBW rating of the M480 Pro. While both drives use M.2 2280 form factors, the M461’s higher endurance ensures it can handle more data writes over its lifespan. Choose this if longevity is critical.
