How to read this comparison
Manufacturer facts for the exact models shown. Not a quality rating or a test result.
“Different” means the known values differ, not that one is better.
Missing or conflicting evidence is marked and never counts as a difference. Source chips hold each fact’s sources and conditions.

MSI SPATIUM M450 V1PCIe 4.0 x4; NVMe 1.4
Manufacturer specification · MSI lists compatibility with PCIe Gen4, Gen3, Gen2 and Gen1 hosts; earlier generations limit speed.
Check the connection before the capacity. M.2 NVMe modules and 2.5-inch SATA drives are not interchangeable. Check the host’s protocol, slot or bay, power connection and clearance. Rated speeds use different test systems; we do not turn them into a speed score or overall winner.
Manufacturer specification · 1 TB value (500 GB: 150; 2 TB: 700); not a guaranteed failure point. The data sheet lists 500GB, 1TB and 2TB columns in that order; a single value spans all capacities.
Manufacturer specification · Listed as 'Pyrite (Encryption, Data Security)'. Listed security capabilities do not mean encryption is enabled or supported by every host.
Listed encryption support does not mean it is enabled. Check the exact host, software and configuration requirements; no security certification is inferred.
Manufacturer specification · Official feature block describes health monitoring and updates; current OS/version prerequisites require separate checking.
Check the software, operating-system and licence requirements. An available feature does not establish a measured speed improvement or support on every host.

It is limited to PCIe 3.0 x4, so it cannot use the extra bandwidth of a PCIe 4.0 or 5.0 M.2 slot, and writes drop from 2,500 MB/s to 1,200 MB/s once the TurboWrite cache fills.
