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 M460PCIe 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 · MSI up-to claims measured as a secondary drive on an AMD Ryzen 7 3700X / MSI MEG B550 / Windows 11 Pro 21H2 system, using CrystalDiskMark, ATTO Disk Benchmark and IOmeter. MSI does not list a post-cache write speed. The data sheet lists 250GB, 500GB, 1TB and 2TB columns in that order; a single value spans all capacities.
