MSI SPATIUM M461 1TB PCIe 4.0 NVMe M.2 SSD

1TB PCIe 4.0 x4 NVMe M.2 SSD — Up to 5000 MB/s Read, 3200 MB/s Write, PHISON E21T Controller, 3D NAND, NVMe 1.4, Up to 900 TBW, 5-Year Warranty.

The MSI SPATIUM M461 1TB is a mainstream PCIe Gen4 NVMe M.2 SSD aimed at gamers and power users who want a big jump over SATA and older Gen3 drives without stepping all the way up to flagship models. With a PCIe Gen4x4 interface and NVMe 1.4 compliance, the 1TB M461 delivers sequential read speeds up to 5000 MB/s and write speeds up to 3200 MB/s, giving much faster game load times, OS responsiveness, and file transfers on modern platforms.[web:602][web:607][web:603][web:606][web:610] Built around the PHISON E21T controller with 3D NAND flash and rated for up to 900 TBW on the 1TB variant (global spec), the SPATIUM M461 1TB balances strong Gen4 performance, endurance, and value for everyday gaming and productivity builds.[web:608][web:607][web:603][web:606]
