•M.2 2280 form factor with PCIe Gen5 x4 interface and NVMe 2.0 compliance[2][3][6].
•Phison PS5028-E28 controller fabricated on TSMC 6nm process paired with Kioxia 218-layer TLC 3D NAND[1][4].
•DRAM cache scales by capacity: 1GB (1TB model, 1.3M read IOPS), 2GB (2TB model, 2.5M read IOPS), 4GB (4TB model, 2.6M read IOPS)[4].
•Additional features include SLC caching for burst performance, S.M.A.R.T for health monitoring, and security isolation[2][3].
•DLP technology protects DRAM cache contents during power loss to prevent file system corruption[4][5].

MSI SPATIUM M571 DLP will enable broader PCIe Gen5 adoption in consumer desktops without custom cooling.

50% lower power consumption allows reliable operation under standard motherboard heatsinks, reducing thermal barriers for mainstream use[1][5].

Data Loss Protection will become a standard expectation for high-end PCIe Gen5 SSDs.

MSI's industrial-grade DLP addresses a key reliability gap in power-sensitive high-bandwidth drives, setting a new benchmark for the category[4][5].
