Mainstream M.2 SSD at up to 7,250 MB/s reads with dual-mode PCIe 4.0 x4 or 5.0 x2 connectivity, up to 4 TB.
Product briefing
The 990 EVO Plus covers the mainstream performance tier with up to 7,250 MB/s sequential reads from a DRAM-less HMB design. Its interface operates as either PCIe 4.0 x4 or PCIe 5.0 x2, an unusual flexibility that suits lane-constrained notebooks and next-generation platforms alike.
Samsung's eighth-generation V-NAND and power-efficiency tuning make the drive a strong fit for OEM notebooks and everyday desktop upgrades where thermals and battery matter more than peak benchmark numbers. Capacities run 1 TB to 4 TB with a five-year warranty.
