About the Samsung 990 EVO Plus Enterprise-class M.2 SSD 4TB
The Samsung 990 EVO Plus Enterprise-class M.2 SSD in the 4TB capacity tier represents Samsung's 2025-Q1 advancement in the hybrid PCIe 4.0 x4 / PCIe 5.0 x2 interface architecture, enabling compatibility across both current-generation and next-generation host platforms without sacrificing bandwidth. Built on Samsung's latest V-NAND technology with an enterprise-class endurance rating, the drive is engineered to sustain write-intensive workloads at the edge, in workstations, and in compact server nodes where the M.2 2280 form factor is mandated. The hybrid lane configuration intelligently negotiates the optimal interface based on host controller availability, delivering sequential read throughput of up to 7,250 MB/s and sequential write throughput of up to 6,300 MB/s under PCIe 5.0 x2 operation.
Ideal for
- Edge server and micro-datacenter OS and data tiering where U.2 or EDSFF slots are unavailable and M.2 density is critical
- AI and machine learning workstation scratch storage for large dataset staging and model checkpoint persistence
- Video production workstations requiring sustained 4K/8K media read and write throughput across long editing sessions
- Virtualization hosts running multiple concurrent VMs with high random IOPS demands on a single compact storage device
- Industrial edge nodes and ruggedized compute appliances demanding high endurance and consistent latency under mixed workloads
- Database caching and log storage tiers in workstation-class systems where PCIe 5.0 host readiness is being phased in
