Enterprise SSD for AI Servers: NVMe U.2 vs E1.S vs EDSFF Comparison

2026 / 08 / 10

Storage bottlenecks can limit AI training throughput. Choosing the right enterprise SSD form factor is essential for AI server builds in 2025-2026.

NVMe U.2 (2.5-inch): The Proven Standard

Samsung MZQL23T8HCLS-00A07 (3.84TB) and MZQL27T6HBLA-00A07 (7.68TB) NVMe U.2 SSDs deliver up to 7GB/s sequential read and are widely supported across Dell PowerEdge, HPE ProLiant, and Supermicro AI server platforms. Solidigm D7-P5520 offers cost-effective TLC NAND alternative at 3.84TB.

E1.S and EDSFF: The New Standard for Dense Deployments

Emerging AI server designs from Meta, Microsoft, and cloud providers increasingly use E1.S (9.5mm) or E3.S for higher SSD density per 1U chassis. Topstar is building supply of E1.S NVMe modules for 2025 AI server refresh cycles.
