ST400FM0303 Seagate Nytro 1200.2 400GB SAS 2.5" Server SSD

High-Performance 2.5in SAS Enterprise SSD featuring power-loss protection with the ST400FM0303

The ST400FM0303 is a 2.5in internal SAS hot-swap enterprise SSD engineered for mixed read/write server tiers where predictable latency matters more than peak throughput. Integrated into modern CPU platforms with SAS HBAs or RAID controllers, the ST400FM0303 provides a consistent storage layer for database instances, VM boot volumes, and cache tiers, keeping I/O paths stable under sustained queue depth.

Designed around MLC NAND and endurance-focused firmware, the ST400FM0303 aligns well with servers running dense memory footprints and virtualization stacks that generate small-block traffic. With sequential performance up to 1750 MB/s read and 390 MB/s write and random 4K up to 170K/35K IOPS, it supports consolidation while maintaining service levels. Power Loss Protection helps protect in-flight data during unexpected power events, and the SAS interface simplifies scale-out expansion in PCIe-backed controller topologies without changing drive form factor.

Why Choose the ST400FM0303?

The ST400FM0303 delivers an enterprise-focused density-to-performance profile for 24x7 duty-cycle deployments, combining hot-swap serviceability with write-optimized behavior for logging and metadata workloads. Its 3 DWPD endurance over 5 years (2190 TBW) supports predictable refresh cycles, while SAS interoperability enables straightforward scaling across multi-bay backplanes and redundant controller designs.

Seagate designs the Nytro enterprise SSD portfolio with controlled thermals, firmware stability, and data-centre compatibility as priorities, aligning qualification, reliability testing, and power-management features with the operational requirements of mission-critical rack and blade infrastructures.
