ST800FM0043 Seagate 1200 800GB SAS 2.5" SSD

High-Endurance 2.5-inch SAS Enterprise SSD for Mixed-Use Write-Intensive Tiers with the ST800FM0043

The ST800FM0043 is a 2.5-inch SAS enterprise SSD engineered for servers and storage arrays that depend on predictable latency under sustained write pressure. Designed for hot-swap SAS backplanes, the ST800FM0043 integrates cleanly into dual-controller architectures where consistent queue handling and deterministic behavior matter for transactional and virtualised stacks.

For modern CPU platforms running dense VM estates or database nodes, the ST800FM0043 supports fast boot and resilient cache/metadata layers while maintaining endurance headroom for continuous logging and commit-heavy operations. Its SAS interface aligns with enterprise PCIe expansion strategies by keeping storage traffic on the SAS domain, preserving PCIe lanes for NICs, HBAs, and accelerators. In tiered storage designs, the ST800FM0043 enables write-intensive hot tiers that protect capacity drives from random-write amplification, improving overall service stability and rebuild behavior.

Why Choose the ST800FM0043?

The ST800FM0043 delivers an enterprise-balanced density-to-endurance profile for SAS infrastructures that cannot compromise on availability. With 10 DWPD over 5 years, the ST800FM0043 is suited for mixed-use workloads where write intensity is sustained rather than bursty, helping standardise drive classes across clusters. The ST800FM0043 also supports scalable deployment in homogeneous bays, simplifying spares strategy and minimizing operational variance across nodes.

Seagate designs the Nytro portfolio with a reliability-first approach focused on controlled performance, firmware validation, and compatibility with enterprise SAS storage standards, enabling consistent integration across servers, JBOD/JBOF shelves, and RAID/HBA ecosystems.

Key Applications:

• Server OS boot and resilient boot mirroring
• Read-heavy caching tiers with write protection
• OLTP logging and transactional databases
• VDI and virtualisation hot data tiers
• SDS metadata and write-intensive journal layers
