XS1600LE70045 Seagate Nytro 3550 1.6TB SAS 2.5" Server SSD

High-Availability 2.5in SAS Enterprise SSD for Read-Intensive Tiers with the XS1600LE70045

The XS1600LE70045 is a Seagate Nytro 3550 internal enterprise SSD engineered for 24x7 server boot volumes and read-intensive application tiers where predictable latency and fault-tolerant connectivity are mandatory. Built on TLC NAND with a 2.5in SAS interface, it integrates cleanly into existing SAS backplanes while delivering up to 2200 MB/s sequential read and strong 4K random read performance for fast service start-up and responsive virtualised workloads.

Architecturally, the XS1600LE70045 supports dual-port SAS to enable active-active multipathing and continuous availability across redundant controllers, reducing single-path risk in shared storage arrays. Moderate write endurance at 3 DWPD aligns the XS1600LE70045 to mixed enterprise databases and virtualisation datastores that require sustained performance without the overprovisioning typical of heavy-write devices. Integrated SED capabilities with Seagate Secure encryption support help standardise at-rest protection without introducing application-layer overhead.

Why Choose the XS1600LE70045?

The XS1600LE70045 targets density-to-performance efficiency in 2.5in bays while maintaining enterprise reliability for always-on service tiers. With dual-path SAS and consistent QoS, it scales from single-server boot pools to shared arrays, supporting resilient designs and simplified spares strategy across homogeneous fleets. The XS1600LE70045 also supports operational continuity through high MTBF and controlled power draw for thermally constrained chassis.

Seagate designs Nytro enterprise SSDs around sustained throughput, predictable latency, and long-life qualification for data centre standards. The platform focus is on interoperability in SAS infrastructures, robust firmware validation, and security integration that aligns with enterprise compliance requirements.

Key Applications:

• Server boot and OS volumes
• Virtualisation datastores
• Read-intensive application tiers
