Seagate Nytro 3550 6.4TB Mixed-Use SAS 12Gb/s 2.5" Enterprise SSD

The Seagate Nytro 3550 6.4TB (XS6400LE70085) is a dual-port SAS 12Gb/s 2.5-inch enterprise solid-state drive engineered for mixed-use workloads that demand a balance of sustained read throughput, write endurance, and continuous availability. Built on a 3D TLC NAND architecture with an advanced SAS controller, the drive delivers up to 2,100 MB/s sequential read and 1,700 MB/s sequential write speeds, while its dual-port SAS interface enables active-active multipath configurations that eliminate single points of failure in high-availability server and storage array deployments.

With a 3 Drive Writes Per Day (DWPD) endurance rating sustained over a five-year design life, the Nytro 3550 6.4TB is suited for workloads that mix intensive random I/O with large sequential transfers—including database transaction logs, virtual machine datastores, and analytics acceleration tiers. The drive incorporates Seagate's PowerChoice technology for configurable power states, reducing energy consumption during idle periods without sacrificing responsiveness on resumption. End-to-end data protection, including T10 DIF/DIX support, guards data integrity from the host bus adapter through the NAND media.

The Nytro 3550 occupies a standard 2.5-inch, 15mm z-height SFF form factor compatible with SAS-3 backplanes and backward-compatible with SAS-2 environments at reduced interface speeds. Its enterprise-grade design includes support for sanitize instant erase (SIE) for secure data disposal and hardware-based AES 256-bit self-encrypting drive (SED) capability for compliance with data-at-rest security mandates. These attributes position the Nytro 3550 6.4TB as a high-density, resilient storage component for mission-critical server tiers where uptime and data integrity are non-negotiable.

Ideal for

• High-availability database servers (Oracle, SQL Server, SAP HANA) requiring dual-port multipath I/O for zero-downtime failover and sustained mixed read/write throughput
• Virtualization host storage tiers in VMware vSphere or Microsoft Hyper-V clusters where multiple concurrent VM workloads generate unpredictable mixed I/O profiles
• All-flash and hybrid storage array build-outs using SAS 12Gb/s backplanes that demand dense 6.4TB per-slot capacity with enterprise endurance ratings
• Online transaction processing (OLTP) acceleration where low-latency random 4K reads and writes underpin sub-millisecond application response times
• Analytics and data warehouse query acceleration tiers that stream large sequential data sets while also serving concurrent random lookup requests
• Secure government and financial sector deployments requiring AES 256-bit SED encryption and sanitize instant erase for regulatory data-at-rest compliance
