SSDEP55DX6T4-AX – 6.4 TB Enterprise Pro EP550 SSD – 2.5″ Hot‑Swap, 12 Gb/s SAS (Designed for Dell)
The Axiom SSDEP55DX6T4-AX is a premium 6.4 TB Enterprise Pro EP550 SSD, engineered for Dell PowerEdge systems, offering unmatched reliability and performance for enterprise environments. Delivered in a 2.5″ hot‑swap form factor with a 12 Gb/s SAS interface, this solid-state drive offers consistent high-throughput, low latency, and data integrity features critical for virtualization hosts, database servers, and mixed-use storage arrays. The dual-port SAS design with advanced firmware supports mission-critical, 24/7 data operations.
Features
Built on the proven EP550 platform, the SSDEP55DX6T4-AX combines high-density 3D NAND flash and enterprise-grade controller logic to deliver sustained sequential speeds of up to 2,200 MB/s read and 1,550 MB/s write, with random 4 KB IOPS reaching approximately 230,000 read and 150,000 write. This SSD is specifically validated for compatibility with Dell PowerEdge MX servers such as MX740c and MX840c compute sleds and the Dell PowerEdge XR2 edge chassis
Advanced Options
The 2.5-inch hot-plug design allows for field replacement without system downtime, while dual-port operation provides hardware-level failover for high availability. With an endurance rating of approximately 3 DWPD (Drive Writes Per Day) translating to over 35,000 TB written over its lifetime, the drive ensures high endurance performance under demanding workloads
