DELL 0503M7 960GB SAS 2.5″ 12Gb/s Mix Use SSD 503M7 PX05SVB096Y

Dell 0503M7 Product Overview

The Dell 0503M7 (503M7) is an enterprise-class, high-performance Serial Attached SCSI (SAS) solid-state drive designed for 2.5-inch mission-critical server configurations. Engineered with an original Toshiba/Kioxia PX05SV Series (PX05SVB096Y) backend, this drive features an enterprise eMLC (Enterprise Multi-Level Cell) architecture coupled with a dual-port 12Gb/s SAS interface.

Classified as a Mixed-Use (MU) drive, it delivers an optimized balance of high random IOPS performance, low latency, and robust write endurance, making it highly suitable for virtualization, database processing, and high-performance computing (HPC) environments running on Dell PowerEdge infrastructure.
