Dell 400-AQFX 800GB MLC SAS 12Gb/s 512N write intensive 2.5-inch solid state drive delivers exceptional write performance, ultra-low latency, and enterprise-grade endurance for Dell PowerEdge

400-AQFX – Dell 800GB Multi-Level Cell (MLC) SAS 12Gb/s 512N 2.5-Inch Write Intensive Solid State Drive

The Dell 400-AQFX 800GB Solid State Drive (SSD) is a high-performance enterprise flash storage solution designed for write-intensive workloads in Dell PowerEdge servers and enterprise data center environments. Featuring a SAS 12Gb/s interface, Multi-Level Cell (MLC) NAND flash technology, 512N sector format, and Write Intensive (WI) optimization, this SSD delivers exceptional write performance, ultra-low latency, and enterprise-grade endurance for mission-critical applications.

Built in a compact 2.5-inch Small Form Factor (SFF), the drive significantly improves application responsiveness, transaction processing speeds, and overall system efficiency compared to traditional hard disk drives. The high-speed SAS 12Gb/s interface ensures superior bandwidth, reliable data transfer, and enhanced data integrity in demanding enterprise environments.

The MLC NAND architecture provides greater write endurance and long-term reliability than standard consumer-grade flash technologies. Optimized for write-intensive workloads, the Dell 400-AQFX is ideal for enterprise databases, virtualization platforms, online transaction processing (OLTP), ERP systems, financial applications, analytics environments, and high-performance computing workloads.

The 512N (512-byte native) sector format provides compatibility with enterprise operating systems and applications requiring native 512-byte sectors while maintaining optimal performance.
