400-ANNX Dell 960GB SAS-12GBPS 2.5 Inch Hot-plug SSD.

High-Speed SAS 12Gbps Interface for Enterprise Applications

The Serial Attached SCSI (SAS) 12Gbps interface of the Dell 400-ANNX SSD enables faster data transfers, reduced bottlenecks, and reliable full-duplex communication. Compared to SATA alternatives, SAS delivers double the bandwidth, making it ideal for mission-critical environments where latency and performance matter.

Advantages of 12Gbps SAS Over SATA

• Enhanced performance scalability with dual-port capability
• Advanced command queuing for high IOPS scenarios
• Improved signal integrity with better shielding and protocol layering
• Redundancy support for fault tolerance and failover

Optimized for Mixed Use Workloads – 3DWPD Endurance Rating

The Dell 400-ANNX 960GB SSD is categorized as a Mixed Use SSD, balancing performance and endurance for read/write-intensive applications. With an endurance rating of 3 DWPD (Drive Writes Per Day), it’s engineered to handle enterprise workloads including OLTP (Online Transaction Processing), virtualization, VDI, and boot-intensive systems.

Mixed Use SSD Applications

• Virtualization and hyper-converged infrastructure (HCI)
• Database systems requiring moderate to high I/O
• Email servers and collaborative platforms
• Cloud computing and containerized storage environments

DWPD Explained

DWPD, or Drive Writes Per Day, is a critical endurance metric for enterprise SSDs. The Dell 400-ANNX's 3DWPD rating means the drive can handle writing 3x its total capacity every day for the length of its warranty—significantly increasing its lifespan for mixed-use deployments.

3D TLC NAND Technology – Enhanced Density and Reliability

The Dell 400-ANNX SSD uses 3D TLC (Triple-Level Cell) NAND flash, providing increased storage density and lower cost-per-gigabyte without compromising data integrity. By stacking memory cells vertically, 3D NAND technology offers better endurance and performance than traditional planar NAND.

Key Benefits of 3D TLC NAND

• Higher storage density in a compact 2.5-inch form factor
• Improved read/write efficiency and latency
• Advanced wear leveling and error correction
• Reduced total cost of ownership (TCO)

Hot-Plug Capable 2.5-Inch Form Factor for Enterprise Flexibility

The Dell 400-ANNX SSD’s hot-plug capability allows IT administrators to swap or replace drives without downtime. Its 2.5-inch form factor fits standard enterprise server bays, ensuring quick deployment and ease of maintenance in both rack-mounted and tower systems.

Hot-Plug Benefits

• Minimized downtime during hardware replacements
• Improved serviceability in RAID-configured systems
• Efficient scaling of storage in live environments
