This SSD Benefits Enterprise Workloads

Dell WN3J5 SATA-6GBPS 960GB Enterprise SSD

The Dell WN3J5 SATA-6GBPS 960GB Mixed Use Solid State Drive represents the pinnacle of enterprise storage technology, engineered specifically for data-intensive environments requiring consistent performance, exceptional endurance, and maximum reliability. This 2.5-inch SFF (Small Form Factor) hot-pluggable drive delivers the perfect balance of capacity, speed, and durability for mixed-use applications in modern data centers, server infrastructure, and high-performance computing environments.

Capacity and Interface

With a generous 960GB capacity and SATA 6Gb/s interface, this SSD provides ample storage for operating systems, applications, and frequently accessed data while maintaining compatibility with existing SATA infrastructure. The drive leverages advanced NAND flash technology to deliver exceptional performance within the SATA interface limitations.

Form Factor

The 2.5-inch SFF (Small Form Factor) design allows for high-density storage configurations in limited space environments. Hot-plug capability ensures seamless installation, replacement, and maintenance without system downtime, making it ideal for always-on enterprise environments.

Advanced NAND Flash Management

The Dell WN3J5 employs sophisticated wear-leveling algorithms, garbage collection, and over-provisioning to maximize NAND flash lifespan and maintain consistent performance under heavy workloads. These technologies work in concert to distribute write operations evenly across all memory cells, preventing premature wear on specific sectors.

Read/Write Performance

Engineered for high IOPS (Input/ Output Operations Per Second), this drive excels in random read/write scenarios common in database operations, virtualization, and server applications. The advanced controller efficiently manages multiple concurrent operations without significant performance penalties.

3DWPD Endurance Explained

The 3 Drive Writes Per Day rating indicates that over its warranted lifespan, the drive can withstand the equivalent of three complete drive writes every day. For a 960GB drive, this translates to approximately 2.88TB of writes daily, or over 1PB of writes over a period.

Firmware

Thermal Characteristics

The solid-state design generates less heat than mechanical hard drives, reducing cooling requirements in densely packed server environments. Consistent thermal performance contributes to long-term reliability and stable operation. Rated for standard data center operating temperatures and humidity levels, the Dell WN3J5 maintains reliable performance across typical environmental conditions without requiring specialized cooling infrastructure.

Capabilities

The drive supports comprehensive S.M.A.R.T. (Self-Monitoring, Analysis and Reporting Technology) attributes specifically tailored for enterprise SSDs. These include detailed wear indicators, lifetime write statistics, temperature history, and error logging for proactive maintenance and failure prediction. While a SATA drive, the WN3J5 may support management features compatible with NVMe Management Interface specifications where applicable, providing out-of-band management capabilities in supported environments.

Mixed-Use vs. Read-Intensive vs. Write-Intensive SSDs

As a mixed-use drive, the Dell WN3J5 occupies the optimal balance between read-intensive and write-intensive SSD categories. While read-intensive drives prioritize capacity and cost-effectiveness for predominantly read workloads, and write-intensive drives maximize endurance for write-heavy applications, mixed-use drives provide the versatility to handle balanced workloads efficiently.
