Description

The [EMC Unity 1.92TB SAS SSD](#EMC Unity 1.92TB SAS SSD) (model D4F-2SFXL2-1920) is engineered for flash-optimized storage arrays such as the Unity 480F, 680F, and 880F. Delivering near-zero latency and sustained 300 MB/s throughput, this enterprise SAS SSD accelerates read-intensive workloads and database transactions.

Housed in a rugged metal shell and supporting the 12 Gb/s SAS interface (#12Gb/s SAS SSD), the drive ensures both durability and high availability. With an average seek time of 9 ms and full external power-supply support, it seamlessly integrates into hybrid Unity configurations to boost performance without compromising reliability.

Available in new, refurbished, and open-box conditions (#D4F-2SFXL2-1920), and shipping within 1–3 working days, this [external SSD module](#external SSD module) is ideal for service deployments needing rapid, plug-and-play expansion.

Key Features

  • Capacity: 1.92 TB raw (1.6 TB user-addressable) in a 2.5″ U.2 form factor

  • Interface: 12 Gb/s SAS, up to 300 MB/s sustained transfer rate

  • Performance: 9 ms average seek time for fast random reads

  • Durability: Metal housing, external power-supply support, noise level rated for enterprise racks

  • Compatibility: Certified for Dell EMC Unity 480F, 680F, 880F arrays (#Dell EMC Unity Expansion)

  • Condition Options: New, Refurbished, Open-Box (#enterprise SAS SSD)

  • Package: Includes mounting hardware and full retail packaging

Compatibility

This [EMC Unity 1.92TB SAS SSD](#EMC Unity 1.92TB SAS SSD) is fully validated for Dell EMC Unity 480F, 680F, and 880F storage arrays. It also works in other 12 Gb/s SAS-capable systems that accept U.2 SSDs. Firmware and power-rail specifications match Dell EMC’s requirements to ensure seamless integration and non-disruptive hot swaps.

Usage Scenarios

For hybrid-flash configurations in the [Unity 480F SSD](#Unity 480F SSD) or 680F arrays, these SSDs serve as tier-1 data volumes—accelerating virtual desktop infrastructure (VDI) and online transaction processing (OLTP) workloads. Their low latency and high IOPS reduce application response times and improve user experience.

In data-intensive analytics and big-data pipelines, deploying sixteen or more of these SAS SSDs can dramatically speed up large-scale queries and in-memory computations. The robust metal enclosure and enterprise-grade design (#metal shell SSD) ensure consistent performance under sustained loads.

For remote or branch-office deployments requiring rapid installation, the plug-and-play nature of this [external SSD module](#external SSD module) combined with the included field-install kit simplifies expansion. Lead times of 1–3 days help maintain uptime SLAs.

Frequently Asked Questions

Q1: Why is the usable capacity 1.6 TB when the raw capacity is 1.92 TB?
The drive reserves a portion of flash cells for over-provisioning and wear leveling, which enhances endurance and long-term performance.

Q2: Can this SSD be used in non-Unity systems?
Yes—any 12 Gb/s SAS-compatible U.2 slot supporting enterprise SSDs will work, though Dell EMC Unity arrays are officially certified.

Q3: What conditions are available, and how do they differ?
You can order brand-new units, factory-refurbished drives (with Dell EMC recertification), or open-box returns—all covered by a full 1-year warranty on New and Refurbished stock.

Q4: Is an external power supply required?
Yes. The module relies on an external 12 V power rail provided by the array’s backplane; no separate brick is needed.
