SSD disk Solidigm 240 GB 2.5 inch SATA III D3-S4520

The Solidigm D3-S4520 is a 240 GB 2.5" SATA III SSD designed for servers and workstations. Built with 144-layer TLC 3D NAND and a fourth-generation controller, this drive delivers improved IOPS/TB and read/write responsiveness compared with traditional HDDs while remaining compatible with existing SATA infrastructures. Typical sequential performance is up to 470 MB/s read and 233 MB/s write, offering a compact, power-efficient storage upgrade for read-intensive and mixed workloads.

Advantages

This SSD reduces operating costs by enabling higher data density and lower power and cooling requirements compared with 2.5" HDDs. It provides significantly higher IOPS/TB and better bandwidth efficiency for sequential workloads, while the updated controller and firmware improve reliability and allow firmware updates without a full system reset. The drive’s standard 2.5" form factor ensures straightforward replacement in legacy SATA deployments.

Suitable for

• Server read-intensive workloads and mixed-use environments
• Workstations requiring faster boot and application load times
• Data center upgrades that must preserve existing SATA infrastructure
• Environments needing lower power and cooling footprints

Key specifications

• Form factor: 2.5" SATA III
• Capacity: 240 GB
• Read speed (sequential): up to 470 MB/s
• Write speed (sequential): up to 233 MB/s
• NAND: 144-layer TLC 3D NAND
• Optimized for read-intensive and mixed workloads

How to use

Install the Solidigm D3-S4520 into a compatible 2.5" SATA bay and connect to a SATA III interface. Initialize and format the drive using the host operating system or storage management tools, then migrate data or deploy the drive as part of a server or workstation storage array. No special hardware modifications are required when replacing a 2.5" SATA HDD.

Recommendations

Use the drive in systems with SATA III support to achieve specified sequential speeds and to maximize IOPS/TB benefits. For large-scale deployments, monitor drive health through system management tools and schedule firmware updates during maintenance windows to minimize disruption.
