Featuring 144-Layer, TLC, 3D NAND, the Solidigm™ D3-S4520 and Solidigm™ D3-S4620 Series SSDs are designed to reduce storage operating cost, accelerate read-intensive and mixed workloads with power-efficient performance, and improve overall system reliability and flexibility while preserving legacy infrastructure.
Download the Product Brief or read on to discover ways the highly-efficient Solidigm D3-S4520 and D3-S4620 can reduce storage operating costs and accelerate read-intensive and mixed-use workloads with power-efficient performance compared to HDDs.
These reliable SSDs meet demanding service level requirements while increasing server efficiency. The fourth-generation controller and innovative firmware paired with the latest generation of I3D NAND make the Solidigm D3-S4520 and D3-S4620 Series compatible with existing SATA deployments for an easy storage upgrade.
Built for compatibility with legacy infrastructures, the D3-S4520 and D3-S4620 reduce the costs associated with modernizing your data center. Available in a variety of capacities from 240GB up to 7.68TB, and in standard 2.5-inch and M.2 80mm form factors, the larger capacity drives consume up to 5x lower power and have up to 5x lower cooling requirements than 2.5-inch HDDs.  The D3-S4520 also enables 3.2x more data to be stored in the same amount of space. 
Simply by integrating SSDs into the environment, organizations can improve server agility with up to 245x more IOPS/TB than HDDs,  supporting more users and better services to grow the business without expanding the server footprint. The Solidigm D3-S4520 and D3-S4620 are up to 6.7x more bandwidth-efficient in sequential workloads as well,  allowing an upgrade to hybrid or all-flash sotrage to more easily fit within existing cooling solutions.
Additionally, the Flex Workload feature enables a common drive type to cover more workloads with flexible capacity, endurance, and power-efficient performance.
The reliability of the D3-S4520 and D3-S4620 SSDs reduces the need for drive replacement that is necessary with HDDs. With an actual annualized failure rate (AFR) up to 1.9x lower than HDDs,  IT departments will spend less time and expense replacing or upgrading storage devices. Equally important, once the SSDs are installed, the innovative SATA firmware completes updates without reset, reducing downtime.
For years, Solidigm has been a leader in providing trusted data center SSDs that maximize data continuity in enterprise and cloud data centers. That reputation continues with the D3-S4520 and D3-S4620 SSDs and their key capabilities that help ensure more uptime:
