The ThinkSystem PM1653 Read Intensive SAS 24Gb SSDs, in capacities of up to 30.72 TB, are next-generation high-performance 24Gb SAS self-encrypting SSDs (SEDs) suitable for a wide range of applications of running on ThinkSystem servers.

Unlike 6 Gb/s SATA drives, the 24 Gb/s SAS interface on these drives supports full duplex data transfer for higher performance, and enterprise-level error recovery for better availability. By combining the enhanced reliability of Samsung NAND flash memory silicon with NAND Flash management technologies, PM1653 SSDs deliver endurance of up to 1 drive writes per day (DWPD) for 5 years, which is suitable for many enterprise applications with read-intensive storage characteristics.

Self-encrypting drives (SEDs) provide benefits by encrypting data on-the-fly at the drive level with no performance impact, by providing instant secure erasure thereby making the data no longer readable, and by enabling auto-locking to secure active data if a drive is misplaced or stolen from a system while in use. These features are essential for many businesses, especially those storing customer data.
The ThinkSystem 5400 MAX Mixed Use SATA 6Gb SSDs are advanced data center SSDs optimized for mixed read-write performance and endurance. These self-encrypting SSDs (SEDs) are based on the Micron 5400 MAX platform and are available in capacities ranging from 480GB to 3.84TB. They are engineered for greater performance and endurance in a cost-effective design, and to support a broader set of workloads.

This product guide provides essential presales information to understand the 5400 MAX SSDs, their key features and specifications, components and options, and configuration guidelines. This guide is intended for technical specialists, sales specialists, sales engineers, IT architects, and other IT professionals who want to learn more about the 5400 MAX SSDs and consider their use in IT solutions.
High Capacity NVMe™ SSD and Disaggregated Storage Architecture
As cloud and scale-out data centers have become more and more disaggregated, storage has been able to scale independently from compute, giving businesses elasticity during peak demands while avoiding data silos and improving TCO. Disaggregating storage is ideal for cloud service providers. It offers a variety of storage services that combine to deliver a higher quality-of-service, improved performance consistency, and higher storage utilization. For scale-out data center customers, disaggregated storage provides managed service providers to effi ciently increase capacity for modern applications processing large unstructured datasets. As workloads grow to petabytes, high capacity, cost-optimized storage SSDs have an increasingly important role to play. The Ultrastar DC SN650 NVMe SSD can reduce those time-to-insights.
