SATA SSD module is available as a field-replaceable unit (FRU). The SSD module has a button which facilitates hot-swapping of the module. To prevent data loss, press the hot-swap button to request removal and wait for the system to confirm safe-removal by turning off the status LED.
Lenovo offers a broad range of solid-state drives from the major flash storage vendors. We offer SATA, SAS and NVMe drives to support a variety of workloads and performance needs. This web page allows you to compare the capabilities of the 2.5-inch and 3.5-inch drives available from Lenovo.
Do you need to accelerate the performance of your read intensive applications? HPE SAS Read Intensive (RI) Solid State Drives (SSDs) deliver enterprise features at an affordable price for applications requiring high read IOPS performance. HPE Enterprise SAS RI SSDs transfer data at full duplex (bidirectional) allowing greater I/O bandwidth to alleviate bottlenecks at twice the 6Gb interface of SATA drives. HPE SAS RI SSDs are best suited for mission-critical enterprise applications requiring a strong blend of high read IOPS and low latency. HPE Enterprise SAS RI SSDs are ideal for read caching, social media, web servers and boot/swap workloads. SAS technology continues to be the interface of choice for many workloads for its reliability and 24x7 operation in the enterprise data center.

What is new supporting point:
Offer 960 GB, 1.92 TB, 3.84 TB, 7.68 TB, and 15.36 TB storage capacities on selected models of SAS SSDs.
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.
