Lenovo PM1655 1.60 TB Solid State Drive - 2.5" Internal - SAS (24Gb/s SAS) - Mixed Use

The Lenovo PM1655 1.60 TB Mixed-Use SAS 24Gb/s solid state drive is engineered for data centers that demand reliability, speed, and scalable performance. As the successor to the PM1645a, the PM1655 delivers enhanced endurance and optimized performance for mixed-use workloads—from data-intensive databases and virtualization to heavy I/O streaming and transactional processing. Built for ThinkSystem servers, this 2.5-inch internal SAS SSD leverages a 24Gb/s SAS interface to accelerate read/write operations while maintaining dependable, enterprise-grade durability in 24x7 environments. If you’re upgrading aging storage or consolidating workloads, the PM1655 helps reduce latency, boost IOPS, and improve overall system responsiveness.

• The PM1655 blends high-speed SAS 24Gb/s connectivity with enterprise-grade reliability to support mixed-use workloads across virtualization, databases, analytics, and mission-critical applications. It’s designed to deliver strong sequential and random I/O performance, helping operations handle spikes in demand without compromising consistency. In environments where every millisecond of latency matters, the PM1655 helps keep response times predictable and end-user experiences smooth.
• Designed for ThinkSystem servers, the PM1655 integrates seamlessly with Lenovo management tools and data-center ecosystems. This drive is built to endure round-the-clock operation and is optimized for predictable write patterns common in mixed-use workloads. With robust error correction, wear leveling, and data-protection features, it maintains data integrity while sustaining sustained throughput—vital for large-scale deployments, virtualization clusters, and high-transaction applications.
• Capable of supporting substantial storage density, the PM1655 provides a reliable solution for capacity-constrained environments that still demand fast access to data. The 1.60 TB capacity enables larger datasets, more virtual machines per host, and expanded catalogs or databases without expanding rack space. IT teams can consolidate storage pools, simplify backup strategies, and reduce total cost of ownership by leveraging a single, scalable SAS SSD across multiple workloads and servers.
• Endurance and efficiency are central to the PM1655 design. The drive’s architecture emphasizes write durability and energy-conscious operation, helping data centers manage total power usage while preserving performance. Enhanced error detection, error correction, and firmware optimizations contribute to long-term reliability under diverse and mixed workflows. For environments with dense server configurations, the PM1655’s balance of performance and endurance translates into steadier service levels and lower maintenance windows.
• Security and data protection are woven into the PM1655’s capabilities. Enterprise-grade features—such as power-loss protection, data integrity checks, and compatibility with Lenovo’s ThinkSystem security framework—help guard against unexpected outages and maintain data consistency across events. This is especially valuable for virtualized workloads, databases, and I/O-intensive applications where safeguarding information and minimizing data loss are top priorities.

How to install Lenovo PM1655

Installing the PM1655 2.5-inch SAS SSD is straightforward in compatible ThinkSystem servers and other enterprise platforms that support 2.5-inch SAS drives. Before you begin, power down the server and follow your facility’s electrostatic discharge (ESD) precautions. Remove the drive bay or insert the PM1655 into an available 2.5-inch SAS hot-swap slot according to your server’s hardware guide. Align the drive, slide it into the bay until it seats firmly, and secure the drive tray or sled as required. Connect the SAS data ribbon or backplane cables to the drive’s interface, ensuring a clean, snug fit to avoid contact with edges or mounting hardware. After securing the drive, power up the server and enter the BIOS/UEFI or dedicated server management utility to confirm the drive is recognized. Configure the drive in the operating system or storage array controller as you would with any enterprise SSD, including initializing, formatting, and adding to a storage pool or virtual disk. For best results, update to the latest firmware and monitor drive health through Lenovo’s management tools or your preferred storage administration software. When used in multi-drive configurations, ensure proper zoning, pacing, and redundancy to maximize performance and reliability.
