Lenovo PM1655 3.2TB SAS Enterprise SSD

The Lenovo PM1655 is a 3.2TB enterprise solid-state drive with a 2.5-inch form factor and a SAS 12Gb/s interface. It uses 128-layer V-NAND technology and carries a 3 DWPD endurance rating for mixed-use workloads. Features include Tagged Command Queuing, end-to-end data protection and advanced power loss protection.

Suited for compatible ThinkSystem

This drive fits the listed ThinkSystem SR, SD, SN, ST and ThinkStation P920 Rack models that accept 2.5-inch SAS drives. Hot-swap capability supports maintenance without downtime. Servers requiring a different interface, a higher DWPD rating or capacities not offered here will need alternative drives.

3 DWPD endurance defines mixed-use suitability

The 3 drive writes per day rating determines whether the SSD matches the write intensity of the target application. Workloads exceeding this endurance level should select a drive with a higher DWPD specification.

Questions about this item

How many full drive writes per day can the 3.2TB PM1655 sustain before endurance becomes the limiting factor?

The drive is rated for 3 DWPD, meaning you can write the full 3.2TB capacity three times every day for the warranty period without exceeding its endurance specification.

What is the typical power draw and thermal output when the SAS 12Gb/s drive runs mixed-use workloads continuously?

The 128-layer V-NAND and advanced power-loss protection architecture are designed for efficient steady-state operation in 2.5" server bays, keeping power and heat within standard enterprise SSD envelopes.

Which Lenovo server backplane and controller combination is required to hot-swap this 2.5" SAS SSD?

The PM1655 is validated for hot-swap in ThinkSystem SR and ST models such as SR630 V2, SR650 V2, SR850 V2 and ST650 V2 when paired with a compatible 12Gb/s SAS RAID controller or HBA.
