Lenovo PM1645a 1.6TB 2.5" SAS 12Gb/s Mixed Use 1000 MB/s Hot Swappable Internal SSD

The Lenovo 4XB7A17063 is a 1.60 TB solid state drive built for enterprise servers and workstations that accept a 2.5 inch SAS 12 Gb/s bay. It delivers up to 1000 MB per second for both sequential reads and writes, making it a straightforward upgrade for administrators who need higher throughput without changing the existing storage fabric.

Engineered for mixed workloads, the drive supports an endurance rating of three complete writes of its capacity every day. This durability is well suited to online transaction processing, virtual desktop pools, and active log capture, where data blocks are updated continually.

Lenovo includes features that safeguard data at every step. End to end protection verifies each transfer, an onboard supercapacitor preserves in-flight data during an unexpected power loss, and S.M.A.R.T monitoring keeps IT staff informed of drive health. The hot swap design means technicians can add or replace drives while the server stays online.

Because it balances speed, endurance, and strong data integrity, the drive fits naturally in ThinkSystem racks, clustered databases, high performance compute nodes, and any environment that needs storage with reliable performance and low latency.

Highlights:

• 1.60 TB capacity on a SAS 12 Gb/s interface
• Up to 1000 MB/s sequential read and write speed
• Three drive writes per day endurance rating
• End to end data protection architecture
• Hot swap capability for live server maintenance
• 128 command queue depth for highly parallel I/O
• Built in power loss protection
• S.M.A.R.T monitoring for proactive health checks
