Lenovo 3DWD 400GB 2.5" SAS SSD

Overview

The Lenovo 01DC482 is a 400 GB solid state drive designed for enterprise storage arrays and rack servers. It uses a 2.5 inch Serial Attached SCSI (SAS) interface to deliver reliable performance, especially in environments with heavy write workloads. Featuring 3D Write Intensive NAND technology, this drive maintains consistent speed and endurance even under frequent data rewriting, making it well suited for transaction-heavy and log-intensive applications.

Its dual-port SAS connectivity allows connection to two separate controllers, providing a failover path that helps keep critical applications online if one path fails. An integrated cache buffer reduces latency during sustained operations, which benefits virtualized environments, database clusters, and analytics platforms that require steady and predictable throughput.
