Lenovo 01DC477 800GB 2.5" 3DWD SAS SSD

The Lenovo 01DC477 is a solid state drive that delivers 800GB of storage through a SAS interface and fits standard 2.5 inch bays. Engineered specifically for Lenovo Storage D1224 4587 systems, it installs quickly and operates as a native component, giving administrators a seamless path to expand or replace capacity without compatibility concerns.

An endurance rating of 3 drive writes per day means the drive can be written to fully three times every 24 hours throughout its service life. This level of durability makes it a dependable choice for write-intensive tasks such as transactional databases, real-time analytics, or high-frequency log capture, where constant data updates are the norm.

The SAS connection provides steady throughput and robust error handling that enterprise environments demand. Whether the drive is part of a virtualized host pool, a high-availability cluster, or a dedicated backup tier, it maintains consistent performance under sustained load.

Support for hot swap lets IT staff pull and replace the drive while the system stays online, minimizing planned downtime and simplifying routine maintenance. Data center teams, managed service providers, and businesses that run mission-critical applications will appreciate the ability to keep workflows active while servicing storage hardware.
