Lenovo 7N47A00117 400GB 2.5" SAS Internal SSD

Overview

The Lenovo 7N47A00117 is a 400 GB internal solid state drive designed for 2.5 inch hot swap bays commonly found in Lenovo ThinkSystem servers. It features a 12 Gb/s SAS interface that integrates seamlessly with existing server backplanes, enabling faster storage performance without requiring changes to the server architecture. With data transfer speeds up to 12 Gb/s and the ability to handle 197,000 random read IOPS and 50,000 random write IOPS, this drive accelerates demanding workloads such as database queries, virtual machine migrations, and analytics tasks.

Built for continuous data center operation, the drive maintains a power draw of just 9 watts during active use, helping to manage heat output effectively. Its reliability is underscored by a mean time between failures (MTBF) of 2 million hours, supporting long service intervals and predictable maintenance. Compatible with Lenovo ThinkSystem models including SR530, SR650, SR850, and SN550, it offers flexible deployment options as primary storage, RAID expansion, or a ready spare.
