Lenovo 4XB7A13649 PM1643 3.84TB SAS SSD | Enterprise Storage, 3.5 in

Maintain critical storage capacity with 3.84TB of SAS solid-state storage in a 3.5-inch enterprise drive format. This Lenovo drive is aimed at infrastructure teams that need substantial flash capacity for production systems, where serviceability and support continuity matter as much as raw storage density. The SAS interface is a strong fit for enterprise arrays and server platforms that depend on mature storage connectivity and predictable behavior under sustained workloads. With 3.84TB available in a single drive, it helps reduce drive count in capacity-focused deployments and can simplify planning for replacement cycles, spare pools, and maintenance operations. This model also carries Lenovo depot service coverage, including parts replacement and labor for three years. That matters when the purchase decision is about more than hardware alone. For teams protecting uptime and budgeting around supportability, the combination of high-capacity flash and service-backed coverage helps justify the premium over lower-tier alternatives.
