Samsung 3.84TB NVMe U.2 PCIe Gen 3.0 x4 RI SFF 2.5" SSD PM983 Series MZ-QLB3T80 MZQLB3T8HALS-00007

The Samsung PM983 3.84TB NVMe SSD is an enterprise-class solid-state drive primarily positioned as Read-Intensive (RI), though it is often classified as Mixed-Use (MU) by resellers due to its higher endurance rating. Built on PCIe Gen 3.0 x4 NVMe architecture and housed in a U.2 2.5-inch SFF form factor, the PM983 delivers high throughput, strong random I/O performance, and enterprise-grade reliability for data center workloads.
