U.2 (SFF-8639) is an enterprise-grade interface designed for connecting high-performance SSDs. It supports PCIe, SATA, and SAS protocols, making it versatile for different types of storage devices.
Function: This adapter allows you to connect an M.2 or M.3 SSD to a system’s U.2 (SFF-8639) interface, effectively enabling the use of a smaller, high-speed M.2 or M.3 SSD in a U.2 2.5-inch drive bay.
U.2 SSDs typically come in a 2.5-inch form factor and are used in data centers and high-end workstations due to their speed, durability, and ability to handle intensive workloads.
Bandwidth: U.2 supports PCIe lanes (usually x4), which provides high bandwidth similar to M.2 NVMe SSDs, but it comes with better thermal management, power handling, and serviceability, especially in server environments.
