Description

StarTech SM22BU31C3R 2-Bay M.2 SATA RAID Enclosure

Overview

The StarTech SM22BU31C3R is a compact, USB-powered enclosure that transforms two M.2 SATA SSDs into a high-performance portable storage solution. It supports RAID 0, RAID 1, BIG, and JBOD configurations, enabling you to prioritize speed, data redundancy, or capacity. This makes it ideal for professionals who need fast access to large datasets or require a reliable backup solution on the go, such as video editors, photographers, or system administrators managing large surveillance archives.

Compatibility

This enclosure supports two M.2 SATA SSDs (B-Key, NGFF) in 2230, 2242, 2260, and 2280 form factors, up to 2TB each. It connects via USB 3.2 Gen 2 (10Gbps) and is OS independent, functioning with Windows, macOS, and Linux systems without requiring driver installation. The enclosure utilizes the ASMedia ASM1352R chipset for robust performance.

Installation Notes

The enclosure is powered directly via the USB 3.2 Gen 2 connection, eliminating the need for an external power adapter. It features LED indicators for drive activity (green) and errors or rebuild status (red), providing clear operational feedback. The aluminum construction aids in heat dissipation, crucial for sustained high-speed operation.
