ASUS ProArt PA40SU M.2 NVMe SSD Enclosure, M.2 2230/2280, 1-Bay, USB4 Type-C, Stealth Black

The ASUS ProArt PA40SU SSD Enclosure Stealth Black is an external storage accessory designed to house a single M.2 NVMe PCIe SSD. USB4 Gen 4 technology provides a theoretical data transfer rate of 40 Gbit/s. It is aimed at users who need access to large data sets away from a fixed workstation. The enclosure connects to the host device via a single female USB Type-C port and supports M-key drives, the standard interface for NVMe internal storage. Its main purpose is to convert an internal NVMe SSD into a portable external drive.

The enclosure is 13.5 mm thick and weighs 127 grams, making it easy to carry between locations. Its Stealth Black finish gives it a neutral look suitable for professional studio settings. It draws power directly from the USB bus, so no external adapter is needed. It is compatible with Windows 10 and 11, as well as macOS 14.5, Sequoia 15.0, and Tahoe 26. Storage temperatures are rated at -40 to 60 °C when the device is not in use. No drive is included; the user must install their own.
