Sinyiin X873 USB 3.0 NVMe Solid Disk Expansion Module for RPi 4 — 5Gbps, M.2 2280/2260/2242/2230

The Sinyiin X873 is a USB 3.0 to NVMe Solid Disk expansion board built for Raspberry Pi 4, providing a simple and fast method to expand storage. It supports M.2 Solid Disk sizes 2280, 2260, 2242 and 2230. The USB 3.0 interface delivers data transfer rates up to 5Gbps, making large data moves quick and efficient. Activity LEDs indicate read/write status, and the board supports booting the operating system from the Solid Disk for faster application startup and quicker file copying. A convenient power button is included: a single press turns the unit on, holding the button for 3 seconds initiates a safe shutdown, and holding it for 7 seconds forces a shutdown—an important control often absent on RPi 4 setups.
