Review on Argon ONE M.2 Raspberry Pi SSD Board (Expansion Board ONLY) - Supports B-Keys and B+M Keys - Exclusive Compatibility with Argon ONE V2 Raspberry Pi 4 Cases by Jerry Anderson

Easy installation. This is a great addition for those who bought an Argon 1 and want to add an M.2. I should clarify that this expansion card only uses B or B/M key for SATA SDD M.2. It's fast enough for a Raspberry Pi, but don't expect to use the newer M.2s that PCs use. I installed everything in three minutes and was good to go. Includes instructions for using the power adapter and IR in the case. It's a sleek and durable body. While it would be nice if it had some sort of internal power connector to keep all four USB slots, using just one adapter is enough to connect the M.2 and the Pi. This is my favorite case. There are a few others that can give you a few more degrees of cooling, but for an all-in-one app, this is a must-have. Clean, neat, efficient, affordable GPU. the ability to turn on and off, and it gives the Pi the best case I've used or tried.
