I was specifically looking for a small capacity M.2 SATA drive for my Raspberry Pi4 Argon 1 M.2 case, so it was perfect for my needs but may not be right for yours. I quickly got the Pi up and running. Any issues are related to the Argon 1 M.2's casing rather than the drive itself. I have no complaints, but be careful when buying.
