I advise against buying Samsung NVMEs for the following reason: Samsung has found that there were problems with firmware version 3 in 2021 that make the NVMEs unusable in a very short time. The necessary firmware update is available - but can only be installed under Windows. This company policy is unacceptable, because I have paid for performance and receive poor (or no) service. Now I have to remove all my NVMEs, put them into a Windows computer, test them, update the firmware and put them back again.
