sandisk

Forgive me if this is the wrong thread for removal storage. I bought 2x of these cards recently and they are rated at 200MB/s though both had the exact same serial number on them. I ran some tests, and bought again a new memory card reader, SanDisk Extreme PRO SD UHS-II USB-C Card Reader...

One of my SSDs that holds my MacOS install on my PC has seemingly failed without warning. It was 4 years old (just over the 3 year warranty, well played SanDisk...). It now doesn't appear in Windows on the same machine or even in BIOS, but it does appear in EaseUS backup software...
