While I don’t believe these are using the same internals as what is found in some of the SanDisk Extreme PRO Portable SSD V2 drives that have been having failure issues, it is impossible to know for sure. SanDisk probably has a lot of work to do if they want to restore confidence in their brand, especially considering their handling of problematic drives.
