1. The EVO issue has been fixed. The new FW is not a band-aid. Its just clickbait wording that websites reporting on it used.
2. Pros will always outlast EVOs.
3. Drives that are sold used, do not have nay warranty. Also, drives that are purchased new and unopened from a non-certified reseller (think someone on ebay named guy21 selling a drive he never opened) there is no warranty.
