- •Cards failed to be recognized by devices and couldn't be read on multiple systems

Bottom Line
This card has a split personality—it's genuinely reliable for critical recording work and delivers on storage capacity, but there's a troubling trend of cards failing after a few months and real-world speeds lagging significantly behind advertised specs. While some users swear by SanDisk's durability, the 40% failure rate and speed disappointments can't be ignored. If you're using this primarily for video recording or photography on compatible devices where speed isn't critical, it's a solid pick. However, if you need consistently fast performance or gaming applications, you might want to explore alternatives like Samsung before committing—especially given the mixed reliability track record.
