Closer to < 10 years for hard drives, SD Cards and USB sticks. All of the combine controller electronics with the storage medium itself, which is another point of failure, and one not easily repaired. Their lack of electrical isolation from a host, combined with their lack of true write protection, makes them vulnerable during read. Sadly, 5.25" internal Blu-ray drives are all but extinct now, though USB-C variants are still somewhat readily available with transports from Hitachi-LG.
