It's not clear to me whether age alone, absent constant use, might lead to failure. When an SSD fails, it's typically instantaneous, and you get no warning. What can be done to reduce the chance of filesystem corruption and data loss on a single USB drive? (I work in a Windows-only environment, Vista and newer.)

They also may be slower and actually wear out the drive faster, due to the requirements of storing additional checksums and redundant information for each file. The magnetism can diminish over time, putting the data at risk, but this can be restored by powering on and reading or writing the data. http://www.datarecovery.net/newsletters/what-kills-flash-drive.aspx
If the drive supports wear leveling, a larger drive will keep more available sectors in the case some wear out. Commonly used file systems like FAT32 or NTFS don't store any data validation information (only on the internal file system itself). that way you have this impulse that helps you see if you have your keys.

Flash drive is featured with small volume (thumb-sized) and very light weight (about 20g), so it’s suitable to carry around. It depends on how catastrophic it would be to you if it failed. And for what it's worth: while NTFS is a better file system all the way around, FAT is the only file system that's recognized by just about anything with a USB They were then largely stable until the fourth year, when the failure rate rose to 11.8 percent. 74 percent of drives lasted beyond the fourth year.
