SSDs use flash technololgy too, but this:

...provided a confirmation that the SSD version of flash is "higher quality".

Meanwhile, I copied as much as I could off the old SD card, and then I
re-formatted it which seems to have revitalized it.  The 4Gig  card is good
enough for temporary storage and transfer of video files until I am done
watching them.

I am also considering the possibility of replacing the 250gig hdd in my trusty
T60 Thinkpad with a 500gig ssd and then "retiring" the laptop to be my music
storage for FLAC or lossless files of my CD collection and for the offline
storage of my growing playlists with Spotify.
