You made a good choice.

As you can see on the label, the cards are "Industrial Grade."  This
means, at least, they have SLC (Single Level Cell) flash in them.  SLC
is more data reliable and longer lived than MLC (Multi-Level Cell)
flash.

SLC = store only one bit per flash cell.
MLC = store two (or more) bits per flash cell.  MLC is higher density
for about the same manufacturing cost so sellers like it.  It's fine
for cameras, etc. but not for computer operation uses, in my opinion.

By the label design they are probably from 2002-2003, which is fine
unless they've had very heavy use.  It would be nice to know their
history but, at least they started life as some of the best you could
get.
