Stan,
I'm sure there can be progress in any technology, but it is surely
true that there was once-upon-a-time, a re-write problem in the
underlying chip technology that goes into today's SSDs. I tend to use
cast off older stuff in my home computing. When, in the past, would
you say that the SSD technology became reliable? It sort of puts a
cutoff on just how old I should put up with. Or did the technology
problems get solved before anything called SSD get offered on the
comsumer market?
And, the rewrite story for thumb drives ( I think that is what the
small, fit in your pocket USB devices are called. ) is the story also
FUD, or do they use a different, inferior technology?
TIA
