It's an odd excuse to trot out for Patriot. Is there any product line that's more overloaded with competitors than the USB memory sticks? Yet Patriot has at least two brand-names in that ocean.
I just hope that their prior consumers can get any needed firmware updates based on SF controller models, but I think SSDs (and Mem Sticks) are pretty crowded not only with brands but models-within-brands. I keep looking at umpteen models by any one manufacturer and my gut-reaction is, "So what's wrong with the OTHER models?"
Likely, nothing. New Ones are simply better. Hopefully. My next reaction is always, "Buyer beware" because we've all seen examples where a tech product reaches some zenith-model and then starts a slide downhill.
