Pros: I bought this floppy 5 years ago. It's worked every time I went to use it (like all 10 times). No complaints. I actually bought this same one for my brother when I built his computer last year, too.
Summary: I'm a big Samsung fan. They build quality products. Don't know what happened, in that two separate purchases would fail. But, the replacements have been working without issues for over 1 year. Must have been a QC problem for a limited period of time.
Pros: High quality construction, attractive color, fast, quiet
Cons: Original failed within two weeks of use. Same issue on the second one I bought, had to RMA it.
