A bit hypocritical of you to make statements about SSD performance and then not provide any information about tests you conducted, what software you used, etc, and give us an ultimatum about providing you with our data, and tests, etc....I have somewhere in the ballpark of 100 assorted Intel consumer and enterprise SSDs in my lab and have tested hundreds of drives from pretty much every major manufacturer.
While it is true that many low end consumer SSDs are unable to sustain their specified performance for very long, it's equally true that many are cache-less designs which are effectively PLP and sustain steady state performance until the drive is full or exhausts P/E cycles.
I have referred to specifications from the manufacturer's own website and supporting benchmarks for the example I began the discussion with.
I am not particularly interested in discussing this further if will continue to proceed without data or specific implementation details that directly and logically relate the power consumption with any observable quantity.
What drives they were, and the most important part... what performance are they sustaining in steady state? Who cares if a consumer drive can "sustain steady state performance until he drive is full" if that performance is terrible.
