Damn close, but not quite. That article Anand put out during the height of TRIM-gate after discovering the permanent speed-degradation designed into the early drives as they filled up (fixed in all newer controller designs FWIW).

The one I had in my brain was one done after that, it was focused on the SandForce SF-2k series (might have been the 2500) where Anand goes through all of the features in the controller pertaining to data safety. The way it is explained and marketed makes it sound like an SSD will fail once every 15 years, but in reality their failure is horrible... I have no idea why the massive discrepancy. Either these NAND chips are MUCH more volatile than we are being told and Anand's numbers are based on (he has calculations to determine failure rates based on load balancing) or the data parity/recovery systems in these controllers are so insufficient that they underestimate the actual data loss occurring on these things and thus underperform.

Thanks for trying to dig it up though, that article along is certainly worth a read for anyone interested in this topic.
