I doubt they're writing the whole chip—instead, a statistical sampling seems sufficient.
And wouldn't most controllers already handle accumulating errors, including any introduced by the testing process? I understood that a portion of flash storage is set aside for redundancy.
- Arbalest 8y agoI don't think that is a safe assumption. While good controllers do wear levelling, there are many that have less capable wear levelling. Also, even with reserve blocks, having a constantly full drive can make inferior controllers cause abnormal wear. This is probably less of a problem even with lower end controllers today, but let's not forget the early Sandforce controllers... those chips could be part of the recycling process.
