Newly published research purports to claim that as NAND flash dies get smaller (as they inevitably will) there is a predictable drop in reliability and an increase in latency to the point of a diminishing return that “makes the future of SSDs couldy.”
According to one source: the researchers chose 45 chips from 6 manufacturers. They did not use specialized NAND flash controllers as are used by SSD vendors such as Intel, OCZ or Fusion-io. Instead their results were baseline and considered “optimistic” because they didn’t include latency added through error correction or garbage collection algorithms.
Really? No controller & no error correction & no garbage collection? That’s like putting a racing car on the track and forgetting the tires — results will be poor. Here is the entire paper:
