- taspeotis 11y agoMost of that stuff got ironed out ~2011. E.g. SandForce controllers: https://en.wikipedia.org/wiki/SandForce#Issues https://en.wikipedia.org/wiki/SandForce#Issues
- thrownaway2424 11y agoAccording to the paper, these are full-custom drives with custom firmware. These are not commercial SSDs.
- coldtea 11y agoWhere did you get that "full-custom" thing? The FA says they tested: "10 different drive models" of "enterprise and consumer drives".
- tangentspace 11y agoThe original paper states the following: The drives in our study are custom designed high performance solid state drives, which are based on commodity flash chips, but use a custom PCIe interface, firmware and driver.
- thrownaway2424 11y agoThe actual paper doesn't describe the drives as enterprise or consumer. Indeed the word "consumer" appears nowhere in the paper. The charitable interpretation of the FA is that its author was making the simplifying analogy of SLC : enterprise :: MLC : consumer.
- velox_io 11y agoI believe the high firmware failures rates only effected a relatively small number of models. Hopefully firmware will get to a point where if the SSD does fail it will be far more graceful (revert to read-only), rather than the sudden death I've seen first hand.
