Completely agree. I would also be surprised if this weren't done at the block level, as ZFS does SSD acceleration, rather than at the file level as the article claims. It's just so much more efficient than caching at the file layer, for not that much more RAM cost (for indexing).
- thereallurch 14y agoApple apparently abandoned ZFS to adopt specific subsets of the technology. Someone else mentioned 4 GB of the SSD is for write cache (log device). Guessing the other XGB is the traditional cache device. Should really improve daily usage performance. Makes sense their benchmarks only go to 4GB.
