Yeah... what are you talking about? Enormous memory consumption = deduplication? Otherwise it doesn't seem enormous too me. Sure ZFS made a lot of departures from the standard toolset with all its own stuff... but that stuff is better once you learn it. I can easily get 600MB+/sec reads and writes on my pools with are pretty commodity stuff. One of my pools is 95% full, which is high, and I just tested it and got over ~100MB/sec write ~150MB read.... good enough for me. (Oh, and I just checked, it was scrubbing) Here are my little ZFS peeves: 1. you can't grow raidZ vdevs. Reduces flexibility. 2. I wish there was a version of scrub that rebalanced data across vdevs. By comparison BTRFS is nice, but nowhere close to ZFS. Last I saw a BTRFS scrub consists of cat'ing every file to null... which doesn't even cover the FS and metadata.
