I like this! A few notes: - Some figures/drawings would help a lot, to get article more accessible I imagine just very simple examples, eg: -- how is a very simple file tree is laid out as B-Trees -- which transactions (TIDs) are made some simple sequence of filesystem operations - Some more comparison with oher filesystems, there is a little in the performance section I guess people will ask 'Why another file system?'; you do describe a lot of goals, but don't mention that no existing achieves all goals (or watever reason you see as primary).
The simple things: - Drop 'CD', spell it out; make me think 'Compact Disc'. - there is still a few missing s/then/than/ -thomas
