I think it's not the case that a database needs to skip all over the disk. For a start you can write to a log at the DB level, but even if you don't at least some modern filesystems are copy-on-write, so they never actually rewrite blocks (well, they do, but not in the read- modify-write sense). ZFS is one such filesystem. _______________________________________________ sqlite-users mailing list sqlite-users@sqlite.org http://sqlite.org:8080/cgi-bin/mailman/listinfo/sqlite-users
