"Linux Magazine" article on SSD file systems

"Linux Magazine" recently did an article (referenced but not included in link) on choosing a file system for your SSD. I am now running Fedora 13 on an Intel X25-M as mentioned earlier in SSD experiment. I'm using ext4 and mounting with the noatime,nodiratime options. Performance is snappy. The article had the following benchmark.
                                   MBps
test                     ext2  ext4  ext4 no jrnl   btrfs   btrfs(ssd_spread)
-----------------------------------------------------------------------------
dbench -D /test 10       520   407   428            347     347
bonnie++ /test -s 2048   38    58    72             64      67
The article also had some useful links.
