Keep in mind, the HDD was using ext2 and the SSD was using reiserfs. Synchronous writes on ext2 are faster than all journaling filesystems.
Not three orders of magnitude faster, which is the difference between hdd and ssd random writes.

Three orders of magnitude faster would mean 1000x faster. You probably meant 3 times faster.
SSDs really are 1000x faster at random writes (~200,000 iops vs ~200 iops)
