You should consider putting redo logs and rollback segments on a small
solid-state disk drive. Most SSD's have micro-second access times for
both reads or writes, whether random or sequential access. There are
studies that show that 50% of all I/O typically go to 1-3% of your
total data. These are the candidate files for SSD and may increase
overall system performance by 200-1000%.
