Just purchased a Sonnet Tempo SATA card, here are the xBench results of the SATA card vs the existing IDE to SATA converter I was running, same SSD in each case.
First is my original IDE/SATA bridge card, and second is the Tempo SATA card.
As you can see the results at least with an SSD do not justify the difference in cost, $3.95 for the bridge card and $80 for the Sonnet card.
I would expect better results from a conventional HDD.
I have to admit though, the SATA card allows for a much easier and cleaner installation and very likely better cooling airflow.
