Alot of people are probably wondering which is faster and worth there money at this time. Well with the recent boom and price drops of SATA - more people are thinking about it. You should know the stats of them, to see if its actually worth it. I stumbled across this page, which gives a good comparison of the both. http://www.directron.com/patasata.html They state that Parallel is running at 133mb/s now. and SATA is running at 150mb/s now, and 300mb/s later in a few years. Taking a look at newegg.com, i can get a Maxtor SATA 120 GB 7200 RPM 8mb Cache drive for little over 100 dollars. Worth it? almost seems it to me. Just thought id share that with you...as i was thinking about it myself.
