Question I'm hearing that the new SATA drive can go much faster then SCSI is this true?

Not yet. There are a lot of things that go into the performance of a disk drive, but a few of the most important ones are rotational speed and seek times (how long it takes the heads to move to a new track). Right now top end SCSI drives are still 50% faster in rotational speed (15,000 vs. 10,000 rpm) and have faster seek times (3.5 ms vs. 4.6 ms)
I got these numbers by comparing a Seagate ST3146854LC <http://www.seagate.com/ww/v/index.jsp?vgnextoid=443d99f4fa74c010VgnVCM100000dd04090aRCRD&locale=en-US> which is a 15,000RPM 146GB Ultra320 SCSI drive to a Western Digital WD1500ADFD Raptor <http://www.westerndigital.com/en/products/Products.asp?DriveID=189>, a 10,000RPM 150GB SATA drive. Both of the drives are considered to be the top of the line for their respective class.
