I have a Caviar 2.5 and these older Caviar's only supports PCI Mode 4, which is 16MB/s. I didn't get the high transfer rates until I went to a UDMA 33 HD. Then, the WD HD's were fast. I have an ASUS P2B-B and get a real mix on transfer rates between the old non_UDMA drives and the new ones. FreeBSD is installed on a 13.1 GB WD drive and it writes at 12+MB/s and reads at 14+MB/s. I figured that if the slow Quantum gave a high rate, then he has a modern mb and it should support UDMA on both channels. The WD wouldn't understand UDMA but should benchmark on the order of 7-8MB/s.
