We come from Earth; we're just more informed. The WD740ADFD's do NOT work on Freebsd 4.x. I'm sure you are talking about the WD740GD. I DID say the NEW ones. They are a lot faster than the GDs. I used them with FreeBSD 4.x with an Areca SATA card and they performed similarly to 15K Fujitsu SCSIs on a heavily loaded squid system. Also when you are using a SATA drive that *works* in 4.x its running in some reduced transfer mode, so you can't expect to get optimal performance or anything close. So "works" is almost a euphemism for "doesn't barf", but they don't really work well no matter how good the drive is. For my needs, its cheaper to go with SCSI than to buy the sata card as there's only about a $250. difference in the SCSI hardware, and I don't use up my slot. Hence, the silliness of operating in the FreeBSD camp. Note that the drives work with 6.x but squid performance doesn't measure up, so again, 4.x with SCSI is the best bang for the buck choice.
