Hold on there. HP makes SCSI and SATA versions of many of their servers, the model numbers are almost identical between them. I think the only difference in the servers is the SCSI ones have an additional card. Now, before you go any further on Windows drivers you got to understand something. Win XP came out before SATA and Microsquash never put in the primitives to support the higher SATA speeds in XP. So in order to get faster speed you gotta write your Windows driver to look like a SCSI miniport driver. MS also don't certify SATA for WCHL so if you are selling SATA raid chipsets and you want to slap their filthy WCHL certification sticker on your product box, once more you got to write your driver to look like a SCSI driver. You take a very serious risk whenever you compare features of windows drivers and FreeBSD drivers and attempt to draw conclusions on hardware.
