Get a 12 or 16  or 24 port Areca card and have a few hot spares and  
you will see SATA fly for less money than SCSI with higher storage  
and as high or higher reliability (RAID 6 plus hot spares)...

I used to be SCSI only but these new cards and drives offer a lot  
more for the money and you can make up for reliability by sheer mass  
and raid 6 and hot spares :-)
