SATA/300 is 3 Gb/s, not 3 GB/s. There is also a 8/10 encoding to take in
to  

account, which puts the actual maximum transfer speed to 300 MB/s. No  

actual drive can deliver a sustained write speed that high though; a  

really fast drive might approach 100 MB/s. At that speed it would take  

roughly three hours to fill the disk, assuming that the source disks can
  

deliver data at the same speed and the CPU can keep up.
