I am looking at getting 2- 1Tb hard drives for my 2008 MacPro. I always liked WD harddrives. I was thinking og getting the Western Digital Caviar Green WD10EADS 1TB 32MB Cache SATA 3.0Gb/s 3.5" Internal Hard Drive. I not sure of the new IntelliPower because the drive spins between 5400k and 7200. Anyone have any input on these drives?
