I doubt it, unless your MB HW/driver is broken, as usual max transfer rate of 7200 HDD is around 150MB and SATA 2.0 ( 3 Gbit/s ) limit is 300MB Check current HW performance by sth like: iostat -x 3 -m and verify if you are close to expected HDD values under real load/test stress. > I'm also curious if the SATA cables have improved over time, or are > the same cables I purchased five years ago just as good today? If controller works in SATA-300 mode on all ports already, you will not get any benefit from newer (SATA-600) cables neither.
