It might matter for copy speed, but since already SATA II is 3.0 Gbit/s (that's 375 MB/s), I think you'll find the bottle necks elsewhere than in the SATA bus speed alone.
You can stream 1080p/12k off an old IDE hard drive with no problems at all. My RAID5 is SATA II and it'll punch out 4 simultaneous 1080p streams at the same time as it caches a billion parts of an nzb downloading at 14 mega BYTES per second. The bus will not be the bottleneck. Nor will the drives.
I using Windows also, that's apparently not the issue.
