How can I determine the connection speed for an esata hard drive under Vista 64?

I recently bought a 1.5TB FreeAgent XTreme external drive to store backups. I bought both a .5M (almost too short) and 1.5 cable (really too long). I want to see if I am getting the full 3.0G/sec transfer with either cable. My Norton 360 backup report was of no help because it didn't give me the total backup time so I could do the computation.

"I want to see if I am getting the full
3.0G/sec transfer with either cable.

very easy, 3.0G/sec translates to 393.216 kilobytes or 384 megabytes per second. now copy a file to the eSata drive (e.g. using FastCopy) and you'll know exactly how far away from the theoretical maximum transfer rate you really are.

3.0 gigabit/sec is the maximum speed the interface can provide for, the disk data transfer rate isn't anywhere near that. as a comparison: i'm transferring data between 2 internal SATA drives at a rate of 65 megabytes per seconds.

however, FastCopy will help you to estimate the difference in speed between the 2 cables"
