40-60MB/s random is a pipedream, and not happening anytime soon. Sequentials should be somewhere between 50 and 120 MB/s on any modern drive though, so there's definitely something wrong with that trace. Access time should be between 7 and 18 ms as well. Check to make sure that there isn't any background activity that is accessing the drive, like a virus scan or a backup.
I must admit, after reviewing them, the "average data transfer rates" of 40 to 60 MB/s on eSATA do NOT specify random access. But they do show a good range of performance at that time, and the superior speed of eSATA over USB2. Note that Firewire 400 is almost as fast, and Firewire 800 is the fastest if you can get it. Or at least, that's how it was 2 years ago.
I believe the hard drives were being sync'd via some RAID software when I ran the first test. I reran the tests and the new results are below. From what everyone says, these readings are normally what to expect.
Yes, it still looks like something is accessing the hard drives when you're running the test. If you go into the vista "Resource Monitor", is the disk graph showing any major activity before you run the test?
I disabled startup services and got a worse result. So I again disabled all non-core services, and restarted in Safe Mode. This is probably the best I can get. How come the results tend to decline towards the end?
The decline is to be expected, although yet again, that isn't as fast as it really should be. The one I posted is what an ideal trace should look like, with the continual decline being a result of the progression from the outer diameter to the inner diameter of the disk.
