Determing HD speeds, modes?

[Synaptic71]

I recently discovered that my Barracuda HD was operating in SATA I 1.5GB mode, as I read an article that suggested that I needed to remove a jumper to enable the 3.0GB SATA II mode. After a year, and not realizing, I finally removed the jumper.

I than ran an HD Tune test, and got similar numbers from before I removed the jumper, specifically on my read speeds. I needed to get rid of the 4 year old 18" SATA cables that were in my system, so I replaced them with SATA II compliant 10" cables instead. Still, the same numbers in HD Tune. Now, these numbers may be accurate for my HDD. I can build a PC, etc, but am still a rookie when it comes to crunching numbers, etc. Hence, my posts here on AT for help and understanding. Below is a screenshot of my HD Tune numbers. Perhaps someone here would be so kind as to analyze it, and tell me if those numbers are on target for a Seagate Barracuda 500GB 7200 RPM, 32 MB cache hard drive. I notice that it is running in UDMA mode 6, and was also wondering if that also is the mode that this drive should be running at, for optimized speeds.

Thank you in advance..

Ack, anyone?

Determing HD speeds, efficiency, modes?

How do you determine a HD's "efficiency"?

Edited for accuracy, good Lord.

Now, anyone with any helpful information?

Your hard drive could never transfer data fast enough to exceed SATA I speeds. So it makes no difference if it is in SATA I or SATA II mode.

There's nothing wrong with your old 18" SATA cables either.

Aye, they worked, but I wanted to clear up some space in the tower.

HD Tune showing "-1.0%" CPU Usage. Shows the same for me in my Win7 64 bit system; it usually crashes. Might want to try another program to benchmark your drives and see if the data is the same.

Willdo, thanks Ron.
