How to read my HDTune graph results?

Alright, so I downloaded, installed and ran the HDTune benchmark for my laptop's harddrive (specs in sig) a few weeks ago and I noticed that the graph lines seemed a bit more jalopy than everyone elses results. I decided to run it again today and I'm posting my results so maybe you guys can tell me whether or not the results are normal (like the Transfer Rates and Access Time) and ways of improving results if needed.



Not sure if this is important, but my HDD's 93% full right now.

 

No I do not think those are good results. The jalopy you speak of is other apps going for things. Even with that your results suck as my 160GB @5400 Hitachi is 40MB/s. Something is wrong, even your seek time does not impress me. Being almost full should not effect the HDD so much.

 

Shut down all the extra toys on your system. Go as far as changing you graphics to basic mode to make sure everything is stable and you can get a pure reading of your HD.

Does your system run in ATA or AHCI mode?

 

That's pretty average results, i think, for a 80GB 7200 drive. I get about the same with my 120GB 5400 drive, but that's a fast 120GB 5400 drive.

 

I'm sure that those drops in transfer rate are caused by other applications accessing the HDD during the HDTune test. In other respects the results look reasonable.

thanks for the advice. i'll make some changes and run the benchmark again soon and post up the results.

as for AHCI or ATA, i believe I have AHCI enabled in the BIOS.

just in case, heres a ss of my HDD info:

 

If the HD Tune info is correct, your drive is running in legacy mode instead of SATA150 (and you have a SATA drive). Can someone report their SATA result from HD Tune to see if it is just incorrectly reading the interface? I can't do it with mine, as the latest HD Tune does not recognize my Seagate 7200.2...........

 

OK, so i ran HDTune again, this time with just about all nonessential processes off, disconnected from internet and unplugged all USB devices. I couldn't find the "basic mode" from the nvidia control panel so I just switched the power settings to "Power saver". Ran the benchmark and got crappier results so I did another fresh reboot, left the processes alone (aside from turning off antivirus and other programs running in the tray), turned power settings back to normal "high performance" and ran benchmark again, and the results were about the same as the first benchmark I ran above, aside from slightly lower CPU usage, .2 lower access time, and the transfer rates were almost the same more or less.

also, the graph remained almost the same as well, with still the jalopy lines. are my test conditions still not right?

also, am I not seeing the benefits of a 80GB 7200RPM SATA harddrive because, as R4000 suggested, I am running in legacy mode instead of full SATA capabilites? if so, how could i correct this?

Thanks for the help so far

 

The minimum, maximum and avarage speeds are in line with the performance of a 80GB 7200 drive. The odd thing is the curve.

That is sata mode.

 

But it is the "UDMA Mode 5" thing that threw me off, as that is the spec for an ATA-6 (IDE) drive........
