Benchmark read graphs do not show flat line

Benching with HDTach/HDTune, I'm not getting the flat relatively smooth lines on my read graphs that I was expecting and have seen in reviews of this SSD and others.

Do I have a bum drive? I have a few large dips in performance, one right near the beginning of the drive.

It is a Win 7 OS drive, however, the testing is done when the drive is not the current running OS, I use a Raptor with Win XP to bench the Intel 160 G2.

SSD was made in March of this year. No RAID. AHCI enabled (ICH10R). Intel Toolbox ran.

I have the same issue on my x25-m 80gig ssd drive. While everyone elses test the line is almost perfectly flat. Mine goes up and down like a heart beat monitor.

All the other test seem fine and everything checks out on intel's toolbox. Mine is the main os boot drive. So perhaps someone has some answers to this isse or even why it is happening.

Can you capture a screen shot of the results and post?

Thanks.

deusfaux,

JamesWalker had an interesting point. Were you able to try testing based on his recommendations? And if so, what were the results?

Regards,

I originally ignored it because I already stated in my OP that I wasn't benching FROM the same drive that's being tested.

So unless you're saying that running programs on a completely different disk or being connected to the internet affects a secondary disk acting as a data drive... I'm not sure there's anything to investigate there.

The results are consistent across at least those 2 programs, AND when I actually DO run the benchmarks FROM the Intel G2 drive (in Windows 7)

I'm not sure that is it though. As i seen numerous test with the ssd as a active os drive on the internet testing showing flat lines.

deusfaux,

Have you been able to change systems settings and see if that affects results or been able to try the drive on another system? This is unusual behavior and seems like there is some system interaction with the SSD causing the drops.

Regards,

Brady

I do not have access to another system on which to test the drive. That's investigating some kind of hardware issue with my motherboard and build?

What system settings would you have me change? I'm already trying 2 different operating systems.

You might try a different benchmark program , I've found ATTO to be the most reliable ???

But James is right you have to stop all programs from running in background , like norton or anyother security program and you have to be off line .

Correct Voltage is something else to look at a PSU that fluctuates can cause the same thing.

It's a shame you don't have another system to quickly throw it in and compare. (Ideally with ICH9 or 10 chipset).

I suspect you will do a lot tinkering just to find out it is hardware system related issue and it would be really quick to find that out by running it on another system.

What else are you running when you do the benchmark?

To get consistient results, stop all applications and disconnect from the Internet (just unplug modem if you have cable).

I have a couple of ideas, but first please post your drive configuration. In my BIOS it is found under DRIVE CONFIGURATION / ADVANCED. Include all SATA devices shown in priority order. Do NOT move any SATA cables, just post the information.
