I'm looking to see if anybody has any suggestions for the problem that I am seeing. I just built up a new box with a Gigabyte GA-EP45-UD3R rev 1.1 motherboard. Right from the factory, it was running the F9 BIOS which is the latest version available. In this computer, I'm running a brand new Seagate 7200.12 1TB hard drive.
Regardless of how I configure or run this computer (Windows 7 or Vista..both 64-bit), using the Intel ICH10R or the Jmicron (gigabyte purple) SATA ports, with or without the motherboard chipset drivers and SATA drivers, in IDE mode or AHCI mode, I get great throughput results (90-100MB/s), but terrible access times.
The PROBLEM is that the hard drive access time is always been 25-35ms....rather than the 15ms times where it should be.
I've moved this hard drive over to another computer and have tested with HDTune there as well and it was 98.5MB/s with an access time of 15.1ms....which is exactly what I would expect. So, I think that clearly the problem is NOT with the hard drive, but rather the GA-EP45-UD3R motherboard. I even switched out the SATA cables that I was using on the new computer...and re-used the cable that I tested with on the other computer and the same problem persisted.
I should mention that aside from seeing this number in benchmarks, the performance of the machine seems just fine...
Anybody seen this, got any BIOS setting suggestions or do I just have a bum mobo here? I have started up an email ticket with Gigabyte to see if they have any ideas.
