Well, even 14.4 MB/s is on the low side. Try running the optimizer from SSD Toolbox and see what happens. As a point of reference, I am including a test of mine that is also from an 80GB Intel G2 SSD. Do you also have a G2 SSD?

I ran the optimizer and results are still the same. Also it is a gen2 drive

3. Re: Intel X25-M 80gb low 4k read/write speeds
Are you saying there was a time in the beginning when you had results similar to mine above, or were your test results always significantly worse than mine regarding 4K with AS SSD benchmark tool?
Do you have the SSD connected to first SATA port? Do you have any other hard drives that are not SSD connected?

4. Re: Intel X25-M 80gb low 4k read/write speeds
In addition to the above, are there any issues in Device Manager? Are you using the latest firmware update? Can you post a screenshot from AS SSD showing test results?

5. Re: Intel X25-M 80gb low 4k read/write speeds
I'm thinking my G2 is (slightly?) defective. It makes an awful high pitched noise while I run this test. Also my scores are quite a bit lower than yours. Possibly due to the different version of AS SSD Bench... but seems rather doubtful considering the large variance.
any thoughts?

Your partition number (in green) seems odd to me , mines 1024 k, Also have you updated to the latest firmware? as its not shown on the as ssd screen correctly. Also the whining noise seems to be common if you google it you will see what i mean. And try the msahci driver, assuming your using ahci mode in bios.

That partition offset is normal if you've got the Win7 100 MB partition in front of the main partition.

How do you switch to the msahci driver?
As ZXTT95 indicated, yes, I have the 100MB partition Win7 installed.

Ah I see, ok to switch to the msahci driver go to device manager and go to ideata/atapi controllers,then right click the ahci channel and click update drivers,browse computer for drivers,choose driver from list, it should then give you the option of microsfts standard achi driver or the existing driver you have installed.

In your case, you re-install Windows. The SSD controller driver shown in your test results is "iaStor". IaStor is the driver for Intel Matrix Controller or Intel Rapid Storage Technology controller, and has taken over all your disk drives. You can roll this back to the original Windows controller, for which the driver is Intel iaStorV. All of these are Raid controllers.But you cannot change the current setup to non-raid AHCI without starting from scratch, and setting your machine bios option to AHCI. You will find out that you do not currently have an entry in Device Manager for SATA IDE/ATA controllers, and you cannot create such an entry for the SSD, let alone change its driver.
Maybe you need the Raid controller for your system. If so, then all drives use the Raid controller, including singles. It's a bitch. The upside is that the Intel Rapid Storage Technology driver works just fine. The downside is that, currently, your SSD is now behind a Raid controller, and is not accessible by AHCI Trim commands and the like, including the SSD Toolbox. But that might change later.

I was able to switch to the MS driver but my scores didn't change much. 4k read/writes are still real slow. Other concern is the access times, they're about 2x slower than what I've seen around. Ah, well.
-
12. Re: Intel X25-M 80gb low 4k read/write speeds
My scores are about same as yours, I score between 370-380. I know its annoying but I think its something we will have to live with. Allthough my 4k read/writes bother me there 15mb/s and 38mb/s.

14. Re: Intel X25-M 80gb low 4k read/write speeds
I am having the same issue. This is in vista with my having to first edit the registry to reset the controller, then turn on AHCI in bios, then when vista reloads it loaded the driver Standard AHCI 1.0 Serial ATA Controller.
Any advice would be much appreciated. I have run the optimizer, it is one of 3 drives on the sata controller and is just an empty data drive at this point, not running OS or anything on it. My motherboard is a GIGABYTE GA-P35-DS3L P35+ICH9.
