I have exactly the same experience with a Intel X-25M 160GB G2, FW: 02HA, Win7 64bit.
After the firmware update and running intel ssd optimizer for the 1rst time I had a score of 423 in AS SSD Benchmark:
Now after 10 days without running intel SSD optimizer I get a score of 335 in AS SSD Benchmark:
After I just run the intel ssd optimizer today, I get a score of 418 :
Same question as oplichta: Does the automatic trim really do its job ?
It looks like we need to run intel ssd optimizer in Win7 ?!

Note: CrystalDiskInfo says TRIM is enable after the firmware update.
I have standard Microsoft Win7 x64 driver V6.1.7600.16385 from 21-06-2006.
BIOS "SATA configuration: ENHACED" and "configured SATA as: AHCI" in ASUS P5B Deluxe Wifi (ICH8R).
Win7 was instaled with AHCI enable in BIOS and intel FW updade was done with AHCI enable after win7 was installed.
I deleted the "dayly_schedule_job" from intel ssd optimizer, but now I think we need to run it once a day as it was set by default after instalation.
What are the choices in your BIOS for SATA ports? Enhanced and what else? Hmm...ICH8R just might be the problem.
You should not have to run the Optimizer with MS AHCI driver and BIOS set to AHCI. I have not seen any deterioration of performance using AS SSD tool to evaluate--and I have not used the optimizer.
I remember reading in intel update text to do the FW update with the BIOS set to AHCI.
"BIOS STORAGE CONFIGURATION
This tool will only function correctly with the BIOS SATA ports
configured to "Legacy" / "Compatibility" mode, or "AHCI" mode.
Some BIOS configurations support SATA port modes such as "IRRT",
"RAID", and "Native + IDE" mode, which are not supported by this
Did you install Win7 after the FW update?
You might have already done this or it is probably set this way but you can always double check to make sure that trim is enabled by going to the command prompt and typing "fsutil behavior set DisableDeleteNotify 0" and rebooting. I assume that Windows 7 already has it enabled but it might not...
I installed Windows 7 x64 on two different SSD's with one being before Firmware update and the other after firmware update. I did update in legacy mode and set BIOS to AHCI before booting back to Windows.
The reason I asked you about your SATA ports and what other choices are there is because your Enhanced may be Native + IDE. I have a different MB and my choice was simple, disabled.
10 GB sounds too little ? Remember that my ssd is "only" 80 GB, so 10 GB is more than 10 percent !!! If automatic trim don't do its job because "only" 10% of the space is free, Intel has to correct that quickly ...
My SATA ports are set to AHCI (my choices are "IDE", "AHCI", "RAID"). I have a gigabyte P35-DS3R with an Intel ICH9R chipset. My firmware was installed on a brand new, right out of the box ssd, Win 7 was installed after... and the driver is the MS AHCI... So according to Intel, I have everything to make automatic trim work ...
