I am getting sequential writes in the 30MB/s and reads in the 40MB/s range using AS SSD benchmark.
Firmware is 2CV102HD.
Could the drive encryption be the reason for this (PGP full encryption)?
Thanks a lot!

Yes, encryption would likely be the reason. There is an issue with SSD Toolbox and encryption, just as with RAID. I assume you are not using the msahci driver for AHCI and need to run Optimizer for TRIM. The following is from SSD Toolbox Read Me:

The Intelâ SSD Toolbox cannot detect the difference between a drive in a RAID configuration and a drive that is using encryption.
· When the Intel Optimizer function is set to run on a drive that has been encrypted, the SSD Toolbox software cannot determine if the drive is in RAID mode or if the drive is using encryption technology

I can't find it now, but I would expect same issue with encryption using msahci driver is possible.

Are you using Windows 7?
I found some more information about the Optimizer that conflicts somewhat with the other information I posted above. This is from the SSD Toolbox Optimizer White Paper:
Q2 Will the Intel® SSD Optimizer work with my drive encryption software?
A2 Yes, the Intel® SSD Toolbox will work with encryption software. On Windows Vista* or Windows 7, a prompt will appear within the Intel® SSD Toolbox allowing the user to force the Intel® SSD Optimizer to execute if the user can verify that their Intel SSD is not part of a RAID array. Clicking "accept" will optimize the drive successfully. On Microsoft Windows* XP, it will work with no additional user input required.http://download.intel.com/support/ssdc/hpssd/sb/intel_ssd_optimizer_white_paper_rev_2.pdf http://download.intel.com/support/ssdc/hpssd/sb/intel_ssd_optimizer_white_paper_rev_2.pdf

Thanks ambizytl!
Yes, I am running Win7 64 bit. I did get the raid / encryption warning when using the optimizer from within the toolbox, clicked ok and it did the optimization fine. It did not improve the performance, though.
In the Windows experience index, I get a score of 5.8. Pretty embarassing.
Just to confirm: my SSDSA2M080G2GN is a Gen 2 drive, correct?
Is there anyting that can be done to improve the performance?
Thanks again, guys!
