I doubt, that you will be able to use different mass storage controller drivers with SATA devices, which are connected to the same sort of SATA Controllers.
If your mainboard doesn't have SATA ports of different vendors (for example Intel and JMicron), you should use the Intel AHCI driver for all your SATA devices inclusive the Intel SSD.
The only disadvantage will be, that you have to run the upcoming SSD Toolbox Optimizer manually from time to time, but this will take just some seconds.
Furthermore you can expect an Intel RST AHCI driver in the near future, which will pass the Trim command.
Thanks Fernando, that's what I suspected.
Guess I'll wait for the toolbox to be released and schedule it to optimize daily. The intel drivers are certainly better quality than the microsoft ones.
Is there any disadvantage of using the optimizer over native trim, except for the fact that native trim is working all the time (i.e. whenever there is write activity on the ssd)? Is the optimizer just as effective at restoring the ssd's performance?
