"TRIM Support when hyperduo is enabled"...
I have been vexed by this question after having installed a Marvell Hyperduo PCIe card from SIIG. Samsung magician will no longer detect the SSD nor the Optimize function of Windows. They all see it has one logical drive which makes sense, since Hyperduo created one single disk array of my SSD and a 1 TB HD.
I couldn't find an answer to this question and documentation from Marvell is sparse. I have emailed SIIG asking this very question.
Then I stumbled upon a utility called "TrimCheck" that does a test of the TRIM function.
I ran it and it claims the TRIM function is working after a small test of creating and deleting a file' I believe the Marvell drivers must be doing that in the background.
But you can check it out for yourself by downloading this utility...

Or you can try this tool from Crucial. I haven't tried it yet but I will when I get home.

But other than that.. I am loving the hyperduo. I have a 250 GB Samsung Evo and my PC has become a tablet. Didn't know the HD could be such a bottleneck for my beast of a PC. It's a DELL T5500 with Dual Quad Core Xeon's. Now its really fast!
