Stubborn as I am, I continued researching. Found that SAS Controllers are designed to use UNMAP, TRIM being SATA counterpart. I've found no documentation on how to configure SAS2004 to send UNMAP commands, only glossary documentation that a filter driver needs to be utilized. Likewise, I've never found just what the wdcfg.exe utility is capable of configuring i.e. UNMAP, 512 vs 4096 block config... anything of usefulness.
I found a utility called PerfectStorage 3.0, that scans every block sending UNMAP commands freeing drive space. The utility works wonderful. I'll note it only operates on mounted drives, so if you use Partition Master to resize partitions you'll need to attach SSD to motherboard so TRIM can be utilized during sizing. Samsung Magician Optimizer TRIM's entire drive, including unpartitioned area... it's recommend running periodically especially after major system changes.
TRIM and stability were main reasons I removed 9211-4i from system. I have since precisely manually configured motherboard memory timings, ran MemoryTest86, and slew of other tests, confirming system is utilizing all 4gb of RAM and preforming excellent. Support for A8N-SLI Premium was abandoned years ago, myths that A8N-SLI Premium can't utilize 4gb RAM and or is unstable with Windows 7 x64 is not true.
Only glitch remaining is 9211-4i preventing full power-off at shutdown, thus preventing auto restart as well. I run PerfectStorage daily, and after every major change/deletion of data, configured partitions so 50~% free space and 10+% over-provisioning. Clean as a cat's ass.
