Trim Enabler cannot support miniPCI-e SSD with SATA2 adapter ?

KingSpec KSM-SMP.5-064MJ is a mini PCI-express type SSD (not mSATA) for some EeePC models.

Trim is also supported.

I tried to install KSM-SMP.5-064MJ into my imac with SATA2 adapter.  

I bought it via Amazon which brand or model number was unknown.

mSATA to SATA adaper (right)

Trim Enabler said "The patch is active but Trim is not working...." even if several rebootings were done.

On windows machine, Trim is supported through miniPCIe-SATA adapter.

And its speed was presented.
