No idea what tool can show ssd and sata3.. and don't know if there is a software that can specifically tell if trim is enabled
There is an approach to check if trim is working.. can make use of disk defragmenter ->configure schedule->select disk
check if the ssd is detected in the list, if it is not found in the list then it means it will not be defragmented, which means it is detected as SSD
and implicitly means that trim is enabled.
Another way is through the help of ssdtoolbox, it has an optimization option which is to enable trim.
maybe others got better input to share
