It's ALWAYS better to have FSX on a different disk than the operating system, may them be SSD disks or normal harddrives.

No you will not see any improvement at all in the load times, or very few.
The purpose of moving FSX to a dedicated drive is to improve the read access speed, which limits the micro-stutters. But again, with SSD disks, the differences will be quite minor compared to regular harddrives.

I  installed my second 120 GB SSD I received for Christmas. I  then moved FSX from the SSD it shared with windows to this new SSD.  My FSX configuration now has Windows on its own SSD and FSX on its own SSD. This  resulted in  much faster load times for FSX.

There are two reasons for this. The first is that SSDs have fast read access compared to normal drives. The second is that even though I had both FSX and Windows on the same SSD, my Mega Scenery Earth SW was maintained on a conventional drive and when a flight that included Mega Scenery Earth scenery was loaded, it accessed that data at the access speed of the conventional drive.

Now FSX and all related SW is on the second dedicated SSD.

I have had both Windows and FSX on the same drive and on separate drives.

With the drives being the same kind either SSD or Standard I have seen little difference in performance. You may see some improvement in overall smoothness in your flight (less or no stutters, etc.) with FSX on its own drive. In your case, this would assume that your older drive tech parameters are equal or better than your 1 TB drive.
