What ssd for external storage without trim

I would like to know what ssd would be most suitable to external usb3.0 case. One thing to consider is that there is not trim support via usb port. So either the ssd should be good without trim or it should have other way of making the drive usable instead of trim...
Any good advises on this case?
 
Of-course the speed of ssd is quite high compared to usb, but my miniswap u3 can handle speed of 443MB/s Read 433MB/s Write with Samsung pro 840, so it is fast enough for most usage. The problem in the long run is garbage collection because there is not trim available, so what fast ssd would be best without trim, or is there any that can handle garbage collection without trim?
