I want to change my external drives for my Mac Pro (late 2013, UASP supported) over to SSD's. I don't understand much about TRIM, but the drives I would be getting are Samsung 840 Pro 1TB's, and from what I've read, TRIM is important. However, everywhere I've looked online says USB3.0 UASP does not support TRIM. Well, the question then is, does Thunderbolt? What Thunderbolt enclosure will support TRIM?
