I'm using various SSDs on a 15-inch mid-2014 MacBook Pro Retina having changed the original SSD for a larger size using an adapter board: all are working fine with TRIM enabled.
I use external SSDs on both USB 3 enclosures and in Thunderbolt 2 enclosures. The Thunderbolt LaCie Rugged and LBD enclosures show that I have enabled TRIM Force and are working but is it possible that TRIM can be enabled on USB in any workaround?
With modern SSDs i.e. Crucial BX MX and NVMe do they have their own built-in garbage collection/TRIM that works in the background?
I'm trying to find an adapter for NVMe (I believe to SATA) so that I can put them in one of the Thunderbolt external enclosures I have. I find the complication of type confusing..
