Pretty sure it’s the Phison E18 controller that is delivering.
MyDigitalSSD didn’t bench very well but it’s transaction time accessing RAM buffers beat my Samsung’s out of the hole.
Application dependent obviously, but years later both work well and one costs twice as much as the famed Samsung.
Looks like Phison improved with each new controller.
My Sabrent external SSD Caddy cost 20 bucks and still 7 years later clones with Acronis first time, every time. I like Sabrent.
