最近重灌了 El Capitan，在找「三星 850 Pro 是否可以用 trimforce 開啟 Trim 支援」時發現了下面的信息：
- Apple warns users on new Trim support in 10.10.4
- Samsung 850 Pro SSD 256 gb slower after firmware update EXM02B6Q. Original firmware EXM01B6Q worked perfect!
- trim does not work with Samsung 840 EVO after firmware update (EXT0DB6Q)
- Samsung SSD 850Pro firmware update queued TRIM problems
