The disk is a Samsung 850 PRO and Samsung actually provide a native linux CLI tool for management. They do say, though, that (for their tool) trim is only supported for ext4. I understand that other filesystems have native trim support built in, but I'm most comfortable with ext3/ext4 at this point in time anyway (although I do use xfs on at least one data storage partition).
Beware of filesystem's with built in trim. Basically if you pass in an argument at mount time, you are engaging realtime trim. If you have to schedule a nightly (or weekly) trim command, then it is batched trim. == Batched trim is basically safe and a performance benefit for any SSD. Realtime trim is a different matter. For almost all SSDs sold (or designed) in 2013 or before, it is a performance hit. Newer SSDs support asynchronous trim. That is the feature need to have before realtime trim is a net benefit. For me, I still stick to batched mode exclusively. FYI: Windows runs batched mode only as far as I know, so realtime trim has not been an important feature for SSD manufacturers.
