I believe all major OSes support trim in a reasonable way now. afaik it needs hardware support though, so idk how it would work for an SD card.

  Unless you have a RAID card in the middle.

    I don't mean to say it wouldn't work, just that I don't know enough about sd cards to say whether it would/should.

      Sorry, I meant for TRIM being passed down to an SSD.

        oh gotcha. not sure why I thought it was reasonable to think you were talking about a bunch of SD cards in a raid array...

  MMC defines trim as an optional command. But maybe to your point I've generally only seen it implemented on eMMC chips, not SD cards.
