    Hi,

    It seems Yosemite introduced a quite high SSD slowdown. I have 840 Samsung Pro, read speed is 300MB/s, write is 40MB/S (!). It was just fine in Mavericks... I enabled trim after disabling kext signing, the result is the same with BlackMagic.

    Anybody experienced the same issue?

    Thanks!

    Same here with a Samsung 830 Pro on an 2011 iMac
