I'm not trusting Samsung when it comes to SSDs anymore, ever since they botched the firmware for 840 EVO where it periodically(actually at least once per day!) rewrites everything in order to improve read speeds(except when this rewriting takes place and lasts for hours, during which the random read speed for 1 thread 4K is no bigger than 2 megs per sec), no doubt at the cost of disk life and yet without updating the S.M.A.R.T. LBAs written counter: https://www.anandtech.com/show/9196/samsung-releases-second-840-evo-fix There used to be a system-wise OS freeze whenever the SSD just passed another 1TB of bytes written which took like 1-2 minutes, and those are now happening at least once a week. The bad thing is that you can't roll back to any previous firmware version and there's no way to stop this automatic rewriting from happening.
