One of the Samsung SSD 850 PRO disk achieved a figure of 9.1 Petabyte of data

The cheaper Samsung product – Samsung SSD 750 Evo was able to write 1.2
Petabyte of data, which equals in theory to more than 80 years of constant
disk writing. However, the pro models showed why their price is higher: None
of them wrote less than 2.2 Petabyte of data.
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:

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.
This could be a reason to distrust Samsung based on competency or poor
hardware characteristics.
However, I feel that with their push for microphone-equipped audience
monitoring TVs, there is reason to distrust their products based on
their motives and lack of respect for people's privacy.
