I have been using a 1 TB Samsung 850 EVO SSD for almost three years now and it is showing a health status of "Good 93%" in CrystalDiskInfo v8.7.0. This after almost 18,000 hours use and 62 TB of total host writes. This drive is used as an internal boot drive for Windows so has gone through numerous updates and game installs. That sounds good and normal, right? Well, I purchased a 1 TB Samsung 860 QVO SSD on Friday from Amazon along with an external disk caddy to install Steam games. It is plugged into the front USB 3.0 port on my case and only two games are installed on it: Horizon Zero Dawn and F1 2019 (done as a test). Nothing else is installed on this drive as yet. However, CrystalDiskInfo v8.7.0 shows the drive has been used for 40 hours with 482 GB of total host writes but the health status is "Good 99%". Why is this drive showing a 1% life time degradation after just one day? At this rate it'll be at 0% after 100 days!!! It took years before my Samsung 850 EVO boot SSD's health status even dropped from 100% to 99%. Is the Samsung 860 QVO drive defective? I am sure the drive's health status was "Good 100%" when I checked it on Friday after installing Horizon Zero Dawn on it.
