Alienware r13 Hard drive issues

Recently I began getting a message that my hard drive was failing. Everything seemed to work fine but it did start to slow performance wise. Occasionally on boot up a “No hard drive detected” message would appear. Restart and it would boot normally. I went ahead and replaced old ssd with a new one however I’m still having the same issues with messages and performance. When I run the hardware test it’s hit and miss if the hard drive shows healthy. I replaced original ssd with a Samsung 990 Pro.
