MacBook Pro (mid-2012) SSD Problems

Ok a few months ago I bought a Macbook Pro 2012 and shortly afterwards I installed a Adata 512GB SSD. I cloned my existing Mechanical drive to the new internal SSD and everything went fine for a few months. My Mackbook Pro was booting up in about 11 secs and running like a pro. Well a few weeks ago I started having problems. Here are the following problems:

1. When I close the laptop and put it to sleep it freezes when I wake it up and it becomes unresponsive to the point that I have to completely turn it off.
2. Sometimes when I have to power it on it has trouble finding the internal SSD and after a few minutes I get the blinking folder with the question mark. This tells me it's having problems finding my SSD. Sometimes I have to turn it off and back on a few times or do the clear NVRAM key combination inorder to get it booted up. Once it's booted up it works just perfect. but if I let it go to sleep then its back to problem 1 above.

This has become increasingly frustrating as my Macbook it used for editing pictures from my photography sessions and also editing videos. And I have tried all the different solutions from the internet/google/forums. Well the other night I decided to open it up and install my old mechanical drive back in it. When I turned it on the it found the drive and booted right up. I put it to sleep and it woke back up with no problem and it didn't freeze. I also powered it off and back on a few times and it booted with no problem.

Is it safe to assume that my Adata SSD is dying or could it be something else that's causing this problem? I also did a erase and restore from a time machine backup and had the same results.

I used to work at an Apple certified repair center and would definitely suspect the SSD. Things you could check:

1. Reseat the sata connector on the logic board side
2. Try a different sata cable
3. Try a different ssd
4. Put the ssd in a diffent machine and see what happens

Unfortunately not everyone has multiple ssd, parts and machines to test with. Can you try and claim warranty on the ssd?
