I have 4 SSD's in my system and one of those are a Samsung 860 QVO 1TB. It's only about a year old and when I went to launch one of the games that I have installed it seemed super slow. I checked all of my other drives, swapped the sata cables around and the drive is still performing poorly. I confirmed in the bios that something weird didn't happen where it swapped over to sata2 for some reason which it didn't, confirmed its still running on sata3. I ran crystaldiskmark and it only got about 320MB on the read test. I checked on Samsung's warranty page and I should still be in warranty as the drive is less than a year old, and only has 2500GB of total writes. At this point I'm pretty sure the drive is failing which sucks because its the first bad SSD that I have ever encountered or owned but I'm just curious to see if anyone has any ideas that I maybe didn't try before sending it in. I already grabbed all of the data off of it, and if samsung does send me a new one I'll probably end up just selling it and getting the pro version.
