Ok i made error scans on both HDs, they both had no errors and these are their speed maps: 1TB HD (the borrowed one) 2TB HD (faulty one)

So i borrowed another HDD for testing, the model is ST1000DM003, installed windows and everything for running it normally, my first test was downloading from steam and guess what: no drop problems on download so i ran the HD tune on both HDs both using their respective windows installation and these are the results: https://imgur.com/a/dECdDQE So basically, using windows on the HDD being benchmarked causes a bunch of drops which everyone knows it, but the problem on the ST2000DM008 persists even when windows is on another HDD, the speed keeps going up and down for almost the WHOLE test, with a HUGE spike to the top in the middle and for no reason at the end it just goes up and "estabilizes", is this enough to open RMA again or should i just give up because this model is just bad?

This is the test using a new cable and another SATA port and still the same results, I will try next to change the sata power cable but i don't think the results will change. Also I like to remember that the steam problem is just one of the problems i'm having, I also get a LOT of stuttering/freezing when the HDD is doing some installations or transfering and also when gaming. Also it's pretty weird that by the end of the test the speed just goes UP and try to estabilize even with the sudden drops https://imgur.com/a/LPFzG3D

Recently i had problems with one of my HDD being extremely slow and yellow warning on Crystal Disk, after that I switched my windows and boot drive to another HDD (ST2000DM008) which I only used for games and steam, but when i started using it for Windows i noticed A LOT of stuttering doing the almost everything, especially when installing something or sending files to it. I ran some tests on HD tune and got these results https://imgur.com/a/92aDsbY which I interpreted as a bad HDD and sent it to RMA. After almost a month, I got a new HDD from RMA and been using for the last 2 weeks, but since it arrived i've been feeling the HDD has the same problems from the old one (even thought they sent the same HDD but the serial number is different) and a lot of stuttering/freezing programs happening, especially when installing a game or transfering files, also when i try to install ANY game from steam it keeps going to 0 mb/s and disk usage drops like hell (this never happened until this new HDD So i got to test this new HDD and for my suprise the results seem pretty similar to the old HDD I sent to RMA and even some speeds look WORST than the old one, so can anyone actually help me looking at these results and actually telling me if the HDD has a problem or not before I open RMA again? Because if I need to use warranty again for something they already sent me I need to be absolute sure to fight for a decent HDD to be sent to me this time.
