I've been using this old 1.5Tb Seagate Barracuda with 5900rpm for quite some time now, I actually bought it in 2014 from a local store but since at the time I didn't really know much about PC parts I didn't bother checking online, and it turns out the model was manufactured in 2011/2012 and was probably used before I got it.
That being said it worked pretty well for the first 2 years, however recently I noticed the disk usage was going up to 100% very often, especially when there's a windows update, and it takes quite a while to boot as well.
None of this really bothered too much, I have a lot of games and other software installed, so I figured this was probably normal behavior for a HDD with lots of data. But... recently I started getting heavy stutters in games like GTA V and Batman Arkham Knight.
In GTA V it happens after about 10 minutes into the game driving around the city, I get heavy lag spikes and stutters wich also affects the audio, when hitting a car at high speeds sometimes the game freezes for a few seconds, when cops start shooting there's usually lag spikes and the audio cuts out. I noticed whenever I got lag spikes the HDD light would turn on for a few seconds (wich usually indicates the disk is being used a lot), and if I stood still the game was smooth as butter and the light remained off.
In Arkham Knight it's even worse, the lag spikes were pretty much constant when doing any action like entering the batmobile or engaging in fights, the HDD light remains on pretty much all the time in this game (possibly constant 100% disk usage). I do know this game is an unoptimized mess, but trust me a few months ago it was perfectly playable on my system, I even finished the game 100%, it wasn't the smoothest experience but it was definitely playable.
NOTE: There was one rare occurence in GTA V where some buildings started to disappear with LODs everywhere. Only happened once, had to verify the game cache on steam to fix it. I did see some floating cars yesterday though...
I'm about 90% sure this is an issue with my hard drive, but since I rarely ever heard about "hard drive stuttering/lag", I needed to ask does this even exist?
