I have a 4TB HDD that I use to store music, films, images, and text files. I have a 250GB SDD that I use to install my OS and video games. So far I didn't have any problem with this setup, obviously it's a bit slower when it reads the HDD but nothing too serious, but lately it's gotten way worse, where it just lags too much when I try to access files on that disk, and specially when it comes to listening to music, it's super annoying. I'm using Elisa music player and it just takes ages to load the albums.
Below is my system and HDD information. I think I'm supposed to use hardlinks or something to access those files, could that be a reason? I've never even fully filled my HDD and it's only 3 years old.

Huh weird I do have experience of this happening especially on used drives that are technically beyond their lives, +7 years etc, guess it depends on manufacturer and classification since you haven't personally experienced it. When I say slow down I'm referring to the read and write speed not the platter rpm even though that could happen such as with motor bearing wear. There's really multiple potential hard wear issue that could cause read and write speeds to slow down: head wear, platter degradation, etc. Although i do want to clarify that I'm not necessarily saying its dying or even if its 100% a hardware issue since fragmentation could be the cause. Not even sure if it'll be throwing out errors yet so I can't wait to see what OP updates us with.
Those are signs that the drive is failing - not a "normal wear and tear".
The spindle must spin at a constant angular velocity for the drive to operate. It can't slow down and work since the heads expect the bits to be on the platters in certain locations and to come at a fixed rate. It doesn't slow down over time. HDD motors are extremely precise with feedback to ensure the rate is correct. It's not a simple DC motor.
Same with the heads - they don't touch the platters so I'm not sure why they would be "wearing down." But if they are that's a sign of failing not just "normal wear and tear". In fact if it does touch a platter that's catastrophic...
HDDs are made with excellent precision. I have a drive with a powered-on time of over 8 years and it performs as it did when I bought it. Just because there are moving parts doesn't mean they're bad. We've been making them for many years and have gotten very good at it.
And fragmentation is almost certainly not an issue with ext4.
This can't be overstated enough. Modern mechanical hard drives are a hundred times more impressive than Swiss watches.
