I see.

Well, I still have an HDD. I plan on getting an SSD in the future, but so far, I'm not "suffering" because of it. Even games like Ratchet & Clank: Rift Apart and Senua's Saga: Hellblade II worked without many problems on my PC.

I have never noticed anything in my life, and I dont plan to start today. 

It's just a few AAA games that take full advantage of the SSD. Yes it's very nice tracks load in a few seconds instead of half a minute in GT7, yet for example NMS still takes forever to load.

Smaller games / indies don't seem to load any faster as you still have to wait for all the splash screens :/

However in AAA games I'm now more inclined to use fast travel instead of actual travel. It's nice fast travel is actually fast now, but it also makes me lose interest in the game faster, steering games more to checking off to do lists rather than experiencing the world.

Of course I can simply ignore fast travel again like I did in TotK. And I will.

I actively go back to play old games so I'm still in awe how fast the SSD is when I go back to a modern game. I'll never take it for granted lol.
However I'm very tolerant of loading in games. The only time it can get to me is when I go back the 8th gen consoles.

If you miss loading screens, you have issues.

Indeed, there is some absolutely brutal screens on 8th gen. The Witcher 3's loading screen is brutal cause I play on Death March the highest difficulty but fear of the loading screen kept me on my toes while fighting  playing astrobot atm clearing up trophies and when I get a puzzle piece or a bot off the path I just commit suicide cause it's faster than trekking back to the main path, sometimes.

People above are wondering why one would miss loading screens but they had their uses and there is something odd about dying anf instantly reviving that doesn't feel video gamey for some reason. It's fantastic though and I love it, don't get me wrong. 

Sadly the SSD does nothing when it comes to installing/downloading/updating games... Still takes forever and a day.

I actually keep all my games on 16 Terabyte Mechanical Drives and keep everything installed and updated in the background, I have always been a PC gamer, so we always had loading screens as our games tended to be larger and more complex than console variants even back in the Pre-Windows days.
It just doesn't bother me.

My fast travel rule is if it is something repetitive like finishing a quest and needing to return somewhere then I fast travel, otherwise I tend to explore.
