I have 250gb, but I am a simple man. I uninstall the games I don't play and I dont downloading game more that 50gb because its just stupid.
Pc has 4 TB of SSD Storage, 2 M.2 drives one SSD, then a 2 TB HDD for 6 TB total
With all my games consoles I have 8TB combined. On my desktop I have 16TB.
It might seem like a lot but I manually back up my console games in case the disc gets damaged or the disc drive fails.
Xbox Series S - 500 GB internal, 2 TB HDD for older games .
PC- 128 G boot SSD, 1 TB SSD for games, 4TB HDD for other storage.
I wish I had nvme but my build is a little bit of a dinosaur.
My desktop has roughly 350gb of a terabyte left after only a couple years. Definitely gonna have to delete a bunch of files in order to clear up space. That, and actually complete some of the games I started so I can uninstall them to save space.
Hell, I might even have to uninstall Portal 2 since it's the biggest offender of all the games on my PC, if I recall correctly.
Edit:
Just looked it up and Portal 2 is only taking up 12.94 gb where as Cities: Skylines is taking up 16.87 gb but that's not the end of it. Danganronpa V3: Killing Harmony is taking up a massive 21.77 gb and Steam itself blows all of that out of the water, taking up 71.12 gb on my computer and is the largest program on it as well. Closet other non-game program on my computer takes up 70 gb less at 1.06 gb which is insane to me!
I have 1 TB of nvme storage on my main machine (one ssd). I upgraded a few months ago and I need more storage.
SSD 250go : OS HDD 2To : Storage SSD NVMe 1To : Games (will probably upgrade to 2/3To)
6TB SSD, ~90TB HDD (actually ~120, but the rest is parity).
Photo editing storage gets intense when modern cameras are taking lossless RAW images at 20fps. Video editing storage is honestly just insane to begin with.
Games are a few hundred GB on the SSDs
I haven't run in to any space issues yet since I tend to uninstall games once I'm done playing them. My PC has a 256GB SSD for OS/Win10 and 1TB SSD for Steam. Street Fighter 6 and Bioshock RM are the only Steam games I have installed. I forget how much storage my laptop has, but it has Among Us and Bioshock RM installed. My PS4 has a 540GB SSD and it stores Black Ops 3, Garden Warfare 2, Tetris Effect and a couple other party games.
Switch has 64+256 gb
Pc has 5 tb ssd + 12tb hdd and looking to an eventual NAS down the line
PS4 has 1tb
Current laptop has 256gb ssd + 1tb hdd, thr laptop that will replace it (Framework 16) i have planned for 6 tb ssd
