So, I put an SSD in my PS4 and it makes such a difference to D2
I've been wanting to do this after watching this video: https://www.youtube.com/watch?v=Ddkm408hzW4&t=1s
I took the plunge, got myself a 500gb SSD for just shy of £50 which is the same price as a new release, and 1/10th of what the PS5 is expected to cost.
It was quick and easy install on the PS4 slim, all I needed was a small Phillips head.
* slide off a panel on the back, * remove one screw to pull the HDD caddy, * swap the HDD for the SSD (4 more screws), * boot it in safe mode to install the OS off a USB.
Within 30 minutes I had my profile and saves downloaded off PS+ and D2 was underway.
At first I was unimpressed, the console UI is only slightly more responsive. Then I booted D2. Holy hell.
I was in the tower before the HDD would have even reached the character select. I ran some Vanguard strikes and the load times between felt about half what they used to be. I can actually change gear before a firefight without my teammates finishing it before I'm back in the action, and I can check bounty progress before being revived. AND I can even preview shaders when loading into the next mission!
It's obviously not PC speeds but it's a significant improvement. If you're on console, do yourself a favour. I've been in a huge rut this season and barely made it past level 50, but knowing I don't have to spend half my play times now waiting to load in has renewed my motivation.
