A small increase in loading times in ESO can be done by doing defrag of ESO game files and sound files, get a defragment software and start defragging them huge files. Huge files mainly fragged by almost everywhere on your HDD so doing defrag putting into one place can help speed up the loading.
OF COURSE
You may ask, who still uses hard disk drives in 2022? Turns out PLENTY. More than you think actually. Despite SSDs are somewhat cheap and easy to get, people still using classic HDDs to get things done, especially for games. SSDs are fast but less durable due to limited writes, you can only write so much onto your beloved $399 samsung SSD and then one day it stops working or SMART system freaks out. Good old HDDs It is slow but handle much more writes than a overpriced SSDs on amazon. Just make sure you don't drop your HDD and you will be fine for almost 5+ years assuming your PC stands in a static place and not shaky.
Think about new consoles, such as xbox and ps5. They all have custom made SSDs on purpose for this. Install / Uninstall games often and your SSD are done for. They did this to sell you more parts and consoles. External SSD helps only so far, Sony does not allow you run games on a external SSD. This is why they have such limited storage. They want your dollars/euros.
