Re: Question about memory (ram)
Ok I'll cover the ram thing first, then I'll get onto the SSD side of things.
Upgrading from 8 GB > 16 GB of ram is really not required unless you're hitting like 90+% memory usage a lot of the time in my opinion. Reason being, any lower and you won't notice any performance drawbacks. But if you're getting up to like 7 or 7.5 GB used, might not be a bad idea to upgrade. As for why gaming computers today have 16 GB of ram, I believe it's because of two reasons. 1. Games are only going to get more and more ram intensive as time goes on because we'll add more and more content to them, allowing for a more rich and diverse gaming experience. 2. It is becoming more and more common to record gameplay and upload it to youtube. For this reason, many prebuilt gaming rigs are starting to come with more ram because programs like Adobe Premiere will absolutely eat as much ram as you can give them when you really start using the advanced functions of them. (Don't even get me started on the CPU usage it uses when rendering).
As for not filling up an SSD to its max, there's a reason for that too. If you fill up any storage medium to its absolute capacity, you mess with the operating system's ability to generate a page file. This page file is used to store things that aren't directly needed by any programs or the OS itself at any given moment, but are still relevant bits of info that might be needed later. A cramped page file = majorly sluggish performance from what I've observed as a technician in the repair workshop.
Yeah, I'm the boss 😂😂 FIGJAM 😂😂
