>How do i build ratio on private trackers in a good way?
All I can tell you IME is sit and wait, wait, and wait some more. And hope nobody bitches at you for not waiting long enough.
>I want to get more storage. Im pretty computer illiterate
Then you really don't need to worry about it all that much, doing shit like RAID arrays and NVM is if you really wanna geek out and min-max to the fullest and don't mind paying 5x the price for 2x the performance. So you really don't need anything more than a few SSD external drives or even really cheap plain ol' Seagates if you don't mind if it's relatively slow but cheap as hell. Especially if you don't mind how slow USB is, hours to copy terabytes across tens to hundreds of thousands of files from your PC. And then copy everything to both drives separately, one after another, so in case one fails you have redundancy to save your ass without having to fuck around with data recovery which can be expensive or a pain in the ass to do on your own. With cheap drives it's not worth the cost in time and money to do data recovery.
