Yeah people tend to make that observation every console generation (or when emulators pick up for a given one) and we run the numbers on things. Reasons vary -- some want the ultimate game playing experience, others are for various types of archival (games, Scene and pure being the big three camps), some want to do analysis on the entire software library (I have long maintained I wanted to do something for
https://gbatemp.net/threads/the-various-audio-formats-of-the-ds.305167/ to see how many games do different things for audio but have yet to get around to it). Similarly with the rise of optical media then sizes ballooned (I forget the exact size but every non optical non arcade system up until the GBA is considerably less than 50 gigs, did not check what arcade MAME sets are at right now but not too far off that either, not sure what a complete PS1 set clocks in at but I would not be surprised to see it higher than everything that came before it. Some also come the other way and contemplate compression -- in previous discussions we have done the Wii and then wanted to figure out how to scrub isos such that is suitable (without it every game is essentially a single layer DVD of random data that you can't compress, however we also saw most of the original xbox isos get redumped when the 360 came around and employed better security and the PS1 scene was a time of 4000 competing optical iso formats, several of which were used as "unofficially" they did better against certain types of anti piracy protection so that is always a nightmare as well).
I would also stress the need to consider backup in this. Ideally you would have two or three setups -- RAID is great but fire, theft, lightning, power supply wanting to take a few fools with it on the its way out...
Also while PS3 games are quite large when all is said and done it still has to be looked at relatively and a loss of a single drive up in the many TB is dozens of games. RAID is designed to handle this but... so you have two drives manufactured on the same date/batch, same time powered on, likely similar amounts of data flow, same heat profiles during all this (same case and all that) and one goes pop. What sort of money would you put on its mate holding up too much longer?
Reporter wise then if you report news (
https://gbatemp.net/forums/user-submitted-news.156/ , or indeed see the sorts of things on the portal ), do reviews (
https://gbatemp.net/reviews/ ), make interesting discussions or writeups of things and otherwise contribute you will get noticed. Occasionally we have contests for tutorials/guides and other types of writing -- while they are contests it is not like the site staff don't pay attention. Right now we are seeing the rise of the Switch hacking and while I don't hold out too much hope for it to equal earlier devices (so many of the things that made it work there are no longer in play or have far cheaper, easier and superior alternatives) it will probably still generate a large volume of things to sift through, keeping on top of things there will be the easiest way but if you want to do other things it is far from impossible to get noticed there.
