I don't think anyone is gainsaying the desire to have a massive SSD ( or lots of high-throughput storage in general. ) It's more the money involved in order to achieve it. I don't like the idea of attaching a fiscal amount to a hobby or experience tag. A tech or computer enthusiast to me is more about their knowledge, experience, and passion, not their disposable income. To say that someone can't be an enthusiast because of their hardware is the same as saying someone can't be a gearhead without owning a GT-R or better. Now most people passionate about computers will probably have it a high enough priority that they'll budget enough to have a nice machine, but not all can do it. In fact, those people might be considered more "enthusiast" than others because due to fiscal limitations they often tweak every last ounce of performance from their hardware.
I know RAID 0 has become much simpler to implement than it used to, but I still don't like it. It introduces extra single points of failure that I just don't want to risk ( I'm sure we all have anecdotal evidence to contradict each other. ) I don't think SSD reliability is a big concern anymore. I don't think anyone wants to say they're just as reliable as a spindle drive yet, but they're not the anxiety time bomb they used to be either. Again, I'm sure we all have anecdotal evidence to contradict each other on this one too.
I suppose I see disk space allocation one of the costs of ownership of having an SSD, just like premium gas in a high-performance car. My 128GB M4 has enough room for Office, Adobe CS4, my Canon photography apps, GW2, and a dozen other smaller games and programs. The rest go on my WD Black. Now I was able to score a great deal on an M550 today so I'll be upgrading it to 256GB next week. I might transfer a few games over, but I don't have many other programs that would notably benefit from the SSD that aren't already on there. I understand others may have more applications than myself, but you also have to admit the vast majority of people don't have 350GB+ of active games either. I'd have to say 128GB is enough for most people, and 256GB should be enough for most performance sensitive apps tech savvy users want. Of course there will be a few outliers, but we shouldn't redefine our criteria for 2% of the users out there.
If a user truly does have a massive library of applications that all should be on the SSD, I'd have to ask how often each of those are used. The time savings in a SSD are compounded each time the app is run. If you only launch it once a month or less, does it deserve to be on the SSD? In your case, out of the 361GB of games, how often do you even play each of them? Of the 195, do you even play through 30 a month? 20? 10? I'm not trying to pick a fight, say you're wrong, tell you to change your habits, or anything like that.
If it was me, I'd take the 25% I play most, plus another 25% that I might have the whim to play in the next month or two, and load those on the SSD. The rest would either be put on the spindle or just deleted ( with install files archived somewhere. ) For the small chance you want awesome speed for something that isn't currently on the SSD, transferring the game folder from the spindle to the SSD only takes a minute and Steam can rescan the install folder to update where to launch the game.
And sorry about my slightly aggressive response earlier. I've been having a crappy day.
