Plenty of decent drives with garbage collection that will stop not having trim being an issue.
More so because the worst case scenario you see in reviews is rarely if every seen in real life anyway. So the few reviews that show terrible performance and slow to recover without trim will both never get that bad and as such won't take as long to recover performance.
Raid doesn't make much difference though, a huge number of game reads are 4kb random reads, look on the SSD shot above, 25-30mb is the best you can expect, and in raid that is the one number that won't go up. highly threaded performance goes up, problem is again games and most single user stuff won't use over 4-5 queue depth and even that is a rarity.
You simply won't hit 32/64 queue depth usage scenarios on home computers and for things like gaming.
However, server based games, lol 99.9999% of everything relevant is loaded and done locally. It's almost entirely worthless with most games having a countdown to game start letting even people with stupidly slow drives get in also. Nice to have faster loading none the less, but raid doesn't make a huge difference over a single drive.
Again top drive 500mb's sequential, top drives in raid call it 900mb's sequential read's. But both have 30mb random 4kb reads, when only 5% of say its a 50 second load, is sequential reads, then that increase to 900mb's reads, really only drops load times by a second or two, if that.
When you're talking about 5-15second loads in most games on an ssd, that ends up being half a second faster, if that.
Deciding between ssd's is a ridiculous thing at the moment, reviews are all different and very few do real world testing (ie, this ssd will load Crysis in x seconds vs y for the next best drive). Also every single ssd out there seems to be best in one particular area but lose in others.
Marvell controllers seem to be the best, Vertex 4, Corsair pro/Samsung, Crucial, probably in that order speed wise. Then you've got Vertex 3's, probably performance wise between the Corsair pro and the Crucial, but maybe less reliable, less good in raid and pretty much being replaced by Vertex 4's now.
I'd personally go 128gb minimum as 64gb drives are almost always significantly slower.
