SSD Raid 0??

Ok, so I just got my X25-M and have installed it. Everything is literally instant!
My question is, why why why on earth would anyone raid these? They lose trim, and maybe they get more performance but... can you get faster than instant? Before I've even thought about the fact an app should be loading,.. it's there!
So really... why are people raiding SSDs?
IMO it's expensive, can't have much real world performance boost, and loses the TRIM ability ( On most of them, I do know a few don't ).

What are your thoughts on this?
Would be nice to hear from someone that has Raided them and why.

only a single x25-M user here but imho, whilst everything in windows is pretty instant, games could load quicker for those the install games on their SSDs not that im suggesting the my games arent loading extraordinarily fast now anyway.

You can get higher bandwidth when raiding SSDs.

There's a video floating around where samsung raided together 24 SSDs (each at ~200 MB/s) and got 2000 MB/s overall read/write.
Latency certainly won't be any less though, not that it's something you'd notice.

And that thing about real world performance boost? Yeah, search the vid.

Ps. Applications load instantly even on my old IDE hdd thanks to superfetch either way, so that's not really much of a difference. It's more about copying large files.

who needs trim with ocz raid0 you dont need trim because the new 1.5 firmware does the job

and this is why i use raid0:-

for faster game-map loads/faster boot /faster write

been using these since june 2009

2xagility 30gb ssd raid0 on sb750 southbridge no doubt ich10r would be faster

the writes are over 4 times faster than x25-m and reads are nearly twice as fast

win7 64bit installs in about 5 minutes

Not really read up much on SSD so heres a noob question

what does TRIM actaully do?

I dont know what software you use but obviously nothing demanding.

I've raided about 4 lots of SSD's including two X-25M's and now two Crucial RealSSD's. The thing with SSD's is that they scale very very well with RAID0, unlike HDD's, you pretty much get exactly 2x the speed.

Things that see a speed increase are boot times, game loading, video editing, and start times for my image, web design, and 3D modelling software.

None of the SSD's i've RAIDed have lost more than about 2% performance over time so i'm not bothered by TRIM, and i upgrade SSD's atleast once a year anyway. But if you really want to TRIM the drives you just delete the RAID array and format each drive which will TRIM it, then RAID 'em again.
