You don't have to use RAID-0 for speed and space with the somewhat greater failure risk.
You can also concatenate them (using the Apple RAID setup screen in Disk Utility) which will simply make them appear as one larger contiguous disk drive. There is no speed enhancement, simply a larger pool of disk space, and there is no increase in risk over a single drive.

This is a rare comment around here but...I don't know
I do know I tried it by mistake, nothing but issues with concatinated. I even tried the terminal commands, no go

Hmm ... that is really strange, hopefully someone can explain this for us.
I have concatenated hard disks many times, but haven't had a need for concatenated SSDs thus far.

My intention was to stripe the 2 SSD's I have into RAID0 for performance purposes. I accidentally hit concatenated, let it be that way for a few weeks, it did not work out. I use rotational drives for data storage. I'm getting about 450MBps peak read/write with this arrangement. (2 M4 Crucials 128GB)
If that is based on the fact that previous Intel drivers meant you couldn't then this is no longer the case.
TRIM DOES work using the new Intel Software.
On OS X, who knows?

LOL
Yup, even when they don't know they still claim they do.
Thanks! I'll keep they in mind. I was thinking that concatenation might actually/finally be useful with SSDs too. :-/ I've concatenated HDDs just for testing & experimenting but since it's not very useful compared to RAID0 never for very long.

You caught that spelling issue eh? I fixed it the second time around hehe
