RAID 0 is for idiots
I really cannot state it in any lesser terms than I have in the title of this thread.
The risks involved in RAID 0 far outweigh any "gains". With SSDs, because of the lack of TRIM support (and yes I do know that Intel has brought out TRIM support for a very narrow band of Motherboards supporting RAID0 http://www.anandtech.com/show/6161/i...rds-we-test-it) your SSDs rapidly decrease in write performance over a relatively short period of time.
Sequential writes to the RAID0 using SSDs will initially be faster than to single SSDs however random writes to a RAID0 are rubbish from the get go and that is even without figuring in the degradation of performance due to lack of TRIM support I mentioned above.
Yes reads from the RAID0 will be faster but not really by all that much subjectively. And when I say "subjectively" it has been shown repeatedly that for something in computing to be actually realised by the user to be faster, it has to be at least 20% faster.
What exactly is the risk? If one drive in your RAID 0 configuration fails for any reason then you will lose EVERYTHING. Now this is not subjective, it is very objective, completely factual, and very fatal. That is just not worth it and I would really like to hear the arguments of anyone who thinks it is.
Now conceivably two 120GB SSDs in RAID0 could be backed up and restored in a reasonable time, but what about two 4 TB harddrives?
And don't give me this tosh about, "I have been using "xyz" in a RAID0 and have never had any problems". That's like someone saying, "I (or my dad, or grandfather) fought in WWII and didn't get a scratch, so wars are safe and can't hurt you".
I was Senior German Engineer for Enterprise Disaster-Recovery Tech-Support and I am more than well aware of what happens when people approach their systems with more optimism than sense, when things to horribly wrong.
