@ daedao:
My answer "I would not run the SSDs as RAID0 without having TRIM support" was valid just for me and not for all other SSD RAID0 users.
So there is no difference between Ourasi's and my statement.
Furthermore I want to mention, that the relevance of the TRIM support does not only depend on the usage of the SSDs, but on their intern Controller and Firmware too. Not all SSDs have a very effective Garbage Collection.
