RAID 0 is not advised on SSDs, because the benefits it provides have little impact on real-world performance. You would have great sequential R/W rates, but that would mean, at best, a few seconds on a DVD-size transfer. On more common situations, like random 4k R/W, the difference would be negligible. In fact, the only real advantage I see is avoiding the trouble of organizing your data across 4 drives.
The kicker is that, for that little advantage, you lose TRIM and data reliability.
It's up to your preference really, does the neatier setup outweight the potential issues you may have? If you are all about performance, RAID 0 SSDs will top benchmarks, but won't be any faster when you actually need it.
You seem to already have the 4 disks, but if you don't, a single fast SSD would be a faster and cleaner solution.
