RAID 0 SSDs provided the best bang for the buck in the early days of SSDs.
Most modern top range consumer SSDs now reach speeds (in the 500-600MB/s range) that are about as fast as SATA III (600MB/s), so it's not so interesting anymore, but RAID 0 will be interesting again when SATA's upgraded or replacement technology will appear. It's been over 4 years since SATA III after all, that's like 2 human generations in IT, it's high time for an upgrade or a new technology. PCIe SSDs like OCZ' Z-Drive R5 already reach speeds over 10 times faster than SATA III, so a few of them can (and do) already saturate PCIe 16 GB/s bandwidth.

Still RAID 0 striping provides a more fluid data stream that will always saturate SATA III, which a single SSD or two RAID 1 SSDs can't always provide. The waiting time does not lie with the mechanics of the drive anymore, but there is still some buffering and queuing time, or plain waiting time caused by the difference between the SSD data access speed and SATA's maximum throughput.
