For a consumer desktop system, which setup of SSDs would be more reliable over the course of months?

1. A single disk that offers TRIM and/or utilites for maintaining it - e.g. The Intel SSD Toolbox.
2. A RAID of two less reliable disks in a mirror, with the TRIM/Toolbox not being usable through the RAID controller.

A single, reliable disk or a mirror of less reliable disks?

Anecdote: I'm trying to decide between keeping the two OCZ Vertex Plus's that I have in a mirror (They get miserable reviews for reliability) or going for an Intel branded one (Which have good reliability stats).
