RAID 5 allows losing a single drive to be no big deal. Also, when done
right, with the right number of drives and a good RAID card, is has
performance like RAID 0, or even better.
For reading, yes.
But for writing, it will always be slower. An "enterprise" RAID
controller can greatly mitigate the RAID-5 overhead by using a *lot*
of cache, but that same amount of cache applied to striped or
mirrored/striped drives will just make them that much faster...
