Of course, RAID5 won't be the best in the RAIDs, it's a compromise solution between redundancy and speed. Maximum speed: RAID0 (but no redundancy and increased risk); maximum security: RAID1 (but slower); acceptable redundancy and good speed: RAID5.
And ALL of the above configurations, are BETTER than a single disk configuration, redundancy- and performance-wise. In RAID5 reads are distributed, so in reading you get almost the maximum performance of RAID0. Writing is the pig for RAID5.
