The RAID technology may offer two of the three desirable value: (relative) inexpensiveness, speed or reliability (RAID 0 is fast and cheap, but unreliable; RAID 6 is extremely expensive and reliable, with correct performance and so on). A common phrase in data storage is "fast, cheap, good: choose two". The same saying has been pastiched in silent computing as "fast, cheap, quiet: choose two".
