Other Disk Access Protocols
Because RAID is oblivious to the hardware and disk architecture on which it is built, you can use any disk protocol that the Linux kernel supports to build an array. Indeed, if a newer, faster, and more reliable disk protocol (such as Serial ATA) were released this year or the next, it would only increase the usefulness of RAID. Furthermore, if a breakthrough in solid-state media happened in the next few years, these devices could also be grouped into arrays. While disk capacities and throughputs continue to increase, they nonetheless continue to fall behind the curve of increasing user needs.
